Soil D As the name suggests, the wind-driven circulation is driven by the prevailing winds, primarily the easterlies in the tropics and the westerlies in the mid-latitudes. In fact, it is the densest ocean water on Earth! Since the center of the Earth gets more sunlight, it is. The top few meters of the ocean store as much heat as Earth's entire atmosphere. The oceans are mostly composed of less dense water near the surface over more dense water in the ocean depths.
