ANitrogen, oxygen, argon and neon
BWater vapour, CO2, methane, ozone
CHydrogen, helium, methane and ozone
DOxygen, ozone, argon and methane
Answer & Solution
Correct answer: B. Water vapour, CO2, methane, ozone
1. Greenhouse gases absorb the infrared radiation the earth re-emits and send it back in all directions, trapping heat.
2. The major ones are water vapour, carbon dioxide, methane and ozone.
3. Nitrogen and oxygen dominate the air by volume but are not greenhouse gases, which is why the first option is tempting and wrong.
4. Less than half a percent of air molecules do this heat trapping work.
