- Module C1 Air Quality
- The evolution of the atmosphere
- PHASE 1: VOLCANO
- gave out gases like;
- Water vapour
- Oceans formed when water vapour condensed
- Carbon Dioxide
- Which formed the atmosphere
- Water vapour
- Oceans formed when water vapour condensed
- Nitrogen
- Water vapour
- Which formed the atmosphere
- Nitrogen
- Water vapour
- gave out gases like;
- PHASE 2: GREEN PLANTES
- Plants evolved over most of the earth
- Taking in carbon dioxide and emitting oxygen
- Via photosynth-esis
- When they died the carbon they absorbed was trapped in rocks
- Creating fossil fuels
- Taking in carbon dioxide and emitting oxygen
- Plants evolved over most of the earth
- PHASE 1: VOLCANO
- The atmosphere today
- 78% nitrogen
- 21% oxygen
- 1% argon
- small amounts of other gases
- Human activity adds pollutants to the air
- carbon dioxide
- Carbon monoxide
- particulates
- sulphur dioxide
- nitrogen oxides
- Can be directly hazardous to humans
- sulphur dioxide
- nitrogen oxides
- Can be directly hazardous to humans
- particulates
- Carbon monoxide
- carbon dioxide
- Climate change
- Or damage the environment
- particulates
- nitrogen monoxide
- happens in high temps
- can continue to make nitrogen dioxide
- acts similarly to sulphur dioxide
- nitrogen monoxide
- happens in high temps
- can continue to make nitrogen dioxide
- acts similarly to sulphur dioxide
- acts similarly to sulphur dioxide
- nitrogen monoxide
- acts similarly to sulphur dioxide
- Can be directly hazardous to humans
- Acid Rain
- nitrogen oxides
- Or damage the environment
- sulphur dioxide
- Can be directly hazardous to humans
- Acid Rain
- nitrogen oxides
- sulphur dioxide
- particulates
- Climate change
- Carbon monoxide
- carbon dioxide
- Air Pollution
- Fossil fuels
- Coal
- Oil
- CARBON
- Coal
- Gas
- carbon dioxide - greenhouse effect
- carbon monoxide - poisonous
- particulates - soot
- CARBON
- Gas
- hydrocarbon - except coal
- burning fuel = oxidation
- Fossil fuels
- Chemical Reactions
- all substances are made from atoms
- when these are joined together they make molecules
- happen when atoms are rearranged
- Reactants
- rearrange themselves into
- Products
- rearrange themselves into
- No mass is lost
- Reactants
- all substances are made from atoms
- Reducing Pollution
- cars
- catalytic converters
- reduction (nitrogen monoxide)
- oxidation (carbon monoxide)
- biofuels and electric cars
- catalytic converters
- Power stations
- removing sulphur dioxide from flue gases
- seawater
- dissolves
- produces carbon dioxide, water and dissolved sulfate
- dissolves
- an alkaline slurry
- calcium oxide reacts with it to produce a solid waste product
- calcium sulfite
- calcium oxide reacts with it to produce a solid waste product
- seawater
- removing sulphur dioxide from flue gases
- cars
