OCEAN CURRENTS.

OCEAN CURRENTS. 

the general movement of large mass of surface water in definite pattern is called ocean currents.

CAUSES OF THE MOVEMENT OF OCEAN CURRENTS. 

 The earth's rotation which results in the genesis of deflective or coriolis force.

The planetary winds.

Difference in the temperature of ocean waters between the equator and the poles.

Salinity of ocean affects the density of water, which is the main cause of movement of ocean water.

Shape and configuration of the continent determines the direction of ocean current.

OCEAN CURRENTS. 

Types of ocean currents on the basis of temperature can be divided into following. surface temperature are called warm currents.

cold currents: those ocean currents which flow from the polar region to the equatorial region, having a low surface temperature are called cold currents.
