Answer:

The answer to your question is below

Explanation:

Because similar to living things, some rocks are formed and it takes a long period to degrade them. During this period new rocks are born, some of these rocks can react with some compounds of the environment and can form new rocks or can be degraded.

What I try to say is that rock formation takes a lot of time and while some rocks disappear new rocks are created.
