Step-by-step explanation:
Coriolis effect: It is an apparent deflection of the moving object. This is an apparent deflection of moving air or water caused by the rotation of the earth.
Currents are created by wind. Their directions are determined by coriolis effect. The earth is in constant motion. It describes the rotation of the earth which steers winds and the surface current. The direction of the wind blows from north and south towards equator.
Earth is sphere in shape. It spins on its axis in a counterclockwise direction when it is seen from north pole.
The object on the equator moves faster than the object further from the equator. The speed of currents and winds are faster at the equator than poles.
