Ocean Circulation     The ocean is constantly in motion, distributing water and heat to all corners of the globe. In effect, the ocean acts as a circulating machine that makes Earth’s climate equitable. Ocean currents follow well-defined courses.  Why? Difference in heating leads to the different in surface temperature. This difference causes the movement of water boy (Ocean) that form the current. This method of heat transfer is called as Convection; hence it is sometimes mentioned as convectional currents.  Just like that happens our kitchen while boiling water.     How important it is?   The ocean transports tremendous quantities of seawater, serving as a global conveyor belt over the planet. Abyssal storms stir the deep-ocean floor, shifting sediments on the seabed. El Niño currents generate unusual weather patterns throughout the world. Waves and tides are constantly changing and rearranging the shoreline.       ...
