Rock cycle- the interchange in states of rocks from one to another.
Igneous rocks- when molten lava cools and solidifies it forms igneous rocks.
sedimentary rocks- they are broken on wearing of earth's surface.
Metamorphic rocks- they are formed when  igneous rocks and sedimentary rocks undergo immense heat, high pressure and weight of overlaying rocks.

Rock cycle is conversion of three types of rock into one  another,.   namely sedimentary rocks igneous rocks and metamorphic rocks.

   1     The beginning of formation of primary rock that is igneous rock is from Magma under the earth.    When this magma comes on the surface of Earth and cools and solidifies it forms igneous rocks.

2.    The formation of other two secondary rocks namely sedimentary rocks and metamorphic rocks takes place through  the primary rock called igneous rock.

3.   Sedimentary rocks are formed when igneous or metamorphic rocks are broken into small sediments by weathering and erosion.

4.   metamorphic rocks are formed when igneous or sedimentary rock experience intense heat and pressure under the earth.
5.     Igneous rocks can be formed back when Metamorphic and sedimentary rock are melted in mantle and come on the surface through activities like eruption . When this magma cools and solidifies It forms of igneous rocks.
6 Hence we see a  Rock cycle working in the nature where all the three rocks can be converted into one another by three natural processes :
1  weathering and erosion @ sedimentary rock
2 heating and pressure@ metamorphic rock
3 melting and cooling.@ igneous rock.

This is a cycle in which the Rocks undergoes several types of geological transformation due to heat, pressaure, weathering, erosion etc. In this, the rocks change their shape and composition. In other words, we can say, it interchanges from one form to another. This is a never-ending process in which rocks are formed, destroyed and formed again. The different rocks formed are Metamorphic rocks, igneous rocks, sedimentary rocks etc.

# data[].attributes.body
Rock Cycle is a process in which due the rock undergoes various changes to interchange its form. There are three types of rocks that comes under this cycle namely Igneous rock, sedimentary rock and Metamorphic rock.

Metamorphic rock
Magma is produced when rocks are melted. This melting can occur when a lithospheric plate descends into the Earth’s crust at a subduction zone, or when a mid-ocean ridge opens up and produces decompression melting in the athenosphere under the ridge. When the magma solidifies, it becomes an igneous rock.

Sedimentary rock
Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting detrital material deposited in marine or terrestrial basins. If the sediments are buried under further layers of sediment, they can become lithified to produce a sedimentary rock

Metamorphic rock
Conversion to metamorphic rocks requires conditions of increased temperature and/or increased pressure, conversion to sedimentary rocks occurs via the intermediate stage of sediments, and conversion to igneous rocks occurs via the intermediate stage of magma

Rock cycle-
rock cycle is the process in which a rock changes into another type of rock

IGNEOUS ROCKS are formed when a volcano erupts and forms layers of lava on the ground. The lava then cools and solidifies into Igneous rocks.

SEDIMENTARY ROCKS form when particles in Igneous rocks settle out and layer up into sedimentary rocks

METAMORPHIC ROCKS originate when rocks are exposed to heat, pressure and reactive fluids (such as hot mineral-laden water, etc.).

# data[].attributes.body
There are three kinds of rock: igneous, sedimentary, and metamorphic.

Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.

There is kind of interchange in the state of rocks from one type to other.This interchange is called the Rock cycle of the Earth's crust.
On the basis of their mode of formation, geologists have classified rocks into three groups - igneous, sedimentary and metamorphic.
Igneous rocks: Igneous rocks are formed by the cooling and solidification of Magma into Lava. These were the oldest rocks to be formed, so they are also called 'primary rocks' . All other rocks are derived from igneous rocks. Granite and basalt are examples of igneous rock. Igneous rocks may be formed by cooling on or below the Earth's surface. Depending on whether they cooled and solidified on or below the Earth's surface they are called extrusive and intrusive rocks, respectively. Either way, they have a crystalline structure.
Sedimentary rocks: Rocks are broken down by the wearing down of the Earth's surface. We call these processes weathering and erosion. The broken material is dislodged, pickd up, transported and then disappointed by various means - gravity, water and glaciers running downhill, wind and sea waves. The broken rock material called sediment is spread and laid in lowlands, lakes and ocean beds. The sediments get deposited layer by layer over time, get compacted by the weight of overlayin rocks and water into solid rocks. Sandstone, shale clay, limestone, chalk, corals, gypsum, rocksalt and limestone are some examples of sedimentary rocks. Sometimes, remains of animals and plants get trapped in layers of sedimentary rocks. They are called 'fossils'. Coal and petroleum were formed when remains of vegetation and animals were buried within layers of other sediments.
Metamorphic rocks: Igneous as well as sedimentary rocks, when subjected to immense heat, pressure and weight of overlaying rocks, undergo changes in their appearance, chemical properties and character. They are transformed or changed completely. Rocks formed in this manner are called metamorphic rocks. For instance, limestone (sedimentary) would change in marble; granite (igneous) would change into gneiss after metamorphism. It may take millions of years for these changes to occur. In case, the original rock melts in the process, it becomes an igneous type.

First let's talk about igneous rocks - igneous rocks are formed when the hot magma inside the earth cools down then these rocks are formed. Then comes metamorphic rocks - these are formed when the igneous rocks are compressed by the pressure and the heat of tectonic plates of the earth. Then sedimentary rocks - these are formed when the igneous rocks breaks because of the weathering and erosion they become sediments. When the sediments come together and stick close to each other for a long time they become hard and strong rocks which are called sedimentary rocks

ROCK CYCLE= The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another. Plate tectonic activity, along with weathering and erosional processes, are responsible for the continued recycling of rocks.

SEDIMENTARY ROCKS= Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.

METAMORPHIC ROCKS= Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism.

IGNEOUS ROCKS= Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.

TYPES OF ROCKS AND ROCK CYCLE
1. IGNEOUS ROCKS -  The igneous rocks are made by cooling and solidification of magma into lava. These were the oldest rocks to be formed that why they are also called PRIMARY ROCKS. All other rocks are derived from igneous rocks. Examples are Basalt and Granite. Igneous rocks may be formed by cooling on below the earth's surface. Depending on whether they are cooled and solidified on or below the earth's surface, they are called intrusive and extrusive rocks respectively. Either way they have a crystalline structure.

2.SEDIMENTARY ROCKS- Rocks are broken down by wearing the earth's surface. We call these processes erosion and weathering. The broken material is disloged , picked up
Transported and then deposited by various means -
Gravity, water and glaciers running downhills ,wind and sea waves. The broken rock material called sediment is spread and laid in lowlands, lakes and ocean beds. The sediment gets deposited layer by layer over time, get compacted by the weight overlying rocks and water into solid rocks.

3.METAPHORIC ROCKS - Igneous as well as when subjected to immense heat , pressure and weight of overlying rocks, undergo changes in their appearances, chemicals properties and character. They are transformed or changed completely. Ricks formed in this manner are called metaphoric rocks.
For instance,
Limestone
(Sedimentary) would change into marble and granite (igneous) would change into gneiss. It may take millions of years to occur.

ROCK CYCLE
Metaphoric rocks are not only subjected to change under heat an pressure , they may be weathered , ended , deposited and compacted to from sedimentary rocks. There is a kind of interchange in the state of rocks form, one type to the other type of earth's crust. Through thus process old rocks are transformed into now rocks by means of erosion
deposition , pressure , melting and cooling. Its an endless process.
THE PROCESS OF CHANGING ONE TYPE OF ROCK INTO ANOTHER TYPE OF ROCK IS CALLED ROCK CYCLE.

