What causes deep currents?
the movement of the ocean and the wind
Deep ocean currents are in the depths of the oceans. Surface current are at the surface, not deep down. Deep ocean currents bring vitamins and nutrients to the shore, surface currents do not. Deep ocean currents are caused by salinity and temperature differences. Surface currents are cause by the force and impact of the wind.
The relationship between the density of ocean water and the formation of deep currents. Differences in the temperature and salinity and the resulting differences in density cause variations in the movement of deep currents. For example, the deepest current, the Antarctic Bottom Water, is denser than the North Atlantic Deep Water. Both currents spread out across the ocean floor as they flow toward each other. Because less dense water always flows on top of denser…
