Exosphere - Layer 5: The layer found in space, where satellites orbit, Thermosphere - Layer 4: Nitrogen and oxygen absorb radiation making temperatures above 2000 ℃. This layer includes the ionosphere which is filled with charged ions that can radiate light (northern and southern lights), Mesosphere - Layer 3: Coldest layer of the atmosphere with temps reaching close to -100℃, Stratosphere - Layer 2: Temp rises as altitude increases because ozone in this layer absorbs UV from the sun, Troposphere - Layer 1: Layer nearest the Earth’s surface.
