  1. Magnetosphere
    Magnetic field generated by motion within the earth's core. Located 70,000 km above the earth's surface
  2. Auroras
    • occur when energy in the magnetosphere is radiated
    • Occur 50-75 miles above Earth's surface
    • Aurora Borealis
    • Aurora Australis
  3. Density and pressure are inversely related to altitude
  4. Ozonosphere
    • Increased levels of O3
    • Absorbs UV light and re-radiates longer wavelengths
  5. Ionosphere
    • Absorbs cosmic rays, X-rays, and Shorter wavelengths of UV radiation.
    • Contains Auroral Lights
  6. Troposphere
    • 0-18 km
    • 90% of atmosphere's mass
  7. Tropopause
    Acts as a lid because of warmer conditions in the stratosphere
  8. Stratosphere
    • located in the ozone layer 18 to 50km
    • Temperature increases with altitude
  9. Mesosphere
    • 50-80km
    • Temperatures decrease until the mesopause is reached
  10. Thermosphere
    • From 80-500 km
    • temperatures increase quickly
  11. Normal Lapse Rate
    • Average global cooling rate of the atmosphere
    • 6.4 C per 1000 m in the troposphere
  12. Environmental Lapse Rate
    lapse rate depends on local conditions
  13. Homosphere
    • inner atmosphere
    • 0-80km
  14. Heterosphere
    80-480km
  15. Constant Gases
    Nitrogen Oxygen and Argon 99% of atmosphere
  16. Variable Gases
    Carbon Dioxide, water vapor, and trace gases
  17. Natural factors that affect air pollution
    Wind, Local and Regional Landscapes, Temperature Inversions
