What is the difference between mechanical and chemical weathering?

Question

A.There is no difference between the two types of weathering.

B.Mechanical weathering occurs when when rocks are broken down into smaller rocks, and chemical weathering occurs when rocks are broken down by acids, oxygen, or carbon dioxide

C.Mechanical weathering occurs when rocks are broken down by acids, and chemical weathering occurs when rocks are broken down into smaller rocks

Answer 1

The correct answer is:

B. Mechanical weathering occurs when rocks are broken down into smaller rocks, and chemical weathering occurs when rocks are broken down by acids, oxygen, or carbon dioxide.

Mechanical weathering involves the physical breaking down of rocks into smaller pieces without changing their chemical composition, while chemical weathering involves chemical reactions that change the mineral composition of the rocks, often due to interactions with water, acids, and gases.
