1. Layers of the Atmosphere Divided depending on Temperature
How many layers are there in the atmosphere?
There are 5 layers, the troposphere, stratosphere, mesosphere, thermosphere, and exosphere,

3. Layers of the Atmosphere
Troposphere:
- This is the layer we live in and the smallest layer
Temperature decreases as altitude increases 140 to -76 degrees F. WHY?
All weather happens here
This is the ONLY layer living things can live in
8 miles above sea level

4. Layers of the Atmosphere
Stratosphere:
Temperature increases as altitude increases from -76 to 32 degrees F
Ozone layer found here, volcanic particulates
Weather Balloons
8-30 miles above the earth

5. Layers of the Atmosphere
Mesosphere:
- Temperature decreases to coldest point 32 to -130 degrees F.
- Meteor Showers
miles

6. Layers of the Atmosphere
Thermosphere:
- Temperature increases 2700 degrees F
- Aurora borealis (Northern lights), International Space Station, Space Shuttle stay in this layer.
miles from sea level

7. Layers of the Atmosphere
Exosphere:
- Temperature Increases to 5000 degrees F
- Satellites orbit here
- 120 miles + from sea level
Meteorology - is the study of the earths atmosphere
