Answer 2

Answer:

A.) It can cause rocks to bump against each other.

Explanation:

Let's look at a stream or river for example:

When water moves roughly, it takes along many rocks or pebles. As they move, they bump into each other, causing one rock to rub off the other. This can cause friction and eventually smooth out the rock.
