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.
Because these huge circular currents are blocked by continents, smaller (though still giant) ocean current circles called gyres are formed. Differences in water density affect vertical ocean currents (movement of surface ocean water to the bottom of the ocean and movement of deep ocean water to the surface). Variations in water density are caused by variations in salinity (the amount of salt in water) and temperature.
