Here is the answer to your querry,
Anocean currentis a continuous, directed movement ofocean watergenerated by the forces acting upon thismean flow, such asbreaking waves,wind,Coriolis effect,cabbeling,temperatureandsalinitydifferences andtidescaused by the gravitational pull of theMoonand theSun.Depth contours,shorelineconfigurations and interaction with other currents influence a current's direction and strength. A deep current is any ocean current at a depth of greater than 100m.A part ofoceanographyis the science studying ocean currents.
Ocean currents can flow for great distances, and together they create the great flow of the global conveyor belt which plays a dominant part in determining theclimateof many of theEarths regions. Perhaps the most striking example is theGulf Stream, which makesnorthwest Europemuch moretemperatethan any other region at the samelatitude. Another example isLima, Peru, where the climate is cooler (sub-tropical) than the tropical latitudes in which the area is located, due to the effect of theHumboldt Current.
Hope it was informative.
