Question

Which of the following gases cause the harmful greenhouse effect?

• A. Hydrogen
• B. Oxygen
• C. Carbon dioxide
• D. Nitrogen

Answer 1

Answer: (C)

Gases which cause greenhouse effect by trapping heat from solar radiation are:

1. Water vapour $\left(H_{2}O\right)$
2. Carbon dioxide $\left(C{O}_2\right)$
3. Methane $\left(C{H}_4\right)$
4. Nitrous oxide $\left(N_{2}O\right)$
5. Chlorofluorocarbons $\left(CFCs\right)$

Hydrogen, oxygen and nitrogen gases do not cause greenhouse effect.
