Metamorphic Rock Facts

Enjoy our metamorphic rock facts for kids. Find interesting information and a range of examples that help explain what metamorphic rocks are and what makes them different from other kinds of rocks.

Metamorphic rocks have been changed over time by extreme pressure and heat.

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.

Uplift and erosion help bring metamorphic rock to the Earth's surface.

Examples of metamorphic rocks include anthracite, quartzite, marble, slate, granulite, gneiss and schist.

Anthracite is a type of coal with a high carbon count, few impurities and with a high luster (meaning it looks shiny).

Marble is a metamorphic rock that is formed from the sedimentary rock limestone.

Quartzite is a metamorphic rock that is formed from the sedimentary rock sandstone.

Slate is a metamorphic rock that is formed from the sedimentary rock mudstone.

Granulite is a metamorphic rock that is formed from the igneous rock basalt.

Sedimentary Rock Facts

Enjoy our sedimentary rock facts for kids. Find interesting information and a range of examples that help explain what sedimentary rocks are and what makes them different from other kinds of rocks.

Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans.

This sediment can include minerals, small pieces of plants and other organic matter.

The sediment is compressed over a long period of time before consolidating into solid layers of rock.

Sedimentary rocks forms layers called strata which can often be seen in exposed cliffs.

Sedimentary rocks cover the majority of the Earth's rocky surface but only make up a small percentage of the Earth's crust compared to metamorphic and igneous types of rocks.

Examples of sedimentary rocks include limestone, sandstone, mudstone, greywacke, chalk, coal, claystone and flint.

Limestone forms the metamorphic rock marble when subjected to extreme heat and pressure over time (metamorphism).

Sandstone forms the metamorphic rock quartzite.

Mudstone forms the metamorphic rock slate.

Chalk is a soft, white form of limestone.

Flint is a hard, sedimentary form of the mineral quartz.

Igneous Rock Facts

Enjoy our igneous rock facts for kids. Find interesting information and a range of examples that help explain what igneous rocks are and what makes them different from other kinds of rocks.

Igneous rock is formed when magma cools and solidifies, it may do this above or below the Earth's surface.

Magma can be forced into rocks, blown out in volcanic explosions or forced to the surface as lava.

The atoms and molecules of melted minerals are what make up magma.

These atoms and molecule rearrange themselves into mineral grains as the magma cools, forming rock as the mineral grains grow together.

There are over 700 different types of igneous rocks.

Examples of igneous rocks include basalt, granite, pumice, obsidian, tuff, diorite, gabbro and andesite.

Basalt forms the metamorphic rock granulite when subjected to extreme heat and pressure over time (metamorphism).

Granite is a common rock that contains at least 25% quartz and is sometimes used in construction because of its strength.

Pumice is an unusual, lightweight rock formed when molten rock is rapidly blown out of a volcano, forming bubbles as it quickly loses pressure and cools at the same time.

Obsidian is a volcanic glass that forms quickly without crystal growth, it can have very sharp edges making it useful as a cutting tool or arrowhead.

Tuff is a rock formed from volcanic ash.

The upper section of the Earth's crust is made up of around 95% igneous rock.
