← GeographyWhich weathering process causes exfoliation domes in granitic landforms?
A)Differential thermal expansion and contraction✓
B)Frost wedging and cryoturbation cycles
C)Dissolution via precipitation and runoff
D)Hydrolysis along fault lines.
💡 Explanation
Exfoliation domes occur because of the mechanism of unloading; erosion reduces the overlying pressure, therefore the granite expands, causing curved fractures, rather than fracturing due to ice or chemicals under other conditions.
