ANitrous oxide
BNitrogen gas
CArgon gas
DHydrogen gas
Answer & Solution
Correct answer: A. Nitrous oxide
1. A greenhouse gas absorbs and re-emits thermal radiation, trapping heat near the surface.
2. The gases that do this on Earth are carbon dioxide, methane, water vapor, nitrous oxide and ozone.
3. Nitrous oxide is on that list, so it is a greenhouse gas.
4. Nitrogen gas makes up most of the atmosphere but is not one of the greenhouse gases named.
