2. Atmosphere
The Earth is surrounded by a blanket of air, which we call the atmosphere.
It absorbs the energy from the Sun, recycles water and other chemicals and protects us from high-energy radiation.
The envelope of gas surrounding the Earth changes from the ground up. Four distinct layers have been identified using thermal characteristics (temperature changes), chemical composition, movement, and density.

3. Layers of the Atmosphere
Thermosphere—highest
Mesosphere
Stratosphere (contains ozone)
Troposphere---layer we live in
