Answer:
A differences in the density of ocean water
Explanation:. Salt water is denser than pure water. The density of water also depends on its temperature. Cooler water is denser than warmer water. Thus, both temperature and salinity affect the density of seawater.Cooler and saltier liquid water will sink, and warmer, less saline water will move in to replace it. As this process continues, it forms a worldwide “conveyor belt” of seawater. The cold, deep ocean current from the Arctic Ocean flows toward the North Atlantic Ocean and the warm surface currents flow from the North Atlantic Ocean toward the Arctic Ocean.
