  1. Air Pressure By Mrs. S. Deringer

  2. Air Has Mass I knew I shouldn’t have eaten all that air. AIR AIR

  3. What is in the Air? People generally believe that air is composed mostly of oxygen. In fact, they frequently use the terms "air" and "oxygen" interchangeably. This is a misconception. The content of oxygen in the air is relatively small when compared to the gas nitrogen.

  4. Air Pressure is . the force that air molecules push down on a surface. AIR AIR AIR Hey!! Get away from me! AIR AIR It’s all around us. . . Like it or not… AIR AIR AIR

  5. Air Pressure is . . .

  6. Air Pressure. . . . is not the same everywhere on earth.

  7. 3 Things that affect Air Pressure are Humidity Altitude Temperature

  8. Temperature Air pressures decreases whenever, or increases. Humidity Altitude

  9. Temperature Affects Air Pressure lower Warmer air brings ______ air pressure.

  10. Temperature Affects Air Pressure

  11. Altitude Affects Air Pressure As the altitude the air pressure increases decreases The people at the bottom of the pyramid can feel all the weight and pressure of the people on top (high pressure). The person on the top doesn’t feel any weight (less pressure)

  12. Humidity Affects Air Pressure In addition to gases, the air also contains moisture. As the humidity or moisture in the air increases the air pressure decreases

  13. fast In Low Air Pressure, the air molecules are moving and are apart. far

  14. slow close together In High Air Pressure, the air molecules are moving and are .

  15. Could Air Crush a Metal Tank Car ????? The inside of this tank car was washed out and cleaned with HOT steam. Then all the outlet valves were shut . The tank car was sealed. All the workers went home for the evening. In the morning when they returned this is what they found. This tank car was smashed, crushed, or collapsed by an unseen force why?

  16. As temperature increases . . As altitude increases . . As humidity increases . . Air pressure Air pressure Air pressure decreases decreases decreases

  17. Low Air Pressure L Low air pressure brings . PRECIPITATION

  18. High Air Pressure H High air pressure brings clear and weather. skies fair

  19. High and Low Pressure

  20. A is used to measureair barometer

  21. Barometer

  22. Air Pressure Review precipitation clear • A low pressure system brings ___________ weather. • A high pressure system brings __________ weather. • As the humidity or amount of moisture in the air increases the air pressure _________. • As the air temperature gets warmer the air pressure ___________. • The higher up you go air pressure ___________. • In high air pressure the air molecules are moving __________ and are _________________. • In low air pressure the air molecules are moving __________ and are ______________________. • A ____________________ measures air pressure. decreases decreases decreases slow close together fast far apart barometer
