Q2. 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

Answer:

Answer a: The statement is correct.

Answer b: The statement is wrong. The difference in temperatures of various parts of the ocean is the major reason behind the deep-sea currents. Warm water has a lower salinity and density. Such water comes to the surface of the sea. Coldwater with high density goes down. This movement causes deep sea water currents.

Answer c: The statement is wrong. Surface ocean currents form in both Polar regions as well as equatorial regions.

Answer d: The statement is true.

Answer e: The statement is wrong. The movement of icebergs is potentially dangerous, as it may hinder or hit the water vehicles.

Answer f: The statement is correct.
