← GeographyWhich outcome can cause decreased upwelling when surface winds decline along a coastline?
A)Nutrient redistribution slows considerably✓
B)Halocline intensity immediately lessens overall
C)Thermohaline circulation fully intensifies locally
D)Coastal erosion drastically slows downshore
💡 Explanation
Nutrient redistribution slows greatly during weak winds because Ekman transport, a mechanism where surface winds drive water movement, is reduced; therefore, upwelling decreases, depleting nutrient supply, rather than intensifying circulation alone.
