Question

Which of the following is not a Green House Gas?

• A. Nitrogen
• B. Methane
• C. Nitrous oxide
• D. Carbon dioxide

Hint:

Nitrogen is an inert gas that does not contribute to the greenhouse effect, unlike methane, nitrous oxide, and carbon dioxide.

Answer 1

The Correct Option is A

Step 1: Understanding Greenhouse gases.
Greenhouse gases are those that trap heat in the Earth's atmosphere and contribute to the greenhouse effect, which leads to global warming. Common greenhouse gases include methane, nitrous oxide, and carbon dioxide.
Step 2: Identifying the non-Greenhouse gas.
- (A) Nitrogen: Nitrogen is the most abundant gas in the Earth's atmosphere but does not contribute significantly to the greenhouse effect.
- (B) Methane: Methane is a potent greenhouse gas, much stronger than carbon dioxide in trapping heat.
- (C) Nitrous oxide: Nitrous oxide is a greenhouse gas that contributes to global warming.
- (D) Carbon dioxide: Carbon dioxide is a well-known greenhouse gas responsible for trapping heat in the Earth's atmosphere.

Step 3: Conclusion.
Thus, the correct answer is (A) Nitrogen, as it is not a greenhouse gas.
Final Answer: (A) Nitrogen.
