Question

which of the following is responsible for deep ocean circulation? coriolis force density differences friction wind

Explanation:

Deep - ocean circulation is mainly driven by density differences. Density differences in seawater are caused by variations in temperature (thermo) and salinity (haline), which is known as thermohaline circulation. The Coriolis force affects the direction of surface - water movement (like in surface currents) but is not the main driver of deep - ocean circulation. Friction has a more limited role in driving large - scale ocean circulation patterns. Wind is a major force for surface - water circulation (such as in the formation of wind - driven surface currents), not for deep - ocean circulation.

Answer:

density differences
