The rock cycle is an integral aspect of Earth sciences that sheds light on Earth's age, history, and the forces that shape it. Understanding the rock cycle is key to discerning how rocks change forms, contributing to soil fertility, and providing resources like minerals and fossil fuels. It also has practical applications in …
