Mariyah Poole · Answer 1

Chemical weathering changes the composition of a rock, while physical weathering does not.

Explanation:

Chemical weathering of rocks is a chemical reaction. A chemical change is known to change the composition of a substance. Once a substance is subjected to a chemical reaction, a new substance is automatically formed thereby changing the composition of the original substance.

A physical weathering agent does not affect the composition of rocks. This a major difference between chemical and physical weathering processes. For instance, physical weathering caused by ice has nothing to do with internal rock composition.
