Greenhouse Effect

The greenhouse effect is a natural process that occurs when certain gases in the Earth's atmosphere trap infrared radiation from the sun that is reflected off the Earth's surface. This trapped radiation warms the Earth's surface, which is essential for supporting life on the planet. However, human activities have significantly increased the concentration of these greenhouse gases, leading to a phenomenon known as global warming.

Greenhouse Gases

The main greenhouse gases responsible for the greenhouse effect are carbon dioxide (CO2), methane (CH4), water vapor (H2O), and nitrous oxide (N2O). These gases are naturally present in the Earth's atmosphere, but human activities such as burning fossil fuels and deforestation have increased their concentrations, leading to global warming.

Pair of Gases for Greenhouse Effect

The pair of gases that is mainly responsible for the greenhouse effect is carbon dioxide and methane. These two gases are the most important contributors to global warming, as they have a significantly higher potential to trap heat than other greenhouse gases.

Carbon dioxide is released into the atmosphere through the burning of fossil fuels such as coal, oil, and gas. It is also released through deforestation and other land-use changes. Methane, on the other hand, is produced by a variety of natural and human activities, including the decomposition of organic matter in landfills, agriculture, and livestock farming.

Conclusion

In conclusion, the pair of gases that is mainly responsible for the greenhouse effect is carbon dioxide and methane. The increase in their concentration in the Earth's atmosphere due to human activities has led to global warming, which has significant implications for the planet's ecosystems and human societies.
