Which gas contributes most to the natural greenhouse effect?
Show Hint
Major greenhouse gases:
\[
\boxed{
\text{H}_2\text{O}
\gt
\text{CO}_2
\gt
\text{CH}_4
\gt
\text{N}_2\text{O}
}
\]
Water vapour contributes the most to the natural greenhouse effect.
Updated On: Jul 23, 2026
- Carbon dioxide
- Methane
- Water vapour
- Nitrous oxide
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Water vapour is the most abundant greenhouse gas in the atmosphere and contributes the largest share to the Earth's natural greenhouse effect.
Although gases like carbon dioxide and methane are important, water vapour has the greatest overall contribution.
Hence,
\[
\boxed{\text{Water vapour}}
\]
is the correct answer.
Therefore,
\[
\boxed{(C)}
\]
