Rocks are formed through various natural processes such as weathering, erosion or movement of tectonic plates. One type of rock gradually interchanges and recycles to form another type of rock. This change is called rock cycle. It is a very slow process.
♦ Solidification of molten magma produces igneous rocks.
♦ These igneous rocks break down due to natural forces and the sediments are transported from one place to another through air or water.
♦ The deposited sediments get compressed and form sedimentary rocks.
♦ When these rocks (igneous or sedimentary) experience high heat or pressure, they get converted into metamorphic rocks.
♦ And again, these metamorphic rocks under high heat and pressure melt to form molten magma.
♦ This way, the rock cycle continues.
