How greenhouse effect is formed?
Green house effect was formed from the accumulation of gases like C,methane,nitrous oxide,etc in the atmospher and form a blanket coverage to the underneath earth.These gases have high capacity of trapiing or holding the out going long wave radiation.When this radiation is traped before escaping the lower atmospher it increases the temprature of the earth environment.Increasing in environmental temprature causes melting of the polar ice,increasing in volum of the ocean and sea water,overflooding,unseasonal rainfall due to high evaporation and condensation in the atmospher for areas far from ocean and sea…This inturn affect human settelement,animal life and habitate,crop production, transportation etc.From the mentioned gases nitrous oxide is the most dangrous in traping radiation (200x> CO2) and methane is the second(28).
