All None

Ignore?
thickness of atmosphere
less than 2% of earth's thickness
pressure and unit
force exerted/unit area (weight above you)
pressure gradient
pressure difference between 2 locations divided by the distance between those 2 locations
P=pTR
equation of state
vertical pressure distribution
Determined by hydrostatic equilibrium
Pressure decreases with height
how does pressure change with height
hydrostatic equilibrium
pressure decreases with height because downward gravity force is balanced by vertical pressure gradient
troposphere
the lowest portion of Earth's atmosphere; contains approximately 75% of the atmosphere's mass and 99% of its water vapor and gasses.
geostrophic balance
Simple balance between pressure gradient force and Coriolanus force
troughs
low pressure areas
ridges
high pressure areas
