Despite its small amount, why is the thermal effect of carbon dioxide large?
Answer and explanation
Correct answer: Because it absorbs long-wave energy emitted by Earth
Carbon dioxide is radiatively active: it absorbs and re-emits portions of the long-wave infrared radiation emitted by Earth’s surface. This influences the escape of heat to space and contributes to the greenhouse effect, even though its concentration is much smaller than nitrogen or oxygen. Option A identifies the relevant mechanism. Density, moonlight and permanent rainfall stoppage do not explain its thermal effect.
