The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat from the sun, keeping the planet warm enough to support life. Sunlight warms the Earth's surface, which then radiates heat back as infrared radiation; greenhouse gases like carbon dioxide and water vapor absorb this heat and re-radiate it, preventing it from escaping into space.
