Detailed explanation-1: -Carbon dioxide is called a greenhouse gas because it is one of the gases in the atmosphere that warms the Earth through a phenomenon called the greenhouse effect. Carbon dioxide molecules in the atmosphere absorb long-wavelength infrared energy (heat) from the Earth and then re-radiate it, some of it back downward.
Detailed explanation-2: -Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth. This heats up the atmosphere and raises the planet’s average temperature.
Detailed explanation-3: -Carbon dioxide, for example, absorbs energy at a variety of wavelengths between 2, 000 and 15, 000 nanometers-a range that overlaps with that of infrared energy. As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions.
