Which phenomenon primarily deflects fast-moving ocean currents within large oceanic gyres?

💡 Explanation

When an ocean current moves, the Coriolis force deflects it because Earth rotates, causing moving objects in the Northern Hemisphere to veer right and those in the Southern Hemisphere to veer left. Therefore Coriolis force deflects currents, rather than Ekman transport, thermohaline circulation, or tidal forces, which have different primary effects.
