The zone of rapid change from warm water to cold water with increasing depth in the ocean. What causes the flow of water in the ocean? What causes the two major types of ocean currents? Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Example, Warm currents of Koroshio makes the southern Japan less cold in winter whereas the cold current of Koroshio makes the winter longer and severe in north Japan. Earths rotation results in the Coriolis effect which also influences ocean currents. cin >> Horizontal movements are called currents, which range in magnitude from a few centimetres per second to as much as 4 metres (about 13 feet) per second.

List the three factors that control surface currents: Global winds, continental deflection and temperature, and the Coriolis effect. The warm Gulf Stream originating in the tropical Caribbean, for instance, carries about 150 times more water than the Amazon River. As the Earth's surface is heated unevenly by the sun, ocean water at the equator moves to the surface from the Equator and flows toward Earth's poles, where the water cools, becomes denser, sinks and flows back toward the equator creating a convection current. The ocean has an interconnected current, or circulation, system powered by wind, tides, the Earths rotation (Coriolis effect), the sun (solar energy), and water density differences. Surface currents are created by three things: global wind patterns, the rotation of the Earth, and the shape of the ocean basins. , Gravity. << "Enter today's temperature: "; The Gulf Stream is caused by a large system of circular currents and powerful winds, called an oceanic gyre.
