Green house effect is increasing due to

Options

A. High concentration of `NO_(2)`
B. High concentration of `SO_(2)`
C. High concentration of `CO_(2)`
D. High concentration of CO

Answer

**Step-by-Step Solution:**

1. **Understanding Greenhouse Effect**: The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat from the sun, preventing it from escaping back into space. This process is essential for maintaining the Earth's temperature and supporting life.

2. **Role of Solar Radiation**: The Earth receives solar radiation from the sun. Some of this radiation penetrates the atmosphere and heats the Earth's surface.

3. **Reflection and Absorption**: A significant portion of the incoming solar radiation is reflected back into space, but some of it is absorbed by the Earth, contributing to its warmth.

4. **Greenhouse Gases**: The heat that is absorbed by the Earth is partially trapped by greenhouse gases present in the atmosphere. These gases include carbon dioxide (CO2), methane (CH4), chlorofluorocarbons (CFCs), and nitrous oxide (N2O).

5. **Contribution of Different Gases**:
- Carbon Dioxide (CO2) contributes approximately 60% to the greenhouse effect.
- Methane (CH4) contributes about 20%.
- Chlorofluorocarbons (CFCs) account for around 14%.
- Nitrous Oxide (N2O) contributes the remaining 6%.

6. **Increasing Concentration of Greenhouse Gases**: The greenhouse effect is increasing primarily due to the rising concentration of these greenhouse gases, especially carbon dioxide, in the atmosphere. This increase is largely attributed to human activities such as burning fossil fuels, deforestation, and industrial processes.

7. **Conclusion**: Therefore, the greenhouse effect is increasing due to the elevated levels of greenhouse gases, particularly carbon dioxide, which trap more heat in the atmosphere and contribute to global warming.
