The Atmosphere Flashcards
Name the layers of the atmosphere
Thermosphere
Mesosphere
Stratosphere
Troposphere
What is the limit of the troposphere
It stops at the tropopause
Average 11km (Altho changes depending on where on earth)
What is the limit of the mesosphere?
The mesopause
Around 80km from earth’s surface
What is the limit of the stratosphere
The stratopause
Around 50km from the earth’s surface
What is within the stratosphere
Ozone which is Oxygen 3 molecules
What is the thermosphere
The furthest most layer of the atmosphere, extending into space
What is an ISA
International Standard Atomosphere
Mean sea level temp
15°C
Mean sea level pressure
1013.25 hPa
Mean sea level density
1.225 kg/m³
Temperature lapse rate
1.98 (2) °C per 1000ft
This goes up to a tropopause constant of -56°C
Tropopause altitude
36090ft (36,000)ft
Pressure lapse rate
27ft / hPa
Density lapse rate
A non linear rate
22,000 ft is 50%
40,000 ft is 25%