# data[].attributes.body
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rocktypes: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
When rocks are pushed deep under the Earth's surface, they may melt into magma. If the conditions no longer exist for the magma to stay in its liquid state, it cools and solidifies into an igneous rock.
Epigenetic change (secondary processes occurring at low temperatures and low pressures) may be arranged under a number of headings, each of which is typical of a group of rocks or rock-forming minerals, though usually more than one of these alterations is in progress in the same rock.
Rocks exposed to high temperatures and pressures can be changed physically or chemically to form a different rock, called metamorphic.
Rocks exposed to the atmosphere are variably unstable and subject to the processes of weathering and erosion. Weathering and erosion break the original rock down into smaller fragments and carry away dissolved material. This fragmented material accumulates and is buried by additional material. While an individual grain of sand is still a member of the class of rock it was formed from, a rock made up of such grains fused together is sedimentary. Sedimentary rocks can be formed from the lithification of these buried smaller fragments (clastic sedimentary rock), the accumulation and lithification of material generated by living organisms (biogenic sedimentary rock - fossils), or lithification of chemically precipitated material from a mineral bearing solution due to evaporation (precipitate sedimentary rock).

Rocks are made of minerals, which are made of specific chemical elements. For example, the mineral quartz is made of the elements silicon and oxygen. The rock called granite consists mostly of the minerals quartz, feldspar and mica.

There are three main types of rock – Igneous, Sedimentary and Metamorphic.

Igneous rocks

Magma is a hot mix of melted minerals, and igneous rocks are formed when it cools. Cooling can happen quickly above ground to form volcanic rocks such as basaltrhyolite and andesite. Cooling can also happen slowly below the surface to form what are called plutonic rocks, such as granite.

Sedimentary rocks

On the surface of the Earth, the processes of weathering and erosion can break down any rock into small pieces called sediments. These sediments are carried away by water or wind and dumped somewhere else. The pebbles, sand and mud you find at the beach are sediments from broken down rock, transported there from somewhere else. Over a very long time, layers of sediment build up at the bottom of seas and lakes, squeezing water out of the layers beneath. Chemicals then cement the sediments into sedimentary rocks such as sandstone and mudstone. The remains of dead animals and plants often get trapped in sediments and can get turned into fossils by the same processes that turn sediments into rock.

Not all sedimentary rocks are made from broken pieces of other rocks. For example, limestone can be formed from the build-up of dead marine organisms on the sea floor or by chemical processes causing minerals to precipitate out of water.

Metamorphic rocks

The Earth’s crust is constantly, but slowly, on the move. Enormous forces push up, tilt, fold and break rocks. These processes can heat and squeeze any type of rock enough to change their structures. Such changes are called metamorphoses, and the resulting rocks are called metamorphic rocks. Marble is an example of a metamorphic rock – it is squashed and heated limestone. You may have come across the word metamorphosis before, because it is used to describe other types of change, such as a caterpillar changing into a pupa and then a butterfly.

There are parts of the Earth, called subduction zones, where the crust is carried deep inside. There is a subduction zone beneath the North Island of New Zealand. Deep down, any type of rock can melt into magma, which later cools to form igneous rock, continuing the rock cycle.

AKSHIT SEN, VII E            ROCK CYCLE: No rock stays the same forever. Over thousands and millions of years rocks are broken down,  oved around and deposited in different places. Rocks can be compacted together and pushed deep into the Earth where they are melted or deformed by intense heat and pressure only to be uplifted again to the surface. All of these processes combine to make the rock cycle   IGNEOUS ROCK : Deep in the earth's crust there are places where the rock has melted into magma which is a mixture of crystals and liquid rock. Sometimes the magma erupts out of the earth through a volcano and then it is called lava. When the lava cools and hardens on the earth's surface, it is called volcanic igneous rock. If the magma cools and hardens under the ground, it is called plutonic igneous rock. SEDIMENTARY ROCK: Wind and water cause erosion, breaking off pieces of rock and carrying them from one place to another. Gradually these pieces along with sand, pebbles, shells and plant matter gather into layers called sediment. Over a long period of time the sediment hardens into rock. That is how sedimentary rock is formed. Most of the rock on the earth's surface is sedimentary. METAMORPHIC ROCK :Just as cookie dough changes as it is baked, rock changes as it is heated, squeezed or both. Rocks deep within the earth are put through intense heat and pressure. In time, these forces change sedimentary or igneous rock into another type of rock called metamorphic rock.

Rock cycle: The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous.
Igneous rocks: Igneous rocks are rocks formed from molten magma. The material is made liquid by the heat inside the Earth's mantle . When magma comes out onto the surface of the Earth, it is called lava. Lava cools down to form rocks such as tuff and basalt.
Sedimentary rocks: Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.
Metamorphic rocks:
Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition.[1] The protolith may be a sedimentary, igneous, or existing metamorphic rock.

Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface.[2] They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction and distortion. Metamorphic rock can be formed locally when rock is heated by the intrusion of hot molten rock called magma from the Earth's interior. The study of metamorphic rocks (now exposed at the Earth's surface following erosion and uplift) provides information about the temperatures and pressures that occur at great depths within the Earth's crust.

There is a kind of interchange in states of rocks from one type to the other. This interchange is called the rock cycle of the Earth's crust. Through this continuous process,older rocks are transformed into new rocks by means of erosion,deposition,

The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting detrital material deposited in marine or terrestrial basins.

Igneous rocks=

Igneous rocks are defined as types of rocks that are formed when molten rock (rock liquefied by intense heat and pressure) cools to a solid state.

Lava is molten rock flowing out of fissures or vents at volcanic centres when cooled they form rocks such as basalt, rhyolite, or obsidian.

Sedimentary rocks=Sedimentation is the combined name for all the processes that cause organic and mineral particles to get settle. The particle that helps in forming the sedimentary rock is called sediment. Some examples of sedimentary rocks are:

Limestone

Chalk

Clay

Sandstone

Shale

Metamorphic rock=Metamorphic rocks are formed when rock changes over a period of time due to a lot of physical changes like pressure, heat and different chemical activity. When sedimentary rocks or igneous rocks go through the physical process such as pressure exposure, heat changes, and tectonic plate movement at plate edges. This rock changes occur when these rocks are exposed to an environment.

Rock cycle- Igneous rocks (primary rocks) are formed by the cooling and solidification of the magma in volcano. when the magma come out of the volcano and it cools down it becomes crystal and that is how igneous rocks are formed. Now when the time passes various weather agents like- wind, rain, glacier activities etc, acts on the igneous rocks and they slowly break down into sediments and then these small fragments are buried under many layers with time and pressure they turn into sedimentary rocks and this process is called lithification. The sedimentary rocks have the tendency to break apart into smaller sediments. There is metamorphosis in rocks especially when they are heated to 300 to 700 degree Celsius. In the earth there is tremendous amount of heat due to pressure. When earth's tectonic plate move around it produces heat. when the tectonic plates clashes it produces heat. The heat bakes the rocks.

Rock cycle :
1. Primary rocks are igneous rocks that are formed by cooling and solidification of magma into lava . Igneous rocks are formed depending on whether they cooled and solidified on or below the surface , they are extrusive and intrusive respectively. They have a crystalline structure.
Eg basalt ant tuff .

2. Sedimentary rocks : Due to the process of weathering  and erosion , rocks are broken down ,picked up,transported and then deposited by many various means - gravity, water, wind, sea waves and glaciers running down hill these broken rock material called sedmiment is spread and laid in low land , lakes and ocean beds and get deposited layer by layer overtime  and get compacted by the weight of over lying rocks and water into solid rocks .
Eg sandstone , lime stone

3. Metamorphic rocks : when igneous as well as sedimentary rocks , when subjected to immense heat pressure and weigh of overlying rocks , transformed or changed completely in their appearances, chemical properties and character which is know as metamorphic rocks.
Eg lime stone into marble and granite into gneiss.

