Consider the following statements

,

Consider the following statements:

Statement I:
In January, in the Northern Hemisphere, the isotherms bend equatorward while crossing the landmasses, and poleward while crossing the oceans.

Statement II:
In January, the air over the oceans is warmer than that over the landmasses in the Northern Hemisphere.

Which one of the following is correct in respect of the above statements?

(a)

Both Statement I and Statement II are correct and Statement II explains Statement I

(b)

Both Statement I and Statement II are correct but Statement II does not explain Statement I

(c)

Statement I is correct but Statement II is not correct

(d)

Statement I is not correct but Statement II is correct

Explanation

• Statement I: In January, in the Northern Hemisphere, isotherms (lines of equal temperature) bend equatorward over land (colder) and poleward over oceans (warmer) due to temperature differences. This is correct. • Statement II: Oceans retain heat better than land, so in winter (January), air over oceans is warmer than over landmasses. This is correct. • Explanation Check: The warmer ocean air causes isotherms to bend poleward over oceans, and colder land air causes them to bend equatorward, so Statement II explains Statement I. Thus, (a) is the answer.
