The atmosphere is mainly heated by:

Explanation

After being heated by Solar rediation, the Earth transfers heat in long-wave form to the nearby layers of the atmosphere. Long-wave radiation is absorbed by atmospheric gases (especially carbon dioxide and other greenhouse gases). Hence, the Earth’s atmosphere is mainly heated by long-wave terrestrial radiation. 26.. Which of the following is a greenhouse gas? (a) Carbon dioxide (c) CFC (b) Ozone (d) Methane (e) None of the above / More than one of the above B.P.S.C. CDPO 2022 Ans. (e) Due to the presence of greenhouse gases, the atmosphere behaves like a greenhouse. The atmosphere allows incoming solar radiation to pass through, but it absorbs most of the long-wave radiation emitted upward from the Earth’s surface. Gases that absorb long-wave radiation are called greenhouse gases. Some major greenhouse gases include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons (CFCs), and ozone. Therefore, since more than one option is correct in this question, the correct answer is option (e). 27.. Which gas contributes to global warming through its greenhouse effect? (a) Carbon dioxide (b) Nitrous oxide (c) Methane (d) More than one of the above (e) None of the above 68th B.P.S.C. (Pre) 2022 Ans. (d) See the explaination above the question
