1. Layers of the Atmosphere

2. Troposphere The lowest layer of the atmosphere
Weather, clouds, and air pollution are found

3. Stratosphere Above the troposphere
Contains ozone (a layer of gas that protects life on Earth from the sun’s harmful ultraviolet rays)

4. Mesosphere The third layer and the coldest part of the atmosphere
Rock fragments from space “burn up” and protect earth

5. Thermosphere Temperatures are extremely high due to the sun’s rays
The air is very thin that high up

6. Exosphere The highest (and last) layer of the atmosphere
There are fewer and fewer molecules the higher you go until they escape into space
