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 best answer is C. Deep ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity(haline). This process is called thermohaline circulation. In the earth's polar region, ocean water gets very cold forming sea ice.
