Question

What is ocean current ? How it is caused ?

Answer 1

Surface currents are generated largely by wind. Their patterns are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.  Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.

Answer 2

Hey...!!!

The ocean current is the continuous movement of a mass of water in a particular direction. These are of 2 types :-

1) Cold Current

2) Warm Current

These are formed due to heating and cooling of the ocean water. Due to higher density of cold water, it sinks down below the warm water. Thus, the cold water of the polar region moves slowly towards the equator along the bottom of the ocean. The warm water near the equator moves along the surface of the ocean towards the poles.
In this manner, ocean currents are caused.

Hope it helps...!!,
