Rock formed from magma

IgneousMetamorphicSedimentary

Rock formed from the layering and cementing of sediments over time

Igneous MetamorphicSedimentary

Any rock type that undergoes great pressure and heat

Igneous MetamorphicSedimentary

How can rocks change over time?

Discussion

How do rocks recycle – why do we call how rocks form the rock cycle?
