What is the main climate-related role of carbon dioxide in the atmosphere?
Answer and explanation
Correct answer: It traps heat and contributes to the greenhouse effect
Carbon dioxide is a greenhouse gas that absorbs part of the outgoing infrared radiation emitted by Earth’s surface. This process helps retain heat in the lower atmosphere and contributes to the natural greenhouse effect; increased concentration can intensify warming. Thus option A is correct. It is not the most abundant gas, does not block all sunlight, and does not simply make oxygen for respiration.
