Consider the following statements:
Statement-I: The temperature in the southern hemisphere is considerably lower than that in the northern hemisphere.
Statement-II: The large mass of ice-covered Antarctic continent is an important factor of lower temperatures in the southern 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 is the correct explanation for Statement-I.
(b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I.

ONLiNE UPSC · Accepted Answer

Statement-I is correct: The Southern Hemisphere generally experiences lower average temperatures than the Northern Hemisphere. This is mainly due to the dominance of oceans, which absorb and retain heat more effectively, moderating temperature variations.
Statement-II is correct: Antarctica is the coldest place on Earth, with its ice-covered surface reflecting a large amount of solar radiation (high albedo), contributing to lower regional temperatures. This cooling effect does extend to the Southern Hemisphere, but it is not the sole reason for its overall lower temperature. The primary reason is the greater oceanic coverage in the Southern Hemisphere, which moderates temperature extremes.

While both statements are correct, Statement-II is not the primary or solefor Statement-I. Both Statement-I and Statement-II are correct, but Statement-II is not the correctfor Statement-I.
