उत्तर

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.
