The Atmosphere - Chapter 1: Extent and Structure of Atmosphere Flashcards
The weight of the air above
Atmospheric pressure
True or false: the spot where the atmosphere ends and space begins is finite and definite and has no room for nuance.
False
Name the four layers of the atmosphere:
Troposphere, stratosphere, mesosphere, thermosphere
How many layers of atmosphere are there?
Four
The bottom layer of the atmosphere, where temperature decreases with an increase in altitude
Troposphere
The chief focus of meteroroloists since it is where most weather occurs
Troposphere
Layer just beyond the troposphere
Stratosphere
Layer closer to us than stratosphere
Troposphere
The boundary between the troposphere and stratosphere
tropopause
As the troposphere extends, the temperature ____
decreases
The temperature decrease in the troposphere is called
Environmental lapse rate
About halfway through the stratosphere, the temperature begins to ____
increase
Between the stratosphere and mesosphere
Stratopause
The ozone of the atmosphere is concentrated in the
Stratosphere
Why is the stratosphere warmer than the top of the troposphere?
Ozone predominantly resides there, and ozone absorbs heat from the sun
The third layer where the temperature dereases again
Mesosphere
Space between mesosphere and thermosphere
Mesopause
True or false: the thermosphere contains a large fraction of the atmosphere’s mass
False
True or false: the thermosphere has a dramatic and defined upper limit
False
The fourth layer of atmosphere that has a low density
Thermosphere
The temperature begins to _____ in the thermosphere due to the energy of oxygen and nitrogen atoms
increase
