← GeographyWhich consequence results when prevailing winds weaken within significant oceanic gyres?
A)Reduced upwelling of nutrient-rich water✓
B)Increased stratification and algal blooms
C)Intensified deep-water current formation
D)Accelerated thermohaline circulation speed
💡 Explanation
When prevailing winds weaken, Ekman transport decreases because wind shear forces less surface water offshore, reducing coastal upwelling which brings nutrients to the surface. Therefore reduced upwelling results, instead of stratification, deep-water formation, or acceleration, each requiring increased wind force or density gradients.
