Answer
# Brief Explanations:
Chemical weathering involves chemical reactions that change the composition of rocks. Acid rain contains acidic substances that react chemically with rocks, causing weathering. Waves washing over rocks is mechanical weathering (abrasion). Ice forming in cracks is physical (mechanical) weathering due to expansion - contraction. Wind blowing against rocks is also mechanical weathering (abrasion and erosion).
# Answer:
B. acid rain falling on rocks
