  1. 1Give one cause of acid rainburning fossil fuels
  2. 2why do people burn fossil fuelsthey give more energy
  3. 3what gases does fossil fuels givesulphur dioxide
    nitrogen oxide
  4. 4what is acid rainwhen the gases (Sulphur dioxide and Nitrogen Oxide) mix with the water vapour in clouds it falls as acid rain
  5. 5what are the main causes of acid raincars and power stations
  6. 6what is the ph of extreme acid rainph2
  7. 7what gas do cars producecarbon monoxide - a toxic gas
  8. 8what ph rain is acidicph below 5.6 is acidic
  9. 9give the 3 gases that make rain acidiccarbon dioxide
    sulphur dioxide
    nitrogen oxide
  10. 10what can acid rain do to the environmentkill fish
    corrode metals
    make statues dissolve
  11. 11give 3 ways of reducing acid rainburn less fossil fuels
    use geothermal energy
    use catalytic converters
  12. 12what are catalytic convertersthey are in a car, they convert harmful gases such as carbon monoxide into carbon dioxide, water and nitrogen.
  13. 13what percentage of gases is what in the atmosphere78% is nitrogen
    21% oxygen
    0.04% carbon dioxide
  14. 14natural pollutants are......naturally present
  15. 15what are pollutantsharmful gases
  16. 16what gases were normal millions of years agosulphur dioxide and carbon dioxide were normal
  17. 17how did the huge amounts of carbon dioxide in the atmosphere go awayplants evolved, absorbing co2 for their food making.
    other co2 was locked up sedimentary rocks
  18. 18what did the ozone layer form fromoxygen and more life also developed due to the ozone layer
  19. 19how did rivers and seas formthe earth temp cooled down, making hot air condense and turn into water.
  20. 20what was produced by volcanoes AND caused acid raincarbon dioxide and sulphur dioxide were produced by volcanoes
  21. 21why was oxygen considered a pollutantbecause most organisms weren't adapted to cope with huge amounts of oxygen
  22. 22why is carbon dioxide importantfor plants to photosynthesise and for sedimentary rocks to be made
  23. 23what does a catalytic converter turn nitrogen oxide intonitrogen
  24. 24what is climate changelongterm change in weather patterns
  25. 25what is global warmingwhen harmful gases are leaked into the atmosphere
  26. 26give the steps to greenhouse gas effect1. Sun heats up the earth surface
    2. earth produces radiation
    3. greenhouse gases like carbon dioxide absorb some of this radiation, and some goes back to space
    4. this keeps the earth warm
  27. 27what is deforestationcutting down trees
  28. 28what gives off 1/3 of methanecows fart and manure
  29. 29what is methaneMethane is a greenhouse gas that warms the earth up quicker than co2
  30. 30give 4 effects of global warming-the temp of sea waters are getting hotter
    -ice caps are melting
    -certain species are migrating
    -we are losing our food sources
  31. 31give 4 ways to measure pollution-ph of rain
    -monotoring stations
    -natural indicators (Lichen)
    -taking water samples from resovoirs
  32. 32what is lichen-combination of fungi and algi
    -they cant tolerate high rates of pollution
  33. 33why do we monitor pollutionso we can be aware
  34. 34which greenhouse gas is released in combustioncarbon dioxide
  35. 35which gas is not a greenhouse gasnitrogen
  36. 36what are hydrocarbonsatoms with only hydrogen and carbon
