Which mechanism causes coastal upwelling along western continental streams under specific wind conditions?

💡 Explanation

When wind blows along a western continental stream parallel to the coast, Ekman transport occurs because the Coriolis effect deflects the surface water offshore, causing deeper, nutrient-rich water to rise. Therefore, Ekman transport causes coastal upwelling rather than geostrophic flow, thermohaline circulation, or tidal forces, which have different primary mechanisms.

• Which mechanism causes increased coastal erosion near large river estuaries when upstream dams alter streamflow patterns?
• Which outcome occurs when trade winds weaken along the equator in the eastern Pacific Ocean, reducing upwelling?
• Which outcome primarily results when tectonic subsidence forms a deep lake basin in a humid region?
• Which effect occurs when sustained offshore winds drive coastal upwelling of nutrient-rich water?
