← GeographyWhich mechanism accelerates coastal erosion when surface water is drawn offshore by strong winds?
A)Wave exposure from reduced seabed friction✓
B)Sediment starvation due to upwelling suppression
C)Ice formation from thermohaline circulation changes
D)Ocean acidification from phytoplankton bloom
💡 Explanation
When strong offshore winds draw surface water away from the coast, wave exposure is heightened because the removal of shallow water reduces seabed friction, increasing wave energy along the coastline. Therefore wave exposure and erosion result, rather than sediment starvation, ice formation, or acidification which involve different oceanographic processes.
