What is ocean current? It is a movement of ocean that can bring the fish to other places . There are two kinds of circulation create the currents in the ocean. They are (1) breaking wind-driven circulation and (2) Thermohaline circulation. Wind-driven circulation result from the wind sets the surface waters into drive as currents. The currents generally pass horizontally-that is parallel to the earth¡¦s surface. The wind mainly affects just now the upper 100 to two hundred meters of water. However, the fall of wind-driven currents may extend to depths of 1,000 meters or more. Thermohaline circulation produces great erect currents hat flow from the surface to the ocean bottom and back. The currents generally result from differences in water temperature and salinity. The currents move sluggishly from the polar regions, along the sea floor, and back to the surface. In the polar regions, The surface waters puzzle colder... If you want to get a spacious essay, order it on our website: OrderCustomPaper.com
