The Rock Cycle
The rock cycle is a continuous process through which rocks change from one type to another over time. It involves three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from cooled molten lava, while sedimentary rocks develop from the accumulation and compression of sediments. Metamorphic rocks arise when existing rocks undergo intense heat and pressure, altering their structure. These rocks can be broken down into sediments, which may eventually form new rocks, completing the cycle. This process is driven by Earth's internal heat and surface conditions, highlighting the dynamic nature of our planet.

The Rock Cycle is a continuous process that describes how rocks change from one type to another over time. It involves three main types of rocks: igneous (formed from cooled lava or magma), sedimentary (made from compacted minerals and organic materials), and metamorphic (created when existing rocks are altered by heat and pressure). Through processes like erosion, melting, and uplift, rocks are transformed and recycled. For instance, sedimentary rocks can break down into sediments, which may eventually form new sedimentary rocks, while igneous rocks can be buried and changed into metamorphic rocks. This cycle illustrates Earth’s dynamic nature.
