understand how human activities contributre to greenhouse gases
1. the burning of fossil fuels results in the formation of carbon dioxide nitrous dioxide and sulphur dioxode
carbon dioxide and nitrous dioxide are greenhouse gases (absorb infra red light and distribute it back in all directions, but crucially towards the earths surface
these are released from factories and vehicles-exhaust emissions. burning of coals in domestic facilities, although that is less prominent now
2. farming
animals in their digestion of crops emit methane gas into the atmosphere. cows are mainly the blame. 9 percent of methane blamed on farm animals
3. evaporation of water to form water vapour, clouds are a significant contributer to the greenhouse effect
4. refrigiration, solvents anmd propellents contain CFC's
CFC's--> chlorofluorocarbons
C, Cl (small 3) F
well associated with UV LIGHT and CATALYSING THE BREAKDOWN OF THE OZONE LAYER
