What are the different layers of the atmosphere?

Here are the layers of the Earth’s atmosphere in brief, listed from the closest to the Earth to the furthest away:

  1. Troposphere: the lowest layer, where weather occurs and where we live and breathe.
  2. Stratosphere: contains the ozone layer that protects us from harmful UV radiation.
  3. Mesosphere: the layer where meteors burn up upon entry into the atmosphere.
  4. Thermosphere: the layer where the auroras occur and where the International Space Station orbits.
  5. Exosphere: the outermost layer that gradually fades into space.
