The global ocean circulation system transports heat worldwide and affects climate in many areas. For example, Europe would have much colder winters if it were not for the Gulf Stream. Winds blow surface waters and cause ocean currents. But the waters below the depths of the wind's influence flow because of differences in temperature and saltiness (called salinity). On this page you can explore interactive about heating and circulation, then take a quiz to test your knowledge.
