How does wind cause ocean currents?

Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms.

Explanation:

... Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.

The winds pull surface water with them, creating currents. As these currents flow westward, the Coriolis effect—a force that results from the rotation of the Earth—deflects them. ... In contrast to wind-driven surface currents, deep-ocean currents are caused by differences in water density.
