Which one among the following substances is NOT a 'green house' gas ?
Greenhouse Gas Basics
A greenhouse gas is a gas in the Earth's atmosphere that absorbs and emits thermal infrared radiation. This process causes the greenhouse effect, leading to warming of the planet's surface.
Analyzing Atmospheric Gases
Let's examine the options provided:
- Water vapour (H2O): A potent and abundant natural greenhouse gas.
- Chlorofluorocarbon (CFC): Synthetic compounds that are very effective greenhouse gases, although their use is now restricted.
- Methane (CH4): A significant greenhouse gas produced naturally and through human activities.
- Nitrogen (N2): Makes up about 78% of the Earth's atmosphere. However, diatomic molecules like N2 and O2 do not effectively absorb thermal infrared radiation and are therefore not considered greenhouse gases.
Identifying Non-Greenhouse Gas
Based on the analysis, Nitrogen does not contribute to the greenhouse effect in the same way as the other listed substances.
Therefore, Nitrogen is the correct answer.
Important Questions from Climate Change & Global Warming

B. CH$_4$
C. N$_2$O
D. CFCs
Choose the correct answer from the options given below:It is reported that there is an ongoing decrease in the pH value of ocean water because of global warming. It happens due to:
