← GeographyNear a rocky headland, which outcome reduces beach area after prolonged storms?
A)Increased sediment deposition seaward expands bars.
B)Wave refraction focuses erosive energy.✓
C)Rip currents redistribute offshore sediment input.
D)Aeolian processes stabilize dune sediment sources.
💡 Explanation
Wave refraction around the headland concentrates wave power because wave energy converges, thus intensifying erosion via hydraulic action. Therefore, focusing erosive energy reduces beach area, rather than deposition expanding bars or modification from aeolian processes.
