The atmosphere is largely transparent to incoming shortwave solar radiation, which primarily reaches and heats the Earth&#8217;s surface. The heated surface then emits longwave terrestrial radiation. Greenhouse gases in the atmosphere, such as carbon dioxide, are effective absorbers of this longwave radiation. The absorption of terrestrial radiation by greenhouse gases is the primary mechanism by which the atmosphere is heated. Therefore, the atmosphere is heated more by terrestrial radiation than by incoming solar radiation directly.<br \/>\nStatement-II is correct. Carbon dioxide and other greenhouse gases (like water vapor, methane, nitrous oxide) are indeed good absorbers of longwave (infrared) radiation emitted by the Earth&#8217;s surface.
