← GeographyWhich consequence results when deep ocean currents slow?
A)Reduced nutrient upwelling to surface✓
B)Increased coastal erosion from waves
C)Decreased global average precipitation
D)Weakened thermocline layer formation
💡 Explanation
Slower deep ocean currents reduce the rate of nutrient upwelling because thermohaline circulation brings nutrient-rich water upwards. Therefore, nutrient availability decreases at the surface, rather than increased erosion due to wave action or decreased overall precipitation.
