    12 Miles
  6. What is the weight of 1sq. inch of air at a given altitude?
    Atmospheric pressure
  7. - Equivalent to 14.69 PSI
    Atmospheric Pressure @ SEA-LEVEL:
  8. For every 2,343 feet traveled in altitude;
    atmospheric pressure is increased or decreased 1 PSI.
  9. Inches of Mercury is also a measurement just like _ _ _.
    PSI
  10. • Extends from ground level to approximately 6 miles

    -Constant decrease in temperature

    + -55 degrees Celsius at 6 miles (altitude)  
    Contains ¾ total weight of the atmosphere
    Troposphere (Comes first “trophy”)
  11. • Extends from 6-60 miles

    + 2270 Centigrade at 55miles
    Ozone Layer
  13. • Found primarily in the troposphere
    Fog and Water Vapor

    -Measured by relative humidity (is the ratio of moisture in the air compared to what it could hold at that temperature and pressure)

    -Also can be found in the lower level of the stratosphere
    Moisture in the Atmosphere
