How are the layers of the atmosphere different?
: 0 this is a midterm question, and no i'm not cheating, it's gonna be on the midterm

The atmosphere is divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space

In order, we have the:
Troposphere: contains all life and support all life on Earth
Stratosphere: contain the ozone layer, very cold but warms up as it gets higher
Mesosphere: temperature drops again and is the coldest place on Earth, most meteorites burn up in this layer
Thermosphere: the hottest layer, reaching to about 1000-1500 degrees celsius
Exosphere: highest layer, extremely low-density hydrogen, and helium composition