The sediments get deposited layer by layer overtime, get compacted by the weight of overlaying rocks and water into solid rocks. Sandstone, shale clay, limestone, chalk, corals, gypsum, rocksalt and limestone are some examples of sedimetary rocks.

4. Metamorphic rocks : Igeneous as well as sedimentary rocks, when subjected to immense heat, pressure and weight of overlaying rocks, undergo changes in their appearences, chemical properties and character. They are transformed and changed completely. These rocks are called metamorphic rocks.

Rock cycle 

Rock is the process in which rock are continuously 
Transformered between three rock types 
Igneous , sedimentary ,  and metamorphic rock .

Igneous rocks- are formed by the cooling and solidification of magma into lava .

Sedimentary rocks - are the broken done by the wearing down of the earth surface .

It is the process by which rocks of one kind change into rocks of another kind.
There are three types of rocks 
1 Igneous rocks form when molten rock (magma or lava) cools and solidifies. 
2. Sedimentry rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. 
1 . Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.

This process of transformation of rocks from one to another is known as the rock cycle. When molten magma cools, it solidifies to become igneous rocks are broken down into smaller particles that are transported and deposited to form sedimentary rocks.

Rock Cycle:-
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. 


There are three types of rocks:-
1. Igneous rocks
2. Sedimentary rocks.
3. Metamorphic rocks. 

Igneous rocks:- 
Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. 
Example:- Pumice and Basalt.

Sedimentary rocks:- 
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation
Example:- sandstonenand limestone.

Metamorphic rocks:- 
Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism
Example:- quartzite and marble.

the rock cycle is a process in which rock are continuously transformed between three rock types igneous , sedimentary and metamorphic.  

There are three types of rock igneous rock , sedimentary rock and metamorphic rock 

Igneous rock - igneous rock are formed by cooling and solidification of magma into lava . These were the oldest rocks to be formed , so they are called ' primary rocks ' all other rocks are derived from igneous rocks . For example - Granite and Basalt

Sedimentar rock - sedimentary rocks are formed by sediment is deposited out of air , ice , wind , gravity , or water flows Carrying the particles in suspension . This sediment js often formed when weathering and erosion break down a rock in to loose material in a source area. They are also known as secondary rocks . The broken rock material caĺed sediment is spread and laid in lowlands , lakes and ocean bed .  For example- iron , ore , rock salt.

Metamorphic rock- igneous as well as sedimentary rock when subjected to immense heat , pressure and weight of overlying rocks undergo changes in their appearances , chemical properties and character. They are transformed or changed completely. 
Rock formed in this manner  are called metamorphic rock , for instance Limestone ( sedimentary ) would change in to marble  ; granite ( igneous) would with small rock . They are also known are secondary rock .

1. Igneous Rocks = These rocks are formed from the volcanic magma. When the molten magma cools, it becomes Igneous rocks. These rocks are also known as primary rocks or volcanic rocks.
Example: granite, basalt .

2. Sedimentary rocks= Rocks roll down, crack, and hit each other and are broken down into small fragments. These smaller particles are called sediments. These sediments are transported and deposited by wind, water etc . These loose sediments are compressed and hardened to form layers of rocks. These types of rocks are called sedimentary rocks. 
For example: sand stone, corals.

3. Metamorphic Rocks= They are formed when Igneous rocks and Sedimentary rocks are subjected to immerse heat pressure and weight overlying rocks under changes in their appearance chemicals they are transformed or changed.
For example: limestone would change into marble, granite would change into gneiss.

The earth crust is made up of the solid material called rocks that constitute 1% of its weight
Igneous rocks:- igneous rocks are formed by the cooling of magma into lava,these are the oldest rocks,ex=granite and basalt.
Sedimentary rock= in this rocks are broken down by the wearing down of the earth's surface,ex= limestone,sandstone,shale,clay, chalk,corals,gypsum and rocksalt.
Metamorphic rock= when the subjected to intense heat ,pressure and weight of overlying rocks, undergo changes in thier appearance, chemical properties and character, they are transformed or changed completely , ex= marble,granite would  change into gneiss after metamorphism.

The rock cycle gives us an idea of the origin of each rock and the role of the geological process that help in the transformation. Through this process the older rocks are transformed into new rocks by going through process like erosion, deposition, pressure, melting and cooling. It is a non stop process by which rocks are formed, destroyed and formed again. 

Eg: 
Metamorphic rocks undergo weathering, erosion, deposition and compacted to form sedimentary rocks.

Igneous and sedimentary rocks when subjected to immense heat and pressure, undergo changes in their appearances, chemical properties and character. And are transformed to metamorphic rocks.

*The process of transformation of rocks from one to another is known as the rock cycle.

-Igneous Rocks
Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface. The magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of  the atmosphere.

-Sedimentary Rocks
lithification of sediment takes place after the sediment has been deposited and buried. Fluids flowing through the rock and organisms may precipitate new minerals in the pore spaces between grains to form a cement that holds the sediment together.

-Metamorphic Rocks 
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. ... Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting material deposited in marine or terrestrial basins.
Conversion to metamorphic rocks requires conditions of increased temperature and/or increased pressure, conversion to sedimentary rocks occurs via the intermediate stage of sediments, and conversion to igneous rocks occurs via the intermediate stage of magma:
Magma is produced when rocks are melted. This melting can occur when a tectonic plate descends into the Earth’s crust at a  zone, or when a mid-ocean ridge opens up and produces decompression melting under the ridge. When the magma solidifies, it becomes an igneous rock.
And then the cycle continues...

1-The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another. Plate tectonic activity, along with weathering and erosional processes, are responsible for the continued recycling of rocks.


2-The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.



3-Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. ... All igneous rocks start out as melted rock, (magma) and then crystallize, or freeze.

TYPES OF ROCKS

Indigenous rocks-the indigenous rocks form when the molten lava cools and solidifies.e.g -granite,diorite

Sedimentry rocks-Sedimentry rocks are made up of pieces known as clasts of pre existing rocks.they are loosened by weathering.a broken rock material known as sediment get deposited layer by layer in the rock.e.g sandstone,shale

metamorphic rocks-Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

The three main rock types are igneous, sedimentary, and metamorphic. Crystallization, erosion and sedimentation, and metamorphism transform one rock type into another or change sediments into rock. The rock cycle describes the transformations of one type of rock to another
1. Igneous Rock 
These rocks are formed from the volcanic magma. When the molten magma cools, it becomes igneous rocks. These rocks are also known as Primary Rocks or volcanic rocks 
Example :- Granite , Basalt. 

2.Sedimentary Rocks 
These rocks are formed by deposition of sediments. When the rocks break down, the small fragment is transported by wind and get compressed and hardened to form sedimentary rocks. 
 Example- shale, Limestone, 
 
·3. Metamorphic Rocks 
These rocks are formed by heat, pressure and other chemical reactions. They are formed from igneous or sedimentary rocks. In a process called metamorphism. 
Example- clay, changing to slate, limestone, changing to marble etc..
Rock Cycle 
1-    Rocks come from lava and go back to lava through a process called the rock cycle. 
2-    When molten magma cools, it solidifies and forms igneous rock. 
3-    These igneous rocks are broken down into small piece. It is transported and deposited to form sedimentary rock. 
4-    When sedimentary and igneous rocks are subjected to heat and pressure, they form metamorphic rocks. 
5-    The metamorphic rocks which are still under great heat and pressure meltdown to form molten magma. 
6-    This molten magma again cools down and form igneous rock.

Rock cycle- The process of transformation of rocks from one type to another, due to changes in certain conditions in a cyclic manner, is called a rock cycle.

