Which of the following is not a greenhouse gas?
Show Hint
A greenhouse gas is a gas that produces heat in the atmosphere when its concentration increases.
- Carbon dioxide
- Water vapours
- Methane
- Oxygen
The Correct Option is D
Solution and Explanation
A greenhouse gas is a gas that produces heat in the atmosphere when its concentration increases. It gets stuck in the environment and can't escape the internal layer of the atmosphere of Earth. These gases cause pollution as they contaminate the environment.
Examples of greenhouse gases: Carbon dioxide, Chlorofluorocarbon, Methane, sulphur dioxide, etc.
Therefore, oxygen is not a greenhouse gas.
