Consider the following statements: Statement I: The atmosphere is heated more by incoming solar radiation than by terrestrial radiation.
Statement II: Carbon dioxide and other greenhouse gases in the atmosphere are good absorbers of long-wave radiation.
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 incorrect
(d) Statement I is incorrect, but Statement II is correct
Correct Answer: (d) Statement I is incorrect, but Statement II is correct
Explanation:
Statement I is incorrect because the atmosphere is primarily heated by terrestrial radiation (long-wave radiation emitted by the Earth’s surface) rather than incoming solar radiation.
Statement II is correct as carbon dioxide and other greenhouse gases are good absorbers of long-wave radiation, contributing to the greenhouse effect.
