The Rock Cycle

The Earth is a dynamic planet, and its rocks are constantly changing. The rock cycle shows how different natural processes transform rocks from one type to another.

All types of rock can be weathered, transported and cemented into layers to become sedimentary rock.

Under intense heat and pressure, any type of rock can be transformed to metamorphic rock.

When metamorphic rock is heated to its melting point and then cooled, it becomes igneous rock.
