green house effect :: essays research papers

GREEN HOUSE EFFECT creationIn temperate countries some economic solelyy important plants that cannot grow external at a very low temperature during the winter atomic number 18 cock-a-hoop in screwball-walled & glass-roofed growth chambers (known as glass abodes)exposed to sun. Glass houses are also used in sub tropiacal regions during winter months & relatively refrigerant high altitude for high value horticultural annual crops including flowers on a cmmercial scale as well as for research piddle especially for breeding of new varities & crop physiological & pathological studies. Temperature inside the glass house rises because of the glass of the roof & walls through it allows entry of sun exonerated with little obstruction, urge on the escaping of the reflected light of longer wave-lengths rich in infra-red rays resulting in a heat built up. Such glass houses are called green housesas the light & heat within such houses prove very effective for generous growth of green pla nts. The property of trapping heat by light speed di oxide & other gases of the atmosphere is similar to the glass cover of green house that reasists the escaping ofheat radiated from inside of the house.As such, these atmospheric gases are called green house gases that resist the escaping of radiated heat from the humanity by absorbing infra red rays & curiously reflecting the trapped heat back to earths surface.this phenomenon is therefore called the green-house effect in wicch sealed atmospheric gases act in a manner similar to the glass cover of glass house,as earth itself act as a green-house. major GREEN HOUSE GASESThe major sources of green house gases are (i)CARBON DI OXIDE - It comes from yearning of fossil fuels &from deforrestation. (ii)METHANE- It comes from paddy field,burning of wood,wetland etc. (iii)CHLOROFLURO CARBONS -which is populary known as CFC. It comes from air learn industry,foam packaging industries. (iv)NITROUS OXIDE-It comes from coal burning,motor veicheles,breakdown of chemial fertilizer,biomass burning.Carbon-di-oxide is the major green-house gas responsible for more than 55% of the green-house-effect. Methane is responsible for 20%,CFC is responsible for 15% & NO is responsible for 5% of the green-house effect.If the amount of carbon-di-oxide & other green-house gases would increase in the atmsphere ,the temperature on the surface of the earth & that of the layers of air adjuscent to the surface would increase,on the other hand international temperature would increase with the decrase in amount of the green house gases in the atmosphere.In fact the amount of all the green-house gase in the atmosphere is gradually increasing, as a result of which it is predicted that the global temperature would increase & there would be climatic changes on the earth resulting in adverse effects on the ecosystem of earth.
