- evolution of atmo.
- phase 1
- 1.any atmosphere boiled away
- 2. a thin atmosphere formed but volcanos kept going
- 3.volcanoes gave out lots of gas: CO2, water vapour and nitrogen we think how atmo was formed
- 4. atmo. was probably mostly CO2 and water vapour with no oxygen
- 2. a thin atmosphere formed but volcanos kept going
- 1.any atmosphere boiled away
- phase 2
- 1. some green plants
- 2.lot of CO2 dissolved into sea
- 3.plants die and are buried naturally to produce coal
- 2.lot of CO2 dissolved into sea
- 1. some green plants
- phase 3
- 1.build up of oxygen killed of early lifeforms but caused others to evolve
- 2.no CO2 left now
- 1.build up of oxygen killed of early lifeforms but caused others to evolve
- Atmosphere today
- chemicals in atmo.
- Nitrogen:78% Oxygen:21% argon:1%
- humans are changing atmosphere
- pollutatnts: carbon dioxide,carb. monoxide, particulates, sulphur dioxide,
- come from vehicles, fuels, power stations, nature
- pollutatnts: carbon dioxide,carb. monoxide, particulates, sulphur dioxide,
- chemical reactions
- use diagrams to rep. molecules
- everything is made of tiny things called atoms
- when to atoms go together they make a molecule
- chemical reactions happen when they are re-arranged
- no atoms are ever destroyed
- Fossil fuels
- hydrocarbons
- formed from dead plants,animals
- coal is not a hydrocarbon
- oxidisation
- combustion
- chemical reactions

- carbon pollution
- carbon dioxide
- 2 molecules of oxygen and 1 carbon
- reacts using photosynthesis
- 2 molecules of oxygen and 1 carbon
- carbon monoxide
- 1oxygen 1 carbon
- produced instead of oxidisation
- 1oxygen 1 carbon
- particulate carbon
- 1. fly into the atmoshpere
- 2. fall back down as soot
- 1. fly into the atmoshpere
- sulphur So2 pollution
- comes from impurities in fuels
- extracted leftovers e.g. coal
- 1. fly into the atmoshpere
- 2. fall back down as soot
- acid rain
- comes from impurities in fuels
- carbon dioxide
- chemicals in atmo.
