Front (Question)

Structure of Earth's Atmosphere + PICTURE

Back (Answer)

exosphere

low density; fades into space
hottest layer; gas extrememly rarified, provides noticable drag on satellites
hto enough and high enough that atmos can escape

thermosphere

temp begins to rise at the top
Absorbes heat via solar x-rays which ionizes all gases
Contains ionosphere, which reflects back humans radio signals

stratosphere - ozone

lies above the greenhouse gases (no IR absorption
Absorbes heat via Solar UV photons, which dissociate ozone O₃
UV penetrates through top layer; colder air is above hotter air
no convection or weather, the atmosphere is stratified

troposphere

layer closest to surface
absorbes IR from surface
temp drops with altitude
Where weather happeans
Hot air rises and high gas density causes storms (convection)
