The rock cycle is a continuous process that describes how rocks change from one form to another over time. This cycle involves three main types of rocks: igneous, sedimentary, and metamorphic rocks, and it illustrates how they transform due to various geological processes.
Initially, igneous rocks form from the cooling and solidification of molten magma or lava. As these rocks are exposed to weathering and erosion, they break down into smaller particles, contributing to the formation of sedimentary rocks.
Once sediment accumulates and undergoes compaction and cementation, sedimentary rocks are created. These rocks can be transformed into metamorphic rocks when subjected to intense heat and pressure, usually due to tectonic activity.
Eventually, metamorphic rocks can melt back into magma, completing the cycle. Through this cycle, rocks are continuously modified and reshaped, demonstrating the dynamic nature of the Earth’s crust.
