Question

Examine the given statements and correct the wrong ones.
(a) Ocean currents give specific direction and velocity to the water
(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

"a) Ocean currents happens due to factors like air, salinity, temperature, etc., which changes the speed and direction of the water.

b) Deep ocean currents flow with comparatively less velocity than surface currents, since, its speed is affected by density and temperature gradients.

c) Surface ocean currents form in both Polar regions as well as equatorial regions.

d) Ocean currents accounts for 97% of earth's water that flow nearly to 2/3 portions of the earth and creates more oxygen.

e) The movement is icebergs are potentially dangerous, as it may hinder or hit the water vehicles.

f) True."

Answer 2

Answer:

even though the velocity of ocean current is less the water carried by them is immense
