Question

Which factor is the predominant motive force responsible for the origin of an ocean current?

Answer 1

Factors responsible for its formation-

Gravity, wind, the Coriolis Effect, temperature, salinity and density differences.

Surface oceanic currents are sometimes wind driven and develop their typical clockwise spirals in the northern hemisphere and counter clockwise rotation in the southern hemisphere because of imposed wind stresses.

Deep ocean currents are driven by density and temperature gradients
