global warming is the gradual increase in the temperature of the earth. Some gases lyk carbon dioxide , methane ,chlorofluorocarbon (CFC ), etc are present over the atmosphere lyk a blanket. These gases are know as green house gases and they trap the heat and make the earth warmer. The incoming heat of the sun or insolation comes to the earth in the form of short waves.These waves heat up the earth's surface. The earth re-radiates a part of this heat back to space. The re-radiated heat waves have a longer wavelength and thus gets trapped in the layer of green house gases. Thus a part ofthe heat is absorbed by the atmosphere and the other part is reflected back to earth surface and the surface of earth gets heated. In cold countries glass houses are made for plants. These houses traps the incoming solar heat and the inside of the glass house becomes warm suitable for the growth of plants.These houses are called green houses . The earth gets heated in a way similar to that of the green house and thus the process is called green house effect. Here the green house gases act as the glass of the green house.
