This article will help you to learn about the rock cycle with diagram. The change of one rock into another type under different conditions of heat, pressure, weathering and erosion is known as rock cycle. Initially, all minerals originated from igneous rocks. As soon as igneous rocks are exposed they are weathered and eroded by […]
