← GeographyAlong what stream alignment does an ocean current form due to wind?
A)Ekman spiral induces surface flow✓
B)Geostrophic flow reduces Coriolis deflection
C)Thermohaline circulation causes upwelling
D)Salinity gradients affect stream turbidity
💡 Explanation
The Ekman spiral mechanism induces surface flow due to wind stress because surface water drags lower layers. Therefore, an initial wind direction becomes a spiral current rather than a simple drift, and Coriolis force deflects deeper flow.
