Which phenomenon amplifies coastal upwelling along western continental margins?

💡 Explanation

When wind blows parallel to a western coast, the Coriolis effect causes the water to deflect to the right (in the Northern Hemisphere). Ekman transport then moves the surface water offshore, forcing the upwelling of deep, nutrient-rich water. Therefore, the Coriolis effect and Ekman transport amplifies upwelling, rather than insolation, precipitation, or convergence, which contribute to other oceanic processes.
