What are Greenhouse Gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat. The main greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

How do Greenhouse Gases affect temperature?

Back

Greenhouse gases absorb and emit infrared radiation, leading to the greenhouse effect, which warms the Earth's surface.

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space and thus warming the planet.