The earth’s crust is made up of various types of rocks. Any natural mass of mineral matter that makes  up the earth’s crust is called a rock. Rocks can be of different colour, size and texture. There are three major types of rocks: 

1. Igneous rocks: When the molten magma cools and gets into lava , it becomes solidified.
Rocks thus formed are called igneous rocks. They are
also called primary rocks. Depending on whether they cooled and solidified on or below the earth's surface, there are two types of igneous
rocks, extrusive rocks and intrusive rocks respectively. Example- Granite and Basalt. 

2. Sedimentary rocks: Rocks roll down, crack, and hit each other and are broken down into small fragments. These smaller particles
are called sediments. These sediments are transported
and deposited by wind, water, etc. These loose sediments are compressed and hardened to form layers of rocks. These types of rocks are called sedimentary rocks. For example, sandstone

Metamorphic rocks: Metamorphic rocks: Igneous rocks and sedimentary rocks when subjected to high heat, pressure and weight of underlying rocks, undergo changes in their appearance, chemical properties and characters. They're transformed completely. Rocks formed in this manner are called metamorphic rocks. For example- Limestone (sedimentary) would change into marble, granite (igneous) would change into gneiss after metamorphosis.

As we know that one type of rock
changes to another type under certain conditions in a cyclic manner and this process of transformation of the rock
from one to another is known as the rock cycle. 

When the
 molten magma cools, it solidifies
 to become igneous rock. These igneous rocks are broken down
  into small particles that are
transported and deposited to
form sedimentary rocks. When
the igneous and sedimentary
rocks are subjected to heat and pressure they change into metamorphic rocks. The metamorphic rocks which are still
under great heat and pressure
melt down to form molten magma. This molten magma again can
cool down and solidify into
igneous rock.

Rocks are classified into three categories which varies in different colors ,shapes and sizes. It is a concept used to explain how the three basic rock types are related and how the Earth processes, over geologic time, to change a rock from one type to another.

1) Igneous rocks
Igneous rocks are formed by the cooling and solidification of Magma into Lava. These were the oldest rocks to be formed, so there are also called 'primary rocks.

2) Sedimentary rocks
Rocks are broken down by the wearing down of earth surface also known as the process of weathering or erosion. The sediments get deposited layer by layer over time and get compacted by the weight of overlying rocks and water into solid rocks.

3) Metamorphic rocks
Igneous as well as Sedimentary rocks, when subjected to immense heat, pressure and weight of overlying rocks, undergoes changes in their appearances, chemical properties and character. Rocks formed in this manner is called metamorphic rocks

1. The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. ... Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting detrital material deposited in marine or terrestrial basins.
2. Types of rock
1. Igneous rocks- Also known as magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
2. Sedimentary rocks- are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.
3. Metamorphic Rocks- Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure, causing profound physical or chemical changes.

Igneous Rocks Turn Into Sedimentary Rocks Because When Weathering Agents Break Down The Rock They Turn Into Sediments Those Sediments Compress Over The Years And Turn Into Sedimentary rocks

Sedimentary Or Igneous Rocks Can Also Turn Into Metamorphic Rocks When They Are Between Pressure And Heat (Mostly In The Earths Core) .

Metamorphic Rocks Later Might Turn Into Magma And Spew Out Of Volcano And When The Lava Cools Down They Turn Back Into Igneous Rocks

The Rock cycle :- 
It is a concept used to explain how the three basic rock types are related and how the Earth processes, over geologic time, to change a rock from one type to another.

1) Igneous rocks :- Igneous rocks are formed by the  cooling and solidification of magma into lava. These were the oldest rocks to be formed, so they are alsocalled primary rock All other rocks are derived from Igneous rocks. Granite and basalt are examplesof igneous rocks.Igneous rocks may be formed by cooling on or below the Earth's surface Depending on whether they cooled and solidified on or below the Earth's surface, they are called extrusive and intrusive rocks, respectively. Either way, they have a crystalline structure.

2) Sedimentary rocks :- Rocks are broken down by the wearing down of the Earth's surface. We call these processes weathering and erosion. The broken material is dislodged, picked up, transported and then deposited by various means-gravity, water and glaciers running downhill, wind and sea waves.The broken rock material called sediment is spread and laid in lowlands, lakes and ocean beds. The sediments get deposited layer by layer over time, get compacted by the weight of overlying rocks and water into solid rocks. Sandstone, shale clay, limestone, chalk, corals, gypsum, rocksalt and limestone are some examples of sedimentary rocks.Sometimes, remains of animals and plants get trapped in the layers of sedimentary rocks. They are called 'fossils. Coal and petroleum were formed when remains of vegetation and animals were buried within layers of other sediments,

3) Metamorphic rocks:- Igneous as well as sedimentary rocks, when subjected to immense heat, pressure and weight of overlying rocks, undergo changes in their appearances, chemical properties and character. They are transformed or changed completely.Rocks formed in this manner are called metamorphic rocks. For instance, limestone (sedimentary) would change into marble; granite (igneous) wouldchange into gneiss after metamorphism. It may take millions of years for these changes to occur. In case, the original rock melts in the process, it becomes an igneous type.

There are three types of rocks 
1) Igneous rocks 
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.

2) Sedimentary rocks 
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.

3)Metamorphic Rocks

Earth processes, over geologic time, change a rock from one type into another.
Plate tectonic activity, along with weathering and erosional processes, are
responsible for the continued recycling of rocks.

 Igneous Rocks- Igneous rocks form when hot, molten rock crystallizes and
solidifies. The melt originates deep within the Earth near active plate
boundaries or hot spots, then rises toward the surface.
 
 Sedimentary
Rocks- These rocks often start as sediments carried in
rivers and deposited in lakes and oceans. When buried, the sediments lose water
and become cemented to form rock. 
 
 Metamorphic Rocks- Metamorphic Rocks are formed from other rocks that are
changed because of heat or pressure. They are not made from molten rock – rocks
that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the
rocks are heated and put under great pressure .

There are three types of rocks :
Igneous rocks: When magma is sent into the earth's surface , it cools and forms igneous rocks .
Sedimentary rocks: Igneous rocks break's into small pieces called as sediment , after some years a sedimentary rock is formed .
Metamorphic rocks: When sedimentary rocks goes in the earth's crust and heat is high then a metamorphic rock is formed .
Like this the process goes on .

                         Sedimentary Rocks
Rocks are broken down by the wearing down of the Earth’s surface. We call these processes weathering and erosion. The broken material is dislodged, picked up, transported and then deposited by various means – gravity, water and glaciers running down hill, wind and sea waves. CHALKS and CORALS are examples sedimentary rock.

The Rocks are of three types due to their 'COLOUR, SIZE, TEXTURE and CHEMICAL COMPOSITION.

The types of rocks are:- 
1) Igneous Rocks -  Igneous rocks are formed by cooling and solidification of magma into lava. These were the oldest rocks to be formed, so they are also called 'Primary Rocks'. All  other rocks are derived from igneous rocks. Examples are Granite and Basalt. Igneous Rocks may be formed by cooling on below the Earth's surface. Depending on whether they cooled and solidified on or below the Earth's surface, they called extrusive and intrusive rocks, respectively. Either way they have a crystalline structure.

2) Sedimentary Rocks:- Rocks are broken down by the wearing down of the Earth's surface. We call these processes weathering and erosion. The broken material is dislodged, picked up, transported and then deposited by various means ----- Gravity, Water and Glaciers running downhill, wind and sea waves. The broken rock material called sediment is spread and laid in lowlands, lakes and ocean beds. The sediments get deposited layer by layer over time, get compacted by the weight of overlying rocks and water into solid rocks. Sandstones, Shale clay, Limestone, Chalk, Corals, Gypsums, Rock salt  are example of sedimentary rocks. Sometimes the remains of animals and plants get trapper in the layer of sedimentary rocks and are called 'Fossils'. Coal and Petroleum were formed when remains of vegetation and animals were buried within layers of other sediments.

