The Rock Cycle

Igneous, Sedimentary, and Metamorphic Rock

How the Rock Cycle Works:

The basic idea of the rock cycle is explain how the different types of rock, igneous, sedimentary, and metamorphic are related to each other and how the Earth's processes help the rocks change into one another.

* Igneous rocks are formed when hot liquid rock called magma cools and solidifies.

* Metamorphic rocks are formed by the physical or chemical alteration by heat and pressure to become a denser form of rock.

* Sedimentary rocks are often formed when weathering and erosion break down a rock into loose material.
