Question

what are the reasons responsible for the formation of deep ocean currents​

Answer 1

Answer:

Deep ocean currents are caused by differences in water temperature and salinity (density).

Answer 2

Temperature and Deep Ocean Currents - Ocean Surface ... Ocean currents arise in several ways. For example, wind pushes the water along the surface to form wind-driven currents. ... In these areas, the balance between gravity and Earth's spin causes geostrophic currents to flow. Deep ocean currents are caused by differences in water temperature and salinity (density).
