← GeographyWhich outcome happens when thermal gradients near ocean streams produce high pressure cells?
A)Enhanced coastal upwelling occurs✓
B)Localized sea fog dissipates
C)River discharge rates decrease
D)Glacial ice-melt accelerates
💡 Explanation
Enhanced coastal upwelling occurs because anticyclonic wind forcing causes Ekman transport, which draws deep, cold, nutrient-rich water to the surface. Therefore, upwelling increases rather than river discharge decreasing, because deep-water currents power the system.
