Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents are cohesive streams of seawater that circulate through the ocean.
The remaining 90 percent of the ocean moves with deep water currents. Deep water is different from surface water in two distinct ways. Deep water is much colder than surface waters, and deep water has a higher salt content. When salty water from a warm region is transported to a region that is cold, it tends to sink.
