Rock Cycle Processes

The rock cycle is a natural process that describes how rocks change from one type to another over time. These changes happen through melting, cooling, weathering, erosion, compaction, cementation, heat, and pressure. The rock cycle is continuous, and rocks can move through i...

Different types of rocks form through different processes and can change into other types over time. The rock cycle explains how rocks form and change.

One way rocks change is through cooling and crystallization. Deep beneath the Earth’s surface, heat melts rock into magma. As it cools, it hardens into igneous rock. Slow cooling forms larg...