3) Metamorphic Rocks:- Igneous as well as sedimentary rocks when subjected to immense heat, pressure and weight of overlying rocks, undergo changes in their appearances , chemicals properties and character. They are transformed or changed completely. Rocks formed in this manner are called metamorphic rocks. For instance, Limestone (Sedimentary) would change into marble and Granite (Igneous) would change into gneiss. It may take millions of years to occur.

                 Rock Cycle

Metamorphic rocks are not only subjected to change under heat an pressure, they may be weathered, eroded, deposited and compacted to form sedimentary rocks. There is a kind of interchange in the state of rocks from one type to the other type of the Earths crust. Through this process, older rocks are transformed into new rocks by means of erosion, deposition, pressure, melting and cooling. It is an endless process.
The process when one kind of rock is changed to another type of rock is called Rock Cycle.

Metamorphic rocks are not only subjected to change under heat and pressure, they may be weathered, eroded, deposited and compacted to form sedimentary rocks. There is a kind of interchange in the state of rocks from one type to the other. This interchange is called the rock cycle of the Earth's crust. Through this continuous process, older rocks are transformed into new rocks by means of erosion, deposition, pressure, melting and cooling. The rock cycle gives us an idea of the origin of each rock and the role of geological processes in transforming one rock type into another. It is an endless process by which rocks are formed, destroyed and formed again.

There are 3 types of rock:
1. Igneous rock - This rock is made when a volcano erupts the magma also called lava comes out and after some time it cools down and takes form of a black crystal. Some examples are bastal and granite.
2. Sedimentary rocks - So, this rock is formed when the dead animals and plants and rocks stack and stack on each other it forms a hard rock. Some examples are sandstone and limestone
3. Metamorphic rock - This rock depends on sedimentary rock as when the pressure of sediments and the heat of magma increase the other rocks changes their forms suppose clay to slate and shale to phyllite. 
Rock cycle 
As we know that these all rocks depend on each other if igneous rock won't exist so other to rocks also won't exist. When igneous rock breacks and becomes sediment so sedimentary rock forms and when sedimentary rock breaks and gives pressure to metamorphic rock so it forms. So we can simply conclude that these three depends on each other.

1) Igneous rocks
Igneous rocks are formed by the cooling and solidification of Magma into Lava. These were the oldest rocks to be formed, so there are also called 'primary rocks.
For example=Basalt and Granite
2) Sedimentary rocks
Rocks are broken down by the wearing down of earth surface also known as the process of weathering or erosion. The broken Rock material left is known as sediment which is spread and laid in lowlands lakes and even Ocean beds. The sediments get deposited layer by layer over time and get compacted by the weight of overlying rocks and water into solid rocks.
For example=sandstone and limestone
3) Metamorphic rocks

There are three Types of Rocks.
1 - Igneous Rocks - Igneous rocks form when molten rock (magma or lava) cools and solidifies.
2 - Sedimentary Rocks - Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. 
3 - Metamorphic Rocks - Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.

Rock Cycle 
The transformation of one type of rock into another, under certain conditions and in a cyclical manner is referred to as the rock cycle. For example, igneous rocks, formed as a result of the solidification of molten magma, may break down into small particles, which may then be transported and deposited to form sedimentary rocks. Sedimentary and igneous rocks transform into metamorphic rocks when subjected to heat and pressure. These metamorphic rocks may themselves get broken down to form sedimentary rocks, or they may melt under great heat and pressure to form molten magma, which would then once again solidify to form igneous rocks.

Metamorphic rocks- Igneous rocks as well as the sedimentary rocks, under go changes in ther apearences,chemical properties and caracter. They are transformed   or changed completely.Rocks formed in this manner are called metamorphic rocks. For instance, lime stone would change into marble;Granite would change into geneiss After metamorphism.

2- Sedimentary Rock- These rocks are broken down by the wearing of the Earth's surface. The broken material is deposited by various means like gravity, water and glaciers. Then the broken Rock material called Sediment is spread and laid in lowlands, lakes. Then the sediment got deposited layer by layer over time and get compact by the weight of overlying rocks. Examples- Limestone, chalk. 

3- Metamorphic Rock- Igneous and sedimentary rocks, when subjected to immense heat, pressure and weight of overlying rocks, undergo changes it appearances, chemical properties and character. They are transformed or changed completely. Examples- Marble, slate.

The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.

There are three kinds of rocks: igneous, sedimentary, and metamorphic.
Igneous Rocks

    Igneous rocks are formed from melted rock deep inside the Earth.
    Igneous rocks are formed in molten magma.
    Igneous rock are formed when magma cools and crystallizes into a rock formation.
    Most of the earth's crust is made out of igneous rock.
    Many mountains are made out of igneous rocks.

Sedimentary rocks

    Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons.
    Sedimentary rocks cover most of the Earth's rocky surface, but they only make up a very small percentage of the planet's crust.
    They often contains fossils of plants and animals millions of years old.

Metamorphic rocks

    Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
    Metamorphic rocks can be formed by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
    Metamorphic rocks were once igneous or sedimentary rocks, but have been changed as a result of intense heat and/or pressure within the Earth's crust.

THERE ARE THREE TYPES OF ROCKS -
IGNEOUS ROCKS-Igneous rocks are formed by the cooling and solidification of magma into lava . EX- Granite and Basalt 

SEDIMENTARY ROCKS-    formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, follwed by cementation. 

METARMORPHIC ROCKS- Igneous as well as sedimentary rocks,when subjected to immense heat,pressure and weight of overlying rocks,undergo changes in thier appearances,chemical properties and character. 

Rock Cycle- Metamorphic rocks are not only subjected to change under heat and pressure,they may be weathered ,eroded,deposited and compacted to from sedimentary rocks.There is a kind of interchange in state of rocks from one type to the other . This interchange in state of rocks is called rock cycle of earths crust.Through this continous process,older rocks are transformed into new rocks by erosion ,depsition,pressure,melting and colling

Rock cycle :- The process of transformation of rocks from one form to an other in a cyclic manner is known as the rock cycle. It includes the following processes: Hot lava cools down to form igneous rocks. ... When these igneous and sedimentary rocks are subjected to great heat and pressure, they change into metamorphic rocks.

1. Igneous rocks - It is form when molten rock (magma or lava) cools and solidifies. For example - 

2. Sedimentary rocks - It is originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.  For example-

3. Metamorphic rocks - result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust. For example -

Rock cycle: 
There is a kind of interchange in the state of rocks from one type to the other.This interchange is called the rock cycle of the Earth's crust. Through this continuous process, older rocks are transformed into new rocks by means of erosion deposition, pressure, melting and cooling. The rock cycle gives us an idea of the origin of each rock and the role of geological processes in transformed one rock type into another.
Types of rocks:-
1)Igneous rocks: This are formed by the cooling and solidification of magma into lava. Igneous rocks may be formed by cooling on or below the earth's surface.These were the oldest rocks to be formed, so they are also called 'primary rocks'.
Ex: Granite and Basalt
2) Sedimentary rocks: Rocks are broken down by the wearing down of the Earth's surface. We call these processes weathering and erosion. The broken rock material called sediment is spread and laid in lowlands, lakes, and ocean beds.
Ex: Sandstone, limestone and chalk.
3) Metamorphic rocks: lgneous as well as Sedimentary rocks, when subjected to immerse heat, pressure and weight of overlying rocks, undergo changes in their appearances, chemical properties and character. Rocks formed in this manner are called metamorphic rocks. 
Ex: Quartzite and slate.

