AIR PRESSURE

100

is traditionally measured in which two units

millibars; atmospheres

instrument that measures air pressure

barometer

300

this happens to air pressure as altitude increases

decreases

400

as the density of air increases, the air pressure does this

decreases

500

once past the exosphere, you are now in the ____ of space (think negative pressure)
