Dense water sinks to the bottom of the ocean and forms deep currents. Ocean currents are caused by the rotation of the earth, which creates the Coriolis Force (the water moves to the right in the northern hemisphere and to the left in It shares minerals & pollution attached to it becomes profoundly adulterated & later negligible. surface create surface currents in the ocean. The topography and shape of ocean basins and nearby landmasses also influence ocean currents. Satellite images of sea surface temperature can show the path of the warm Gulf Stream current with great precision. How do I choose between my boyfriend and my best friend? Deep ocean currents (also known as Thermohaline Circulation) are caused by: The sinking and transport of large masses of Dense-cold-salty water sinks to the ocean bottom. Density currents created by differences in water temperature and salinity. Compare and contrast western boundary currents to eastern boundary currents. The molecules slow down and move closer together, increasing the water's density. 8 How are ocean currents related to global circulation? The ocean currents may be warm or cold.
