Upwelling occurs when the wind blows towards the equator. It mostly happens along the western margin of continents. Wind blows and causes the water to blow towards the equator. The force of the wind makes the water turn west wards, away from the cost. In this case, the water up wells or rises from the depth of 60 to 200 meters and this risen water replace the water that has been moved away from the cost with the force of the wind. The water that has moved away from the coat runs south wards because the surface of the earth around the North Pole rotates at a greater speed while it moves towards the equator.
