What it the relationship between altitude and atmospheric pressure? As altitude increases the the pressure _______
decreases
increases
there is no change
It depends on the latitude
What is atmospheric pressure?
The force exerted on a surface by the humidity above it
The force exerted on a surface by the air above it
The force exerted on a surface by the air below it.
The weight of the air pressing against an object
Name of the instrument used to measure atmospheric pressure is called a (a) .
All are parts of the mercury barometer:
glass tube
mercury
vessel filled with mercury
vacuum
gradings in oC or oF
The simple mercury barometer, how does it work
the mercury in the column exerts a force on the vessel at the bottom. The new level is the atmospheric pressure
The pressure exerted by the atmosphere forces mercury into the glass tube. This shows the atmospheric pressure.
The length of the vacuum in the glass tube is measured to give the atmospheric pressure
The volume of mercury in the vessel below is measured to tell the air pressure
The length of the mercury in the column is measured in ______
mm, cm or inches
ml, L
mg, g
cm2
Unit of atmospheric pressure
MB
millibars
mm
millimeters
cm
m
A high pressure occurs if the reading in the barometer is (a) MB
A line drawn on a map that connects places having the same pressure?

with
downward
Which flow is associated with high pressure systems?
