Name the two gases contributing maximum to the green house effect.

Explanation

**Step-by-Step Solution:**

1. **Understanding Greenhouse Effect**: The greenhouse effect refers to the process by which certain gases in the Earth's atmosphere trap solar energy, preventing it from escaping back into space. This leads to an increase in the Earth's surface temperature.

2. **Identifying Key Gases**: The two primary gases that contribute significantly to the greenhouse effect are:
- **Carbon Dioxide (CO2)**: This gas is released into the atmosphere through various human activities, including respiration, burning fossil fuels, and deforestation.
- **Methane (CH4)**: Methane is another potent greenhouse gas that is released from agricultural practices, landfills, and other human activities.
