Solution
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.
