Prelims 2024 · Geography · Question 54
Which of the following is/are correct inference/inferences from isothermal maps in the month of January? 1. The isotherms deviate to the north over the ocean and to the south over the continent. 2. The presence of cold ocean currents, Gulf Stream and North Atlantic Drift make the North Atlantic Ocean colder and the isotherms bend towards the north. Select the answer using the code given below:
Answer
1 only
1. Correct. In January, landmasses in the Northern Hemisphere cool faster than oceans, so isotherms bend equatorward (south) over continents and poleward (north) over oceans.
2. Incorrect. Gulf Stream and North Atlantic Drift are warm currents, not cold currents. They warm the North Atlantic and help isotherms bend northward; the statement is wrong because it calls them cold currents and says they make the ocean colder.
Therefore, only statement 1 is correct.
