Definition of Greenhouse Effect

The greenhouse effect is a natural phenomenon that results in the heating of the Earth’s surface. The gases of the greenhouse include carbon dioxide (CO2), water vapours, methane (CH4), nitrous oxide (N2O), ozone (O3), and a relative number of CFCs. The radiations from the sun reach the atmosphere of the Earth. Some of these radiations are absorbed by the oceans as well as by land while others are re-radiated by the gases of the greenhouse and some are reflected into space.


The absorption of the radiations results in the heating of the atmosphere which makes Earth suitable for the existence of life. The temperature of the earth is increasing rapidly due to immense human activities like the burning of fuels, land clearing, etc which are emitting great amounts of greenhouse gases.