The three types of rocks are Igneous , sedimentary and metamorphic rocks.
Igneous Rocks - These are the primary rocks formed by the cooling of lava.
eg- granite, basalt etc.
Sedimentary rocks - these are the secondary rocks formed when the sediment and small pieces of igneous rocks gets buried in the earths surface.
eg- limestone, sandstone etc.
Metamorphic rocks - These are secondary rocks formed when sedimentary rocks undergo extreme heat and pressure.
eg- copper, iron etc.
Rock Cycle
When the magma comes out and cools down the igneous rocks are formed. Then when the igneous rocks break in small pieces and get buried in the earth's surface then the sedimentary rocks are formed. After that when the sedimentary rocks undergo high heat and pressure then the  metamorphic rocks are formed. At last when the metamorphic rocks melt then again the magma is formed. Like this the whole process works.

2)Sedimentary rock - sedimentary rock are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface

There are mainly four ways to form sedimentary rocks

1) Deposition of weathered remains of other rocks
2)Deposition of the results of biogenic activity
3)Percipation from solution
4)Accumulation and the consolidation of sediments

Eg. Sandstone , Limestone

3)Metamorphic rock - Metamorphic rocks are formed by the process of metamorphism , they are formed when the rock changes over a period of time due to a lot of phisycal changes , pressure and physical or chemical changes 

Eg. Slate , Marble

First magma comes out of a volcano as lava
Then it cools down and becomes igneous rocks
After that igneous rocks break into sediments
Then the sediment gets buried under layers of soil and turn into sedimentary rocks
Finally the sedimentary rocks undergo pressure from the earth's core and turn into metamorphic rocks

2.Sedimentary Rock-This type of rock is formed when the sediments of igneous rocks are deposited on the bed of a river or sea then cemented and sticks together to form a sedimentary rock. ex-Sandstone, Limestone and etc.
3.Metamorphic Rock-This type of rock is formed by the process  of metamorphosis. In this process the sedimentary or igneous rock is pressurized and baked at the same time. This type of rock is found near lava or very deep inside the Earth. ex-Marble, Gneiss, Granulite and etc.

The types of Rocks:
1. Igneous Rocks: Igneous rocks are defined as types of rocks that are formed when molten rock (rock liquefied by intense heat and pressure) cools to a solid state. They are also known as Primary Rocks. For Example: Obsidian, Andesite, Basalt.
2. Sedimentary Rocks: Sedimentary rocks are formed by the deposition and subsequent cementation on the material at the Earth’s surface within the bodies of water. These rocks are formed in four ways:
1.      Deposition of weathered remains of other rocks
2.     Accumulation and the consolidation of sediments
3.     Deposition of the results of biogenic activity
4.    Precipitation from solution.
Some Examples of Sedimentary Rocks are Shale, Limestone and Clay
3. Metamorphic Rocks: Metamorphic rocks are formed when rock changes over a period of time due to a lot of physical changes like pressure, heat and different chemical activity. When sedimentary rocks or igneous rocks go through the physical process such as pressure exposure, heat changes, and tectonic plate movement at plate edges. This rock changes occur when these rocks are exposed to an environment. For example: Gneiss, Quartzite, Slate.

The Rock Cycle:
The rock cycle is a series of processes that create and transform the types of rocks in Earth’s crust. There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle.

Rock Cycle:-
There is a kind of interchange in the state of rocks from one type to the other. The process of transformation of rocks or the interchange of rocks is called the Rock Cycle.

The three types of rocks and the process which lead to their transformation are :-

1. Igneous Rocks :
 These rocks are formed by the cooling and solidification of magma into lava. These were the oldest rocks to be formed. These rocks are also called the 'primary rocks'. Example - Granite , basalt.  These rocks are also formed by cooling on or below the Earth's surface. They are also called Extrusive and intrusive rocks. They have a crystalline , fine-grained structure. 

2. Sedimentary rocks : 
These rocks are broken down by the wearing down of the Earth's surface. These processes are called weathering and erosion. The broken material is dislodged, picked up, transported and then deposited by various means-gravity, water and glaciers running downhill, wind and sea waves.
The broken rock material called sediment is spread and laid in lowlands, lakes and ocean beds. The sediments get deposited layer by layer over time, get compacted by the weight of overlying rocks and water into solid rocks. Some examples of Sedimentary rocks are Sandstone, limestone, chalk , rock salt , corals etc.

3. Metamorphic rocks: 
Igneous as well as sedimentary rocks, when subjected to immense heat, pressure and weight of overlying rocks, undergo changes in their appearances, chemical properties and character. They are transformed or changed completely.
Rocks formed in this manner are called metamorphic rocks. For instance, limestone (sedimentary) would change into marble; granite (igneous) would change into gneiss after metamorphism. It may take millions of years for these changes to occur. In case, the original rock melts in the process, it becomes an Igneous type.

The transformation of old rocks into new rocks in the means of erosion, weather etc. is called rock cycle.
The 3 types of rocks and their formations are
1.Igneous rocks - When magma (Lava in the volcano) is solidifized (freezed) then it forms a rock called igneous rocks.
2.Sedimentary rocks: Rocks which are broken down by wearing down of Earth's surface. These broken rocks are called sediment, when sediment goes into water due to gravity etc. it becomes a rock 
which is called a sedimentary rock.
3.Metamorphic rocks: when these rocks are put to heat or pressure they are transformed into new rocks named metamorphic rocks

EXAMPLE:- Granite and Basalt

Sedimentary rocks- Sedimentary rocks cover most of the Earth’s rocky surface, but they only make up a very small percentage of the planet’s crust. Rocks broken down by the wearing down of Earth's surface by process of weathering and erosion. The broken rock material called sediment is deposited by various means such as water, wind, and sea waves and laid in lakes and ocean beds. They get compacted into solid rocks by weight of overlying rocks and water. They often contains fossils of plants and animals millions of years old.
EXAMPLE:- Chalk and Limestone

Metamorphic rocks-In these rocks, metamorphic minerals are easily visible by eye or hand and the mineral grains have a highly orientated fabric. Igneous as well as sedimentary rocks when subjected to immense heat , pressure and weight of overlying rocks undergo changes in their appearances, chemical properties and character.  For example: Limestone (sedimentary) would change into marble ; Granite (igneous) would change into gneiss after metamorphism .

The three main rock types are igneous, sedimentary, and metamorphic. Crystallization, erosion and sedimentation, and metamorphism transform one rock type into another or change sediments into rock. The rock cycle describes the transformations of one type of rock to another.

1. Igneous Rocks:
Ans. Igneous Rock is formed through the cooling and solidification of magma or lava. Eg: Granite

2. Sedimentary Rocks:
Ans. Sedimentary Rocks are formed by the accumulation deposition of mineral or organic particles at the earth surface. Eg: Linestone

3. Metamorphic Rocks:
Ans. Metamorphic Rocks arise from the transformation of a existing rocks to a new types of rock. Eg: Marble

1.Igneous rocks are more than just  a cool name. They’re actually cool in another way.

2.Sedimentary rocks are formed at the surface of the Earth. This can take place either in water or on land.

3. Metamorphic rocks are characterized by their distinctive mineral composition and texture. Because every mineral is stable only within certain limits, the presence of certain minerals in metamorphic rocks indicates the approximate temperatures and pressures at which the rock underwent metamorphosis.

