    Automobiles
  2. True or false. The air in 2011 is much dirtier now than it was in 1980.
    False.
  3. The atmosphere was initially generated by a process called what?
    Outgassing
  4. What is the process of Outgassing?
    When rocks are heated up, they release gases.
  5. What are the 4 main atmospheric gases?
    • Nitrogen
    • Oxygen
    • Argon
    • Carbon Dioxide
  6. In radiation, what does Lambda represent?
    Wavelength
  7. What are the broad categories of the Electromagnetic Spectrum?
    • Radiowaves / TV Waves
    • Microwaves
    • Infrared
    • Visible Light
    • Ultraviolet
    • X-Rays
    • Cosmic Rays
    • Gamma Rays
  8. What are the three types of UV radiation?
    • UVA
    • UVB
    • UVC
  9. What is the relationship between Wavelength and Energy?
    Inversely proportional
  10. What does it mean when energy waves go through Scattering?
    Energy waves that are reduced, then bounced around in the atmosphere.
  11. What keeps our global temperature cool?
    Atmosphere
  12. What keeps the earth's surface warm at night?
    The scattering of Infrared light
  13. Most of the Greenhouse Effect is due to water in the atmosphere?
    Water Vapor
  14. What is the biggest contributor to the Greenhouse Effect?
    CO2
  15. What do you get when you add O2 + O. (radical)?
    O3 - Ozone
  16. True or false. Ozone is very stable.
    False. Ozone is very unstable.
  17. In what layor of the atmosphere is natural occurring Ozone located?
    Stratosphere
  18. In which layer of the atmosphere does Ozone become a pollutant?
    Troposphere
  19. Which layer of the atmosphere do we live in?
    Troposphere
  20. Which UV radiation breaks apart O3 to O2 and O radical?
    UVB
  21. Chloroflourocarbons (CFCs) were invented as what?
    A propellant
  22. When were CFCs used widely?
    1960s to 1970s
  23. How often does Chlorine destroy 100,000 Ozone molecules?
    10-15 years
  24. True or false. Bromoflourocarbons work just as well as CFCs.
    True.
  25. Why weren't BFCs used instead of CFCs?
    Because BFCs are much more expensive
  26. What was the problem with Bromine in relation to Ozone?
    It is much more efficient and it would have even more quickly eaten away at the Ozone layer.
  27. Where is the hole in the Ozone layer located?
    Over Antarctica
  28. What two countries does the hole in the Ozone layer adversely affect?
    • Australia
    • New Zealand
  29. Over 90% of nonmelanoma skin cancers are due to what kind of UV exposure?
    UVB
  30. Which city has the worst air quality of any city in the United States?
    Los Angeles
  31. What type of system sits over the LA Basin most of the year and pushes the air down?
    High Pressure System
  32. The High Pressure System diverts cold, rainy weather where?
    San Fransisco
  33. What is the negative aspect of High Pressure System?
    It keeps anything that we throw up into the air... like pollution
  34. What is the Environmental Lapse Rate?
    The air turns - 3.5 deg F every 1000 feet
  35. What happens to the Environmental Lapse Rate in a High Pressure System?
    Instead of air getting cooler as it rises, the air gets warmer
  36. What is the Inversion Layer?
    • Inverted meaning that instead of getting colder, air gets warmer due to increasing pressure.
    • Pressure = 1/Temp
  37. What we view as the smog line is actually what?
    The Inversion Layer
  38. True or false. There is a natural haze in the LA Basin due to the High Pressure System.
    True
  39. What can break up the High Pressure System temporarily?
    Strong wind like a storm
