Here's a breakdown of the layers of the atmosphere:

* Troposphere: The lowest layer, where we live, and where weather occurs.

* Stratosphere: Contains the ozone layer, which protects us from harmful UV radiation.

* Mesosphere: Characterized by decreasing temperatures and where most meteors burn up.

* Thermosphere: The hottest layer, where the International Space Station orbits, but also very thin air.

* Exosphere: The outermost layer, where the atmosphere gradually fades into space.
