← GeographyWhich outcome occurs when wave refraction concentrates energy on coastal stacks?
A)Increased wave-cut platform erosion✓
B)Stabilization of sediment deposition
C)Decreased longshore current velocity
D)Reduced tidal range amplification
💡 Explanation
Increased wave-cut platform erosion emerges because wave refraction focuses energy, increasing the hydraulic action and abrasion at the base through wave pounding, therefore accelerating stack base erosion rather than promoting sediment deposition because of energy dissipation.