    Igneous Rocks : These are formed by the cooling and solidification of magma into lava. Igneous rocks may be formed by cooling on or below the earth's surface . EG: Granite and Basalt 
    Sedimentary Rocks : Rocks broken down by the wearing down of Earth's surface by process of weathering and erosion. The broken rock material called sediment is deposited by varipus means such as water, wind, and sea waves and laid in lakes and ocean beds. They get compacted into solid rocks by weight of overlying rocks and water . Eg: Sandstone,  limestone,  chalk, shale etc 
    Metamorphic Rocks : Igneous as well as sedimentary rocks when subjected to immense heat , pressure and weight of overlying rocks undergo changes in their appearances, chemical properties and character.  For example: Limestone (sedimentary) would change into marble ; Granite (igneous) would change into gneiss after metamorphism . 

The Rock Cycle :- 
☆There is a kind of interchange in the state of rocks from one type to the other . This interchange is called the Rock Cycle of the Earth's  crust  . 
☆ It is an endless process by which rocks are formed, destroyed and formed again .

Types Of rocks:
1.igneous rocks-igneous rocks are formed by cooling and solidification of magma into lava. the were the first type of the rocks to be formed so they are also referred as 'primary rocks'. all the rocks are derived from igneous. eg for igneous-granite and basalt

2.sedimentary rocks-rocks which are broken down by wearing down of earths surface. this process is known as weathering and erosion. example-limestone , chalk etc.

3.metamorphic rocks-igneous and sedimentary when subjected to immense heat , pressure and weight of overlying rocks , undergo changes in their appearance , chemical properties and character. they are changed completely. rocks which are formed in this manner are called metamorphic rocks eg. limestone will change into marble

The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Rock Cycle:-
This is a kind of interchange in the state of rocks from one type to the other. Through this continuous process, older rocks are transformed into new rocks by means of erosion, deposition, pressure, melting and cooling.

Types of Rocks:-
Igneous Rocks:- Igneous rocks are formed by the cooling and solidification of magma into lava. Igneous rocks may be formed by cooling on or below the Earth's surface. They have a crystalline structure. Ex- Granite, Basalt
Sedimentary Rocks:- Rocks are broken down by the wearing down of the Earth's surface. We call these processes weathering and erosion. The broken material is dislodged, picked up, transported and then deposited by various means- gravity, water and glaciers running downhill, wind and sea waves. Ex- Sandstone, Chalk
Metamorphic Rocks:- Igneous as well as sedimentary rocks, when subjected to immense heat, pressure and weight of overlaying rocks, undergo changes in their appearances, chemical properties and character. They are transformed of change completely. Ex- Limestone (sedimentary) to Marble

Rock Cycle:-
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.

There are three types of rocks:-
1. Igneous rocks
2. Sedimentary rocks.
3. Metamorphic rocks.

Igneous rocks:-
Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
Example:- Pumice and Basalt.

Sedimentary rocks:-
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation
Example:- sandstonenand limestone.

Metamorphic rocks:-
Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism
Example:- quartzite and marble.

There are three types of rock igneous rock , sedimentary rock and metamorphic rock

Igneous rock - igneous rock are formed by cooling and solidification of magma into lava . These were the oldest rocks to be formed , so they are called ' primary rocks ' all other rocks are derived from igneous rocks . For example - Granite and Basalt

Sedimentar rock - sedimentary rocks are formed by sediment is deposited out of air , ice , wind , gravity , or water flows Carrying the particles in suspension . This sediment js often formed when weathering and erosion break down a rock in to loose material in a source area. They are also known as secondary rocks . The broken rock material caĺed sediment is spread and laid in lowlands , lakes and ocean bed .  For example- iron , ore , rock salt.

Metamorphic rock- igneous as well as sedimentary rock when subjected to immense heat , pressure and weight of overlying rocks undergo changes in their appearances , chemical properties and character. They are transformed or changed completely.
Rock formed in this manner  are called metamorphic rock , for instance Limestone ( sedimentary ) would change in to marble  ; granite ( igneous) would with small rock . They are also known are secondary rock .

There are three types of rocks Igneous or Primary rocks, Sedimentary rocks and metamorphic Rocks also known as secondry Rocks.
1. Igneous Rocks = These rocks are formed from the volcanic magma. When the molten magma cools, it becomes Igneous rocks. These rocks are also known as primary rocks or volcanic rocks.
Example: granite, basalt .

2. Sedimentary rocks= Rocks roll down, crack, and hit each other and are broken down into small fragments. These smaller particles are called sediments. These sediments are transported and deposited by wind, water etc . These loose sediments are compressed and hardened to form layers of rocks. These types of rocks are called sedimentary rocks.
For example: sand stone, corals.

3. Metamorphic Rocks= They are formed when Igneous rocks and Sedimentary rocks are subjected to immerse heat pressure and weight overlying rocks under changes in their appearance chemicals they are transformed or changed.
For example: limestone would change into marble, granite would change into gneiss.

The rock cycle gives us an idea of the origin of each rock and the role of the geological process that help in the transformation. Through this process the older rocks are transformed into new rocks by going through process like erosion, deposition, pressure, melting and cooling. It is a non stop process by which rocks are formed, destroyed and formed again.

Eg:
Metamorphic rocks undergo weathering, erosion, deposition and compacted to form sedimentary rocks.

Igneous and sedimentary rocks when subjected to immense heat and pressure, undergo changes in their appearances, chemical properties and character. And are transformed to metamorphic rocks.

*The process of transformation of rocks from one to another is known as the rock cycle.

-Igneous Rocks
Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface. The magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of  the atmosphere.

-Sedimentary Rocks
lithification of sediment takes place after the sediment has been deposited and buried. Fluids flowing through the rock and organisms may precipitate new minerals in the pore spaces between grains to form a cement that holds the sediment together.

-Metamorphic Rocks
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. ... Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting material deposited in marine or terrestrial basins.

Conversion to metamorphic rocks requires conditions of increased temperature and/or increased pressure, conversion to sedimentary rocks occurs via the intermediate stage of sediments, and conversion to igneous rocks occurs via the intermediate stage of magma:
Magma is produced when rocks are melted. This melting can occur when a tectonic plate descends into the Earth’s crust at a  zone, or when a mid-ocean ridge opens up and produces decompression melting under the ridge. When the magma solidifies, it becomes an igneous rock.
And then the cycle continues...

1-The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another. Plate tectonic activity, along with weathering and erosional processes, are responsible for the continued recycling of rocks.

2-The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

3-Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. ... All igneous rocks start out as melted rock, (magma) and then crystallize, or freeze.

There Are Three Types Of Rocks  Igneous Or Primary Rocks, Sedimentary Rock And Metamorphic Rocks Also Known As Secondary Rocks

Igneous Rocks Turn Into Sedimentary Rocks Because When Weathering Agents Break Down The Rock They Turn Into Sediments Those Sediments Compress Over The Years And Turn Into Sedimentary rocks

Sedimentary Or Igneous Rocks Can Also Turn Into Metamorphic Rocks When They Are Between Pressure And Heat (Mostly In The Earths Core) .

Metamorphic Rocks Later Might Turn Into Magma And Spew Out Of Volcano And When The Lava Cools Down They Turn Back Into Igneous Rocks

in the rock cycle there are 3 types of rocks.rock cycle is the process where the rocks are made.

