The correct Answer is:
To determine the percentage of methane in the atmosphere, follow these steps: 1. **Understand the Context**: Methane is recognized as a greenhouse gas, which plays a significant role in regulating the Earth's temperature. 2. **Identify the Greenhouse Gases**: The main greenhouse gases include carbon dioxide (CO2), methane (CH4), chlorofluorocarbons (CFCs), and nitrogen oxides (NOx). 3. **Recall the Percentages**: From the information provided, we need to remember the approximate percentages of these gases in the atmosphere: - Carbon Dioxide (CO2): 60% - Methane (CH4): 20% - Chlorofluorocarbons (CFCs): 14% - Nitrogen Oxides (NOx): 6% 4. **Select the Correct Answer**: Based on the percentages mentioned, the percentage of methane in the atmosphere is 20%. Therefore, the correct option is C (20%). 5. **Conclude**: The final answer to the question regarding the percentage of methane in the atmosphere is 20%.
