OCEANIC WATER CIRCULATION

OCEANIC WATER CIRCULATION

In general , ocean currents parallel the movement of wind across the earth surface . Incoming solar energy is greatest at the equator and least at the poles . So water in the oceans heat up most at the equator and flow polewards ,cooling as moves north or south towards the arctic or antarctic . The flow is eventually reverse and cold water currents move back towards the equator . These oceans currents are as a vast system for moving heat from the equator towards the poles and a major influence on the distribution of the earth climate .
