Question

What do you know about the rock cycle? Explain with a help of a diagram.

Answer 1

Ans. Rocks go through a continuous process of change or transformation. It begins with formation of igneous rocks due to the cooling down and solidification of the hot molten magma which reaches the earth's crust. the rocks are then broken down into smaller fragments or sediments by the forces of running water, moving ice and waves. The sediment are carried along by the rivers and are deposited at the bottom of lakes, oceans and seas. these are compressed and cemented due to extreme force and form a sedimentary rocks.When subjected to extreme heat and pressure,the igneous and sedimentary rocks undergo a change in their characteristics and form . This results into the formation of metamorphic rocks. This cycle of change from one rock to another is known as rock cycle.

The diagram explaining the rock cycle is as follows:
