Question

what are the reasons reaponsible for the formation of deep ocean currents?.answer in one sentence​

Answer 1

Answer:

1)The density of sea water varies globally due to differences in temperature and salinity. Surface water is heated by the sun, and warm water is less dense than cold water.  

2)The earth's rotation also influences deep ocean currents.

Explanation:

Answer 2

Explanation:

They are driven by density and temperature gradients. The difference in temperatures of various parts of the ocean results into formation of the deeea currents. Warm water that has lower density comes to the surface of the sea while the Coldwater with high density goes down
