Methane CH4

Water Vapour H2O

Chlorofluorocarbons (CFC's) and nitrogen oxides

Sources of greenhouse gases:
Methane from paddy feilds - it is produced by the baterial decomposition of vegetation under water that occurs in flooded rice fields

Cattle-cows, etc. have four stomach and In the complicated process of digesting the grass the food is femented, producing large quantaties of methane gas as a by-poduct which the cow expels.

Water vapour is always present in the atmosphere by the evapouration of the oceans and lakes as part of the water cycle- (water vapour traps heat! )

Carbon Dioxide- It is produced naturally during respiration but the main source is the combustion of fossil fuels and the burning of rain forests and plant life.

Nitrogen Oxides- During combustion of hydrocarbons and also over use of artifical fertilizers.

Influences of Greenhouse Gases on Global Warming:
Particulates have the opposite effect as greenhouse gases. They can lower the temperature by reflecting sunlight. These include soot and volcanic ash.
