We measure air pressure in (hectopascals/degrees).
Lines joining places of equal pressure are known as
(isotherms/isobars).
The difference in pressure between two places is known as
the (pressure gradient force/pressure force).
Winds always blow from a (low/high) pressure to (high/low)
pressure.
The isobaric interval on in the sketch is (four/eight)
hectopascals.
Air that subsides on the surface of the earth creates a
high pressure, and so (convergence/divergence) takes
place.
