write the reasons for formation of ocean currents?
Answers 2
Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.

Answer:
Ocean currents refer to the steady movement or flow of surface ocean water in a prevailing direction. Various forces act upon ocean water, causing it to move. They include the wind, temperature, breaking waves and at tides, and sometimes underground forces like earthquakes.
Ocean currents are the movements of ocean water due to gravity, the rotating earth (Coriolis effect), water density, the sun, and wind. The various forces determine the size, speed direction, and shape of ocean currents. The water can either move horizontally – known as currents, or vertically – known as downwellings or upwellings.
