Which risk increases when longshore currents weaken along coasts?

💡 Explanation

Nutrient depletion near the surface increases if longshore currents weaken because upwelling, responsible for bringing nutrient-rich deep water to the surface, is diminished. Therefore, phytoplankton growth slows, therefore nutrient depletion rather than increased plankton or stable oxygen levels occurs in shallower water.
