← GeographyWhich outcome promotes stack collapse during storm surges?
A)Increased hydraulic action stresses the stack✓
B)Decreased wave base near sediment structures
C)Sediment deposition reducing refraction forces
D)Reduced longshore drift sediment replenishment
💡 Explanation
Storm surges elevate water levels, and increased hydrostatic pressure within fractures weakens stacks via hydraulic action; therefore, structural failure is expedited, rather than mitigated by sediment-related changes.
