Closest layer to earth

highest layer

Hottest layer

Coldest layer

Oldest layer

has alot of air

air density=no air, we think of it as outer space, space shuttles orbit Earth here

air density=low, we normally think of it as outer space, space shuttles orbit Earth here

air density=high, we don't think of it as outer space, space shuttles don't orbit Earth here

Highest and thinnest layer

biggest and lowest layer

merges with outer space

coldest layer

active part of atmosphere that grows or shrinks depending on the energy from the sun, overlaps 3 layers:mesosphere, thermosphere, and exosphere

5th layer

not active part of atmosphere that doesn't grow or shrink depending on the energy from the sun, overlaps 3 layers:ozone layer, thermosphere, and exosphere

4th layer
