The rock cycle is a geological model that describes the transformation of rocks from one type to another over time.
The formation of igneous rocks marks the beginning of the rock cycle. Once produced, igneous rocks are subjected to weathering and erosion.
Weathered and degraded particles, also referred to as sediment, are transported and deposited in layers by water, wind, and ice.
When exposed to heat and pressure, sedimentary and igneous rocks can experience metamorphism. This process results in the formation of metamorphic rocks.
Metamorphic rocks that are subjected to further temperature and pressure changes may recrystallize, resulting in the formation of new metamorphic rocks.
