Explanation:The rock cycle is a model that describes how rocks are created, changed, and broken down. There are three major types of rock: igneous rock, metamorphic rock, and sedimentary rock. During the rock cycle, each type of rock may be changed into another type.

The rock cycle includes these processes:

Crystallization is the process by which magma cools and forms solid igneous rock.

Heat and pressure can change igneous rock and sedimentary rock into metamorphic rock.

Weathering and erosion are the processes that break down rock into sediment and transport this sediment to other places.

Sediment is changed into sedimentary rock by compaction and cementation.

Melting is the process that transforms solid rock back into liquid magma.
