← GeographyWhich result occurs when trade wind reduction disrupts thermocline?
A)Upwelling nutrient supply is constrained.✓
B)Increased coastal erosion accelerates inland.
C)Surface air temperatures decrease quickly.
D)Polar ice sheet thickness slowly increases.
💡 Explanation
Reduced trade winds weaken coastal upwelling during El Niño; this weakens Ekman transport because surface waters are moving less offshore, therefore, the nutrient upwelling is constrained, rather than other large-scale effects like the air temperature or ice.
