← GeographyWhich outcome is accelerated when increased wave energy weakens sedimentary rock?
A)Increased sea stack formation✓
B)Enhanced barrier island stability
C)Decreased sediment deposition
D)Reduced longshore drift volume
💡 Explanation
More wave energy causes accelerated hydraulic action, where wave impact compresses air in rock fissures, because the expansion fractures the rock, leading to detached isolated columns; therefore sea stacks increase, rather than increased stability or reduced sediment movement/deposition.
