What is the cause of ocean currents

What causes ocean currents?
Oceancurrents 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.

What is the cause of ocean currents
What things causeoceancurrents? Oceancurrents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement- a process known as con…vection. Convection occurs because the oceanic waters heat up becoming less dense.

What Are the Causes of Ocean Currents? - Education
Ocean waters circulate constantly due to a number of dynamic forces, from the Earth's rotation to the salt content of water. WindThe friction of wind on the surface of the water causes water to move. When wind blows persistently, it causes the current to flow more quickly.

What are the causes of deep ocean currents? - Quora
Deep oceancurrentscaused mainly due to: 1. Salinity difference- higher the salinity water descend down and surrounding water rushes to fill this void caused. 2. Temperature difference- higher the temperature water expands and density reduces due to this water moves from below toward surface.
