← GeographyWhich coastline outcome accelerates when a stack's aspect ratio drops below 1:3?
A)Increased wave refraction severity
B)Accelerated hydraulic action erosion✓
C)Reduced longshore transport blockage
D)Enhanced tombolo formation probability
💡 Explanation
Hydraulic action damage increases. A shorter, stockier seastack experiences greater force from breaking storm waves because reduced height diminishes wave refraction, therefore accelerating the stack's erosion rather than offering any increased shading protection against undercutting.
