What are ocean currents?
Advertisements
उत्तर
Ocean currents are streams of water flowing constantly on the ocean surface in definite directions. Ocean currents are formed because of the temperature differences between the ocean water present at different latitudes. The further one travels from the Equator, the colder the ocean water generally becomes. Due to convection, the warm currents that originate near the Equator move towards the Poles. The cold currents carry ocean water from the Polar or higher latitudes to the tropical or lower latitudes.
