SSC MTS EXAM

Detailed explanation-1: -Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth’s outgoing energy, thus retaining heat in the atmosphere.

Detailed explanation-2: -Carbon dioxide. Carbon dioxide (CO2) is the most significant greenhouse gas. Natural sources of atmospheric CO2 include outgassing from volcanoes, the combustion and natural decay of organic matter, and respiration by aerobic (oxygen-using) organisms.

Detailed explanation-3: -Methane is a very potent greenhouse gas. Greenhouse gases (GHG) affect the Earth’s temperature and climate system. They absorb some frequencies of infrared radiation emitted from the Earth’s surface, trapping heat in the atmosphere that would otherwise go out into space.
