Explanation:

Physical weathering breaks rock into smaller pieces without changing its chemical composition.

• Limestone reacting with acidic water is chemical weathering (changes rock chemistry).
• Water freezing/expanding in rock cracks breaks rock physically.
• Streams smoothing rock is physical abrasion, no chemical change.

Answer:

B. Rocks split when water seeps into cracks, freezes, and then expands.
C. Streams can smooth and sculpt rock over time.
