Answer

Brief Explanations:

Chemical weathering involves chemical reactions that alter the composition of rocks or minerals. Acid rain contains acidic compounds that react with the materials in sidewalks (typically concrete, which has calcium carbonate), causing a chemical change. The other options (waves, ice, wind) are examples of physical weathering, which breaks down materials without changing their chemical composition.

Answer:

B. acid rain falling on sidewalks