TYPES OF ROCKS

Indigenous rocks-the indigenous rocks form when the molten lava cools and solidifies.e.g -granite,diorite

Sedimentry rocks-Sedimentry rocks are made up of pieces known as clasts of pre existing rocks.they are loosened by weathering.a broken rock material known as sediment get deposited layer by layer in the rock.e.g sandstone,shale

metamorphic rocks-Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

Rock cycle
A Rock cycle has three stages based  on their mode of formation

Types of Rock

Indigenous rocks
They are fromed  by the cooling  of lava below of the earth surface or they can fromed after the solidification  and cooling of the magma lava into surface of earth after sometime when they are dried the turn into black crystal
Example
Granite , basalt

Sedimentary rocks
They are the rocks broken down by wearing down of earth surface we call these processes weathering and erosion ,the broken rock material is called sediment is speard and laid in lowlands lakes ocean neds , The sediments get deposited layer by layer over time and get compacted by the weight of overlying rocks
Exqmple
Limestone , corals

Metamorphic rocks
They are fromed when igneous rocks and sedimentary rocks are subjected to immense heat pressure and weight overlying rocks undergo changes in their appearance chemicals properties and characters they are transformed or changed
For example
Limestone would change into marble
Granite would change into gneiss

# data[].attributes.body
The three main rock types are igneous, sedimentary, and metamorphic. Crystallization, erosion and sedimentation, and metamorphism transform one rock type into another or change sediments into rock. The rock cycle describes the transformations of one type of rock to another
1. Igneous Rock

These rocks are formed from the volcanic magma. When the molten magma cools, it becomes igneous rocks. These rocks are also known as Primary Rocks or volcanic rocks
Example :- Granite , Basalt.

2.Sedimentary Rocks

These rocks are formed by deposition of sediments. When the rocks break down, the small fragment is transported by wind and get compressed and hardened to form sedimentary rocks.

Example- shale, Limestone,

·3. Metamorphic Rocks

These rocks are formed by heat, pressure and other chemical reactions. They are formed from igneous or sedimentary rocks. In a process called metamorphism.
Example- clay, changing to slate, limestone, changing to marble etc..
Rock Cycle
1-    Rocks come from lava and go back to lava through a process called the rock cycle.
2-    When molten magma cools, it solidifies and forms igneous rock.
3-    These igneous rocks are broken down into small piece. It is transported and deposited to form sedimentary rock.
4-    When sedimentary and igneous rocks are subjected to heat and pressure, they form metamorphic rocks.
5-    The metamorphic rocks which are still under great heat and pressure meltdown to form molten magma.
6-    This molten magma again cools down and form igneous rock.

Rock cycle- The process of transformation of rocks from one type to another, due to changes in certain conditions in a cyclic manner, is called a rock cycle.

The earth’s crust is made up of various types of rocks. Any natural mass of mineral matter that makes  up the earth’s crust is called a rock. Rocks can be of different colour, size and texture. There are three major types of rocks:

1. Igneous rocks: When the molten magma cools and gets into lava , it becomes solidified. Rocks thus formed are called igneous rocks. They are also called primary rocks. Depending on whether they cooled and solidified on or below the earth's surface, there are two types of igneous rocks, extrusive rocks and intrusive rocks respectively. Example- Granite and Basalt.

2. Sedimentary rocks: Rocks roll down, crack, and hit each other and are broken down into small fragments. These smaller particles
are called sediments. These sediments are transported
and deposited by wind, water, etc. These loose sediments are compressed and hardened to form layers of rocks. These types of rocks are called sedimentary rocks. For example, sandstone

3. Metamorphic rocks: Metamorphic rocks: Igneous rocks and sedimentary rocks when subjected to high heat, pressure and weight of underlying rocks, undergo changes in their appearance, chemical properties and characters. They're transformed completely. Rocks formed in this manner are called metamorphic rocks. For example- Limestone (sedimentary) would change into marble, granite (igneous) would change into gneiss after metamorphosis.

As we know that one type of rock changes to another type under certain conditions in a cyclic manner and this process of transformation of the rock from one to another is known as the rock cycle.

When the molten magma cools, it solidifies to become igneous rock. These igneous rocks are broken down   into small particles that are transported and deposited to form sedimentary rocks. When
the igneous and sedimentary rocks are subjected to heat and pressure they change into metamorphic rocks. The metamorphic rocks which are still under great heat and pressure melt down to form molten magma. This molten magma again can cool down and solidify into igneous rock.

Rocks are classified into three categories which varies in different colors ,shapes and sizes. It is a concept used to explain how the three basic rock types are related and how the Earth processes, over geologic time, to change a rock from one type to another.

1) Igneous rocks
Igneous rocks are formed by the cooling and solidification of Magma into Lava. These were the oldest rocks to be formed, so there are also called 'primary rocks.

2) Sedimentary rocks
Rocks are broken down by the wearing down of earth surface also known as the process of weathering or erosion. The sediments get deposited layer by layer over time and get compacted by the weight of overlying rocks and water into solid rocks.

3) Metamorphic rocks
Igneous as well as Sedimentary rocks, when subjected to immense heat, pressure and weight of overlying rocks, undergoes changes in their appearances, chemical properties and character. Rocks formed in this manner is called metamorphic rocks

1. The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. ... Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting detrital material deposited in marine or terrestrial basins.
2. Types of rock
1. Igneous rocks- Also known as magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
2. Sedimentary rocks- are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.
3. Metamorphic Rocks- Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure, causing profound physical or chemical changes.

Rock cycle--
The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another. Plate tectonic activity, along with weathering and erosional processes, are responsible for the continued recycling of rocks.
IGNEOUS ROCKS-
Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.
SEDIMENTARY ROCKS-
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.
METAMORPHIC ROCKS-
Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure, causing profound physical or chemical changes.

Igneous Rocks- Igneous rocks form when hot, molten rock crystallizes and
solidifies. The melt originates deep within the Earth near active plate
boundaries or hot spots, then rises toward the surface.

Sedimentary
Rocks- These rocks often start as sediments carried in
rivers and deposited in lakes and oceans. When buried, the sediments lose water
and become cemented to form rock.

Metamorphic Rocks- Metamorphic Rocks are formed from other rocks that are
changed because of heat or pressure. They are not made from molten rock – rocks
that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the
rocks are heated and put under great pressure .

Igneous rocks:- igneous rocks are formed by the cooling and solidification of magma into larva.

Sedimentary rocks:- Rocks are broken down by the wearing down of the earth’s surface.

Metamorphic rocks:- igneous as well sedimentary rocks When subjected heat pressure and weight of overlying rocks undergo changes in their appearances chemical properties and character.

The Rock cycle :-
It is a concept used to explain how the three basic rock types are related and how the Earth processes, over geologic time, to change a rock from one type to another.

1) Igneous rocks :- Igneous rocks are formed by the  cooling and solidification of magma into lava. These were the oldest rocks to be formed, so they are alsocalled primary rock All other rocks are derived from Igneous rocks. Granite and basalt are examplesof igneous rocks.Igneous rocks may be formed by cooling on or below the Earth's surface Depending on whether they cooled and solidified on or below the Earth's surface, they are called extrusive and intrusive rocks, respectively. Either way, they have a crystalline structure.

2) Sedimentary rocks :- Rocks are broken down by the wearing down of the Earth's surface. We call these processes weathering and erosion. The broken material is dislodged, picked up, transported and then deposited by various means-gravity, water and glaciers running downhill, wind and sea waves.The broken rock material called sediment is spread and laid in lowlands, lakes and ocean beds. The sediments get deposited layer by layer over time, get compacted by the weight of overlying rocks and water into solid rocks. Sandstone, shale clay, limestone, chalk, corals, gypsum, rocksalt and limestone are some examples of sedimentary rocks.Sometimes, remains of animals and plants get trapped in the layers of sedimentary rocks. They are called 'fossils. Coal and petroleum were formed when remains of vegetation and animals were buried within layers of other sediments,

3) Metamorphic rocks:- Igneous as well as sedimentary rocks, when subjected to immense heat, pressure and weight of overlying rocks, undergo changes in their appearances, chemical properties and character. They are transformed or changed completely.Rocks formed in this manner are called metamorphic rocks. For instance, limestone (sedimentary) would change into marble; granite (igneous) wouldchange into gneiss after metamorphism. It may take millions of years for these changes to occur. In case, the original rock melts in the process, it becomes an igneous type.
