Answer 2

Answer:

It is said that rock cycle has neither beginning nor end because when the magma cools down it forms igneous rocks,These igneous rocks further break down into sediments. These sediments form sedimentary rocks. These sedimentary rocks under tremendous heat and pressure form metamorphic rocks. These metamorphic rocks after thousands of years form magma and the cycle continues.
