How Is Rock Continually Recycled in the Rock Cycle

Magma is molten rock that exists below the surface. Most of it forms in the Earth's crust. Lava is magma that makes its way to the surface through volcanic activity or some other natural process. When molten rock cools, it hardens and becomes igneous rock. Basalt and granite are the two main types of igneous rock.
