← GeographyWhich outcome results when wave-driven dissolution erodes coastal chalk cliffs?
A)Formation of prominent sea stacks✓
B)Increased rate of glacial isostasy
C)Decreased frequency of turbidity currents
D)Stabilization of existing sand dunes
💡 Explanation
Sea stacks form because differential erosion by wave action preferentially dissolves weaker rock, therefore isolating resistant rock masses rather than stabilizing dunes. Dissolution dominates limestone erosion, therefore glacial isostasy and turbidity currents will be less directly affected.
