Important things about rocks.

Igneous Rocks

• Igneous rock is formed when magma cools and hardens, can happen above or below the Earth's surface.
• There are over 700 types of Igneous rocks.
• Atoms and Molecules of melted materials form Magma.
• Examples of igneous rocks include basalt, granite, pumice, obsidian, tuff, diorite, gabbro and andesite.
• In conclusion, Igneous rocks are formed from volcanoes and heat.

In conclusion, Igneous rocks are formed from volcanoes and heat.

Metamorphic ROcks

• Metamorphic rocks have been changed over time by extreme pressure and heat.
• Weathering and erosion help bring metamorphic rock to the Earth's surface.
• 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.
• Examples of metamorphic rocks include anthracite, quartzite, marble, slate, granulite, gneiss and schist.
• In Conclusion, Metamorphic Rocks are formed by the mixing of rocks, along with heat and pressure.

MEtaMorphic

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

Sedimentary 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.

Sedimentary

• 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.

In Conclusion, Sedimentary Rocks are formed from sediments that are forced on top of each other, to create layers in the rocks we see today.
