Question

Write in brief about ocean circulation .

Answer 1

The deeper currents are produced by the sinking of colder water and the upwelling of warmer water. The global ocean circulation system transfers heat from low to higher latitudes, making the oceans responsible for about 40% of the global heat transport.Currents that flow deep in the oceans below the level affected by winds are generated by convection caused by variations in water density. Higher-density waters sink and displace (push aside or up) less –dense water. ... Winds also create ocean currents that can transport large volume of water across the oceans.
