Q. Which of the following is not a Greenhouse gas?
Answer: D
Notes:
Explanation: Greenhouse Effect:
- The solar energy trapped by the earth atmosphere and radiate it slowly so to cover our earth with a warm blanket.
- This is the natural process of the greenhouse effect on earth to maintain its temperature and makes the earth perfect for life.
- Greenhouse gases are carbon dioxide, other greenhouse gases are methane, water vapour, nitrous oxide, CFCs and ozone.
- Values of radiation absorbed by the greenhouse gases are as follow:
| Gas | Value of absorption in percentage |
| Ozone | 10.2 % |
| Methane | 16.3 % |
| Carbon Dioxide | 56.4 % |
| Nitro Oxide | 5.4 % |
Global warming:
- If the amount of greenhouse gases crosses by delicate proportion, the natural greenhouse balance may get disturbed and there is a continuous rise in temperature of the earth by trapping the solar heat continuously.
- This creates the overall effect of Global warming.
