Chemical weathering is different than mechanical weathering because what?

Wedging, exfoliation and abrasion are all caused by the process of physical weathering.

Explanation:

Chemical weathering is weathering by erosional agents such as water, wind, mostly chemicals that interact wot water to form acids that react with the elements of the rocks. Physical changes in the structure of the rocks such as structural deformations, and is called mechanical weathering as its wear and tear of joints in rocks. Leading to the development of cracks and fractures in rocks, both the physical weathering leads to the breakdown of rocks and the formation of soil.
