Greenhouse effect is the comulative result of the influences of certain gases. Identify the gas which is not involved in this influence:

Options

A. Methane
B. Carbon dioxide
C. Chloroflurocarbons
D. Nitrogen

Answer

**Step-by-Step Solution:**

1. **Understanding the Greenhouse Effect:**
- The greenhouse effect is a natural process that warms the Earth’s surface. It occurs when the Sun's energy reaches the Earth and is reflected back to space in the form of infrared radiation. Certain gases in the atmosphere trap this heat, preventing it from escaping.

2. **Identifying Greenhouse Gases:**
- Common greenhouse gases include:
- Methane (CH₄)
- Carbon Dioxide (CO₂)
- Chlorofluorocarbons (CFCs)
- These gases have the ability to absorb and emit infrared radiation, contributing to the greenhouse effect.

3. **Analyzing the Options:**
- The question provides four options: Methane, Carbon Dioxide, Chlorofluorocarbons, and Nitrogen.
- It is essential to identify which of these gases does not contribute to the greenhouse effect.

4. **Evaluating Nitrogen:**
- Nitrogen (N₂) is the most abundant gas in the atmosphere, making up about 78% of the air we breathe.
- Unlike the other gases listed, nitrogen does not have the capability to absorb infrared radiation. Therefore, it does not contribute to the greenhouse effect.

5. **Conclusion:**
- Based on the analysis, the gas that is not involved in the greenhouse effect is Nitrogen (Option D).

**Final Answer:**
- The gas which is not involved in the greenhouse effect is Nitrogen.
