The ocean serves as the major source for evaporation of water back into atmospheric circulation. At the poles, they are also a source of fresh water as sea ice, but this does not contribute significantly to the production of water resources.
Igneous rock is transported by wind or moving water until they are deposited in other regions where they settle in layers.
It is gravity that drives thermohaline circulation. It's a gravity current. We usually apply the term thermohaline circulation to the deep ocean currents that are driven by gravity. Colder water or water that has a higher salt content than other water is more dense, and gravity will act on it to pull it "down" deeper. It will displace warmer or less salty water and move to greater depths. This sets the stage for a deep ocean current we call a thermohaline expressway. Use the links below for more information on gravity currents (which are sometimes called density currents)._______________________sflo:I would say this answer is limited in explaining what drives thermohaline circulation. Changes in density certainly affect circulation, particularly when water emerges from the deep or submerges to depths (upwelling and downwelling), but the effects of "gravity" on water masses of varying densities aren't a driver of circulation, per se. I would like to point that within the "thermohaline circulation," "thermo-" and "haline" are both components of the name. Thus in a more elemental manner, it makes more sense to explain this phenomenon by temperature and salinity differences, as well as the resulting changes in density, rather than merely "gravity."For a great snap-shot of our current understanding (or rather lack-therof) of the thermohaline circulation, what drives it, and how it affects or is affected by climate, please look-up:"Thermohaline circulation: The current climate" Nature421, 699 (13 February 2003) | doi:10.1038/421699a == ==
Carbon Dioxide dissolves in ocean water. Plants in the ocean use the carbon dioxide dissolved in the ocean water.
This section of the ocean from floor to surface is called the water column.
Current
Deep ocean circulation(90% of ocean water) is caused by differences in temperature, salinity and suspended load. It is referred to as "Thermohaline"- meaning heat and salt- circulation.
Thermohaline circulation brings oxygen rich water to the deep ocean.
Deep water ocean current
Heat
Thermohaline circulation is the process of cold water at the poles creeping along the ocean floor. It meets with north and south polar water creates a dawdling subsurface circulation.
Salts are dissolved from the earth and transported by rivers in oceans.
Salt is dissolved from the earth and transported by rivers in seas/oceans.
