Question

Q. “Ocean basins consist of a large number of varied physiography and variable distribution of temperature and pressure.” Consider the following statements in this regard:

Which of the above statements is/are correct?

• A. 1 only
• B. 2 and 3 only
• C. 3 only
• D. 1, 2 and 3

Answer 1

The correct option is A 1 only

Explanation:

• Statement 1 is correct: Sea Mount is a mountain with pointed summits, rising from the seafloor that does not reach the surface of the ocean. The Emperor seamount, an extension of the Hawaiian Islands in the Pacific Ocean, is a good example. Guyot is a flat-topped seamount. They show evidence of gradual subsidence through stages to become flat-topped submerged mountains
• Statement 2 is incorrect: With latitude, there is variability in the distribution of temperature in oceans. The temperature of surface water of oceans decreases from the equator towards the poles because the amount of insolation decreases poleward.
• Statement 3 is incorrect: The enclosed seas in the low latitudes record relatively higher temperatures than the open seas; whereas the enclosed seas in the high latitudes have lower temperatures than the open seas.
