Troposphere

1. Closest to earth/ smallest
2. Weather (water vapor/ carbon dioxide)
3. Nitrogen, oxygen
4. Clouds
5. Airplanes
6. Altitude increase colder

5

• Turn to your partner. The person who is taller
  tell their partner what happens to the
  temperature as you go up in the troposphere.
• (15 seconds)
• Report back to class

Stratosphere

1. Ozone layer
2. Ozone is a form of oxygen
3. Nitrogen, oxygen
4. Cold until you get to the ozone layer

7

• Turn to your partner. The person who is shortest
  tell their partner one characteristic of the
  stratosphere.

Air Pressure

1. Is greatest near the surface of the earth in the
   troposphere.

16
Air Pressure

1. Air pressure decreases as you get farther from
   the earth because there is less gravity

17

• Turn to your partner. Explain what happens to air
  pressure as you go up in the atmosphere.
