Question

(b) The deep ocean currents flow with high velocity
(c) Generally, surface ocean currents are formed in the equatorial regions.
(d) Ocean currents hold great importance for human life.
(e) The movement of icebergs is not dangerous for water transport
(f) Water becomes warm near Brazil due to ocean currents. On the other hand, it becomes cold near African coast.​

Answer 1

Answer:

b) Deep ocean water constitutes about 90% of the ocean water. Unlike, surface ocean currents which are driven by high-speed planetary winds, deep ocean water is driven by differences in temperature and density. Thus, the velocity of deep ocean currents is low compared to surface currents.
