Final answer:
Moving water contributes to physical weathering through rock abrasion, transport, and expansion/contraction.
Step-by-step explanation:
Moving water can contribute to physical weathering in several ways. Firstly, it can cause rocks to bump against each other as they are carried downstream, leading to abrasion and the breaking down of rocks. Secondly, it can transport rocks to different locations, where they can experience further weathering processes. Finally, moving water can cause rocks to expand and contract due to the freezing and thawing cycles, which can eventually lead to the disintegration of rocks.
