You are correct! When two words appear together as a term, the first word often acts as an adjective, describing the second word.

In the context of the rock cycle, the term "rock cycle" describes a process – the continuous transformation of rocks from one type to another.

Here's how it works:

* Rock: The noun being described. It refers to the solid, naturally occurring material that makes up Earth's crust.

* Cycle: The adjective describing the rock. It indicates that the rock goes through a continuous series of changes.

Therefore, "rock cycle" describes the process by which rocks are constantly being formed, broken down, and transformed over geological time.
