Answer
# Brief Explanations:
Chemical weathering involves chemical reactions that change the composition of rocks. Acid rain contains acidic substances like sulfuric and nitric acids which react with minerals in rocks and sidewalk - materials, causing chemical changes. Waves washing over rocks, ice forming in rock cracks, and wind blowing against rocks are examples of physical weathering which only changes the physical appearance of rocks without altering their chemical composition.
# Answer:
B. acid rain falling on sidewalks
