The envelope of gases surrounding the Earth changes significantly with changes in altitude. Four unique layers of the atmosphere have been observed - each marked by its own temperature profile.
|Troposphere||Surface - 36,000 ft.||Temperature decreases with height|
|Vertical depth varies with seasonal temperature changes|
|Nearly all weather occurs in this region|
|Stratosphere||36,000 ft. - 31 mi.||Temperature increases with height|
|Mesosphere||31 mi. - 53 mi.||Temperature decreases with height|
|Thermosphere||53 mi. - 430 mi.||Temperature increases with height|
