Consider the following factors
Rotation of the Earth
Air pressure and wind
Density of ocean water
Revolution of the Earth
Which of the above factors influence the ocean currents?
Correct Answer:
(B)
1, 2 and 3
Ocean current is a continuous, directed movement of sea-water generated by forces such as rotation of the earth, wind, temperature and salinity difference, air pressure, sea water density difference etc. Revolution of the earth does not influence the ocean currents. Hence, option (b) is the correct answer.
Ques:
59
Consider the following statements:
Ocean currents are the slow-surface movement of water in the ocean.
Ocean currents assist in maintaining the Earth's heat balance
Ocean currents are set in motion primarily by prevailing winds
Ocean currents are affected by the configuration of the ocean.
Which of these statements are correct?
Correct Answer:
(D)
1, 2, 3 and 4
The flow of ocean water in a particular direction is called the oceanic current. Mostly ocean currents are set in motion by the prevailing wind. If the wind is slow, normally the surface water is in motion. Thus, statement 1 and 3 are correct. In cold regions hot streams (Gulf stream) and in hot regions cold streams play their role in heat stabilization. Thus statement 2 is also correct. Ocean currents are also affected by the configuration of the ocean besides prevailing winds and Earth's rotation. Thus, statement 4 is also correct.
Ques:

Which one of the following factors is responsible for the change in the regular direction of the ocean currents in the Indian Ocean?
Correct Answer:
(B)
Indian Ocean has Monsoon drift
The ocean currents of the Indian Ocean are slightly different from the Pacific and the Atlantic Ocean. Land and monsoon winds have a major impact on the Indian Oceanic current. The direction of current flow changes twice in the Northern Indian Ocean due to the North-East and South-West monsoon winds whereas Southern Indian Ocean currents have a definite pattern. Hence, option (b) is the correct answer.
