Which consequence results when deep ocean currents slow?

💡 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.
