Three main rocks by Mind Map: Three main rocks

1. 1. Igneous Rock

1.1. Igneous rock (derived from the Latin word ignis meaning fire) 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. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks

2. Sedimentary Rock

3. How Igneous rocks are formed

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

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