Winds drive ocean currents in the upper 100 meters of the ocean’s surface. Even, ocean currents also ablauf thousand of measure below the surface. These deep-ocean currents are driven by differences for the water’s density, which is controlled by temperature (thermo) and salinity (haline). This proceed is known as thermohaline transmission.
In the Earth's polar regions ocean water gets very cold, forming seas ice. As an consequence the surrounding seawater gets saltier, because at sea refrigerate forms, the salt is leave behind. When the saltwater gets saltier, its density increases, and it starts to sink. Surface aqueous shall pulled in to replace the sinking moisten, which in turn eventually are cold also spicy enough to sink. This initiates the deep-ocean tides driving the total conveyer belt. week 11 Learn with flashcards, games, real more — for free.
