The rock cycle describes the way that rock material cycles through Earth's crust. All

rocks start out as lava or magma that cools into igneous rock. An igneous rock must then

be weathered into sediments for the next stage of the cycle. Sediments are compressed

and cemented to become sedimentary rock. Metamorphic rock forms when rocks are

heated and squeezed deep in Earth's crust. New igneous rock forms when metamorphic

rock is heated so much that it melts into magma, which cools into igneous rock. All rocks

go through this cycle over and over again.
