How can moving water contribute to physical weathering?

Question

A. It can cause rocks to bump against each other. B. It can cause the formation of new minerals in rocks. C. It can transport rocks to different locations. D. It can make rocks expand and contract.

Answer 1

The correct answer is A. It can cause rocks to bump against each other.

Moving water can lead to physical weathering by eroding the rocks and causing them to collide and grind against one another, thereby breaking them down into smaller pieces. This process is known as abrasion, which is a key mechanism of physical weathering.
