← GeographyWhich outcome accelerates coastal erosion within ocean gyres?
A)Wind-driven Ekman transport convergence✓
B)Increased thermocline stratification stability
C)Reduced nutrient upwelling strength
D)Enhanced sediment deposition rate
💡 Explanation
Ekman transport causes surface water to converge in the gyre centers, increasing sea level and wave heights; because higher waves amplify erosion, convergence therefore accelerates coastal erosion driven by wave energy, rather than reduced upwelling which would lessen biological weathering.
