you can throw then they fall back down theres different types of rocks


WHAT I KNOW NOW

There are 3 different types of rocks 
Sedimentary
Igneous
Metamorphic
Each rock is made differently 
The oldest rock ever found is 4 billion years old
Some rocks are turned into jewlery
There are many different people who study rocks and the rock cycle like geologist, hydrologist, mineralogist, palaeontologist, sedimentologist.

in You can make ochre out of rocks that have iron oxide. They have to be soft and they are like the paint we use today. The aboriginals used it in their ceremonies and it was extremely useful for art and you can find it on the walls of cave in cave paintings.
WHAT I KNOW NOW IS,
Sedimentary rocks are formed by rocks that are weathered, the pieces of weathered rock travel to places like the mouths of rivers and form silt. The silt is layered up and compacts due to pressure that builds, getting the final result of rock. Igneous rocks are formed when hot rocks or magma/lava cool down and solidify, getting rock, igneous rock. Metamorphic rock is made when a pre-existing rock is metamorphisised or deformed due to intense heat under the ground. The metamorphic rocks can sometimes be seen on the earths surface. You can tell these different rocks apart by scratching them, looking at them and even licking them, a sedimentary rock often tastes like mud because it is silt that it is made of. Coal is a sedimentary rock, it is an organic sedimentary rock as it is made of rotting plant and animal material under the ground and through lots and lots of years forms coal. 
Emeralds are one of the most prized gemstones and are mainly found in Columbia and Brazil.  The ancient Egyptians used emeralds as jewellery but is not considered valuable by today's standards. 
Igneous rocks formed underground are called plutonic and above ground are called volcanic. Weathering is caused when wind, rain, water or hail weathers a rock down, a batholith that is exposed on the surface of the earth will be weathered down. Other then those ways of weathering there is actually more, a few others like, root wedging, when the wedge of a plant gets inside a crack of a rock and slowly grows, breaking apart the rock, and ice wedging, ice that forms in the cracks of rocks also expanding and breaking the rock, water expands 10% while frozen, also another is erosion which is a natural way of the rock breaking down.
I found out what an environmental geologist is, they are in charge of where people can put their mines and nuclear waste and nuclear power plants, though that is their job they also study the soil too, they are in charge of where the mines are put but the people who work at the mines burrow kilometres into the ground anyway and that absolutely cannot be good for the environment. ]]> 2019-04-29 01:26:54 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/354852395 cooper_wright_00 https://padlet.com/kieren_hume/mbon1021km39/wish/354852435 they are Heavy And Light

WHAT I KNOW NOW
I now know that there are 3 main types of rocks, metamorphic, sedimentary and igneous. I know that igneous rocks are formed from the cooling of magma or lava. Sedimentary rocks are formed from particles of other materials and mineral usually at the bottom of water forming together to create a rock. Metamorphic rocks are formed when rocks are put under extreme heat and pressure which causes the rock to change.

Rocks can contain meany different minerals. Rocks come in meany different shape and sizes.

WHAT I KNOW NOW

There are three different types of rocks
Igneous 
Metamorphic
Sedimentary

The oldest layer of sedimentary rock is at the bottom and the youngest is at the top. Sedimentary rocks are formed by sediments. 

Igneous rocks are formed through the cooling and  solidification of magma.

 Metamorphic rocks are formed under heat and pressure causing it to change  physically and chemically. ]]> 2019-04-29 01:27:25 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/354852506 https://padlet.com/kieren_hume/mbon1021km39/wish/354852516 blue bird is pink

WHAT I KNOW NOW
sedimentary rocks form layars at the bottom   of the ocean  Marble is a metamorphic rock formed when limestone is exposed to high heat and pressure within the Earth.  ores are rocks that contain minerals

