SURFACE WATER
Ocean currents move warm water away from the equator toward the poles while cold water is in turn moved towards the equator . This is the main way in which the earth distributes surface heat and is a major climatic control. Approximately 4000 millions years ago , the earth was dominated by oceans and there was no land to interrupt the flow of the currents which would have flowed as straight lines, simply influenced by the earth rotation .
