• Nitrogen and Oxygen most abundant
- Helium, hydrogen, argon, and carbon dioxide
___ ____ Pollutants consist of auto exhaust, factory waste, dust, & bacteria.
______ of the atmosphere decreases as altitude increases.
@ __ miles - – atmosphere is too thin to support life
@ __ miles – atmosphere is too thin to support combustion
What is the weight of 1sq. inch of air at a given altitude?
- Equivalent to 14.69 PSI
Atmospheric Pressure @ SEA-LEVEL:
For every 2,343 feet traveled in altitude;
atmospheric pressure is increased or decreased 1 PSI.
Inches of Mercury is also a measurement just like _ _ _.
• 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”)
• Extends from 6-60 miles
+ Temperature in the stratosphere is affected by the ozone.
• Extends from 12-30 miles
- Composed of Poisonous Gas
- Filters Ultraviolet Rays
- Temperature Increases above ozone
+ Unblocked radioactive energy
+ 77 Centigrade at 30miles
+ 2270 Centigrade at 55miles
• 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
