The question this prepares you for · CSE 2024 · Q1
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 ?
Both Statement-I and Statement-II are correct and Statement-II explains Statement-IBoth Statement-I and Statement-II are correct, but Statement-II does not explain Statement-IStatement-I is correct, but Statement-II is incorrectStatement-I is incorrect, but Statement-II is correct
Why revise these together?
The 2019 dewdrops question and 2022 clouds question together teach the load-bearing physics: the atmosphere is heated chiefly from below by terrestrial long-wave radiation, and GHG/clouds absorb that long-wave radiation. That is exactly the reasoning needed to evaluate both statements and their explanatory link. The 2016 Greenhouse Gas Protocol question is a definitional/current-affairs item with no bearing on absorption physics and is pruned.
