What are the two main types of weathering?

Question

Abrasion and Sediment Weathering

Mechanical (physical) and Chemical Weathering

Wind and Water Weathering

Rock Cycle Weathering

Answer 1

The two main types of weathering are Mechanical (physical) Weathering and Chemical Weathering.

• Mechanical weathering involves the physical breakdown of rocks into smaller pieces without altering their chemical composition. This can occur through processes such as freeze-thaw cycles, thermal expansion, and abrasion.

• Chemical weathering, on the other hand, involves the alteration of the minerals within rocks, often through reactions with water, acids, or gases, leading to changes in the rock's composition.

So the correct answer is: Mechanical (physical) and Chemical Weathering.