Rocks are made of stone. Many kinds of stone exist, and many stones can contain metals. Stone can vary due to the height it was found on. Such as when a rock is found high up, it might be different than rocks below sea level. Rocks are pushed and pulled around by land erosion and land slip. Rocks are used to make gravel paths. Rocks are sometimes chewed on by animals so their teeth are cleaned and sharpened. The biggest rock is Ularu in the outback of Australia. Mountains can count as big rocks, but they are not officially rocks. Some trees grow off moss on rocks, and it looks like the tree is growing out of the rock. It is not, but it still looks pretty cool.]]> 2019-04-29 01:28:15 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/354852654 https://padlet.com/kieren_hume/mbon1021km39/wish/354852815 2019-04-29 01:29:02 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/354852815 jayme_king_00 https://padlet.com/kieren_hume/mbon1021km39/wish/354853024 The aboriginals tie rocks to the head of a stick to make a spear]]> 2019-04-29 01:29:45 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/354853024 flototron https://padlet.com/kieren_hume/mbon1021km39/wish/354853086 2019-04-29 01:30:01 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/354853086 https://padlet.com/kieren_hume/mbon1021km39/wish/354853508 rocks are made up of minerals and other rocks]]> 2019-04-29 01:32:06 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/354853508 https://padlet.com/kieren_hume/mbon1021km39/wish/354854099 Rocks come in different shapes and sizes

there are 3 different types of rocks sedimentary ,igneous and  metamorphic 
metamorphic rocks form are from high heat.
 Sedimentary rocks are formed by sediments.
 Magma is the heart of any igneous rock so  when magma cools, it turns into rock. 
THE ROCK CYCLE
melting metamorphic rock becomes magma.the cooling of magma makes igneous rock heat and pressure of igneous or sedimentary rocks makes metamorphic rocks.weathering and erosion of any of these rocks makes sediments.the compaction of sediment of course makes a sedimentary rock ]]> 2019-06-03 01:21:12 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/365171237 brayden_cunningha_00 https://padlet.com/kieren_hume/mbon1021km39/wish/365171373 BadboxJelly9
Rocks are made of a substance found in the earths mantle called magma. When magma cools it becomes an igneous rock. Igneous is Latin for born out of fire. Rocks can pick up traces of other minerals and metals that contaminate it and turn it into beautiful gemstones. Goes to show that imperfections can lead to beautiful things. Rocks will be eroded by water and rock slides and will follow the water streams to the ocean where they collect up as a new type of rock called sedimentary rocks. Sedimentary rocks are made of sand, dirt and other sediment of eroded rocks. This means they are the best form of fossil preservation because the way they form is gradual and graceful. These rocks can erode too, being driven beneath ground and half melted, then twisted, layered and changed into a metamorphic rock, a rock that has gone through dramatic change. These rocks can melt again, and cool to igneous rocks. When this happens it is called the rock cycle, because the igneous rock changes to sedimentary rock, then that changes to metamorphic, and then it goes back again. The rock cycle can also be done in different ways other than the simple cycle. Some rocks are different to others. They are made in different ways, with different materials. Obsidian is made by quick cooling magma. Sapphires are made when a rock cools with an iron contamination.]]> 2019-06-03 01:22:16 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/365171373 https://padlet.com/kieren_hume/mbon1021km39/wish/365171491 turtles
There are 3 different types of rocks, Sedimentary, Igneous & Metamorphic

Sedimentary rocks are formed from burial and compaction of sediments, or particles
Igneous rocks are formed when magma cools down
Metamorphic rocks are formed when a pre-existing rock gets deformed due to intense heat.  ]]> 2019-06-03 01:23:04 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/365171491 ashley_ayre_001 https://padlet.com/kieren_hume/mbon1021km39/wish/365172628 2019-06-03 01:31:24 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/365172628 flototron https://padlet.com/kieren_hume/mbon1021km39/wish/365172890 2019-06-03 01:33:55 UTC https://padlet.com/kieren_hume/mbon1021km39/wish/365172890 https://padlet.com/kieren_hume/mbon1021km39/wish/365172914 Their is 3 different types of rock, Metamorphic, Sedimentary and Igneous. There is also a chance that more exist in the rock cycle as we explore more. 

Ingenuous are made from lava, sedimentary are made from the ground pushing it up and metamorphic are sorta both.
