2AtmosphereThe 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.
