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.

• Which effect is directly intensified when El Niño-Southern Oscillation (ENSO) causes a temporary reversal of the Walker circulation?
• Which outcome arises when increased sediment deposition at an alluvial fan's distributary channels exceeds the channel's incision rate?
• Which risk increases downwind when deforestation alters a regional albedo?
• Which outcome arises because deflation lowers sediment supply?
• Which weathering process predominates in the formation of a cirque's steep headwall?
• Which risk increases when concentrated livestock farming accelerates soil acidification above subsurface limestone?
