The Rock CycleThe Rock Cycle
A Cycle of Many PathwaysA Cycle of Many Pathways
KEY CONCEPT: Forces deep inside the Earth and at the surface produce a slow cycle that builds, destroys, and changes rocks in the crust.
◊ Igneous rock is turned into sediment by erosion. The sediment is deposited and slowly becomes sedimentary rock.
◊ The sedimentary rock is buried by more sediment and heat and pressure cause it to change into metamorphic rock.
◊ Metamorphic rock is forced into the mantle and melts forming magma. Magma erupts and cools to form igneous rock again.
