Transcript of Atmosphere

Layers of the atmosphere
Troposphere
Stratosphere
Mesosphere
Thermosphere
Contains 75% of all atmospheric molecules
Contains 24% of all atmospheric molecules
Contains few molecules
Made up of two parts
Unit 4
15 degrees C
- 60 degrees C
altitude = 0 - 12 km
Air pressure is HIGHEST
Weather
Clouds
altitude = 12 - 50 km
- 60 degrees C
- 5 degrees C
Ozone Layer
altitude = 50 - 80 km
- 5 degrees C
- 90 degrees C
Meteors
Air pressure
decreases
Air pressure continues
to decrease
Ionosphere
Exosphere
Ionosphere
Even fewer molecules
Molecules in this layer have the hottest temperature, but
they are spaced so far
apart that the layer
itself would not feel hot.
-90 degrees C to -60 degrees C
Air pressure continues to decrease
altitude = 80 - 550 km
Space shuttles
Aurora
Borealis
Exosphere
Fewest molecules
altitude = 550 km - outer space
Coldest layer
Lowest air pressure
Satellites orbit
