• Both A and R are correct and R is the correct explanation of A.

• Both A and R are correct but R is not the correct explanation of A.

Answer 1

Both A and R are correct but R is not the correct explanation of A.

Explanation:

• A is correct: 
  Freeze-thaw weathering can occur in desert areas, especially in regions with occasional freezing temperatures. Deserts are not entirely devoid of water; it can seep into cracks in rocks.
• R is correct: 
  Water freezing in cracks expands, exerting pressure on the rock and causing it to break. This is the mechanism of freeze-thaw weathering. However, it’s important to note that this process doesn’t specifically define desert environments.
