Answer 1

Moving water primarily contributes to physical weathering by causing rocks to bump against each other. This process, often referred to as abrasion, occurs when flowing water transports sediment and rocks, and as they collide with one another, they gradually wear down and break apart. Therefore, the correct answer is:

It can cause rocks to bump against each other.
