Which effect determines the direction ocean currents are deflected relative to wind direction?

A)Coriolis effect
B)Ekman spiral
C)Buoyancy effect
D)Thermocline effect

💡 Explanation

When wind initiates ocean currents, the Coriolis effect deflects them because the spherical Earth rotates, influencing objects' paths. Therefore the current is deflected due to the Coriolis effect, rather than Ekman spiral (accounts for depth variation), buoyancy (density), or thermocline (temperature gradient) influences related mechanisms.
