Answer:
Wedging, exfoliation and abrasion are all caused by the process of physical weathering.
Step-by-step 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.
