Answer 1

All of the statements are correct. Chemical weathering involves the formation of new substances through reactions with water or other substances, resulting in the breakdown of rock. Physical weathering, on the other hand, does not involve any chemical reactions and does not result in the formation of new substances. Physical weathering includes processes such as erosion, abrasion, and freeze-thaw cycles. Chemical weathering can also involve the input of plants and animals, but physical weathering does not necessarily involve them.
