Question

Quizplus · Accepted Answer

Greenhouse gases like carbon dioxide and methane absorb infrared radiation emitted by the Earth's surface and trap them in the atmosphere, leading to the warming of the planet's surface temperature. This phenomenon is known as the greenhouse effect. As the amount of greenhouse gases in the atmosphere increases, their ability to trap infrared radiation also increases, resulting in a rise in the planet's temperature.
