Final answer:
Chemical weathering involves chemical reactions that break down rocks, while physical weathering involves the physical disintegration of rocks.
Step-by-step explanation:
Chemical weathering and physical weathering are two different processes that contribute to the breakdown and alteration of rocks and minerals. Chemical weathering occurs when rocks are broken down or altered through chemical reactions. This can include processes like oxidation, hydrolysis, and dissolution. On the other hand, physical weathering involves the physical disintegration of rocks without any chemical changes. This can occur through processes like freeze-thaw cycles, abrasion, and exfoliation.
