What cycle does weathering, erosion, and deposition play a HUGE part in?
The Rock Cycle
_______ erupts from a volcano. As it cools, it becomes ________ rock. It experiences weathering, erosion, and deposition to become sediment. When the sediment is compacted, it become _________ rock. As it gets buried deeper, and experiences heat and pressure, it become ________ rock. That rocks melts and is turned back into magma.
Magma; igneous; sedimentary; metamorphic
