The greenhouse effect is a naturally occurring phenomenon that is responsible for heating of Earth’s surface and atmosphere.
Green house gases are those that absorb and emit infrared radiation in the wavelength range emitted by earth.
Without the greenhouse effect the average temperature at surface of Earth would have been a chilly –18℃ rather than the present average of 15℃.
Most abundant greenhouse gases in Earth’s atmosphere are
Carbon dioxide
Methane
Nitrous oxide
Chlorofluorocarbons
Final answer:
Greenhouse gases are
Carbon dioxide
Methane
Nitrous oxide
Chlorofluorocarbons
