Which effect results when wind interacts with Earth's rotation near a deep ocean surface current?

💡 Explanation

When wind acts on a surface current, the Coriolis effect deflects water movement, with each layer pushed by the above one also deflected slightly, because the rotation alters momentum transfer with depth. Therefore an Ekman spiral forms, rather than intensified upwelling, circulation, or oscillation, which require different regional or global mechanisms.
