Earth’s Atmosphere: Main Ideas
1) What is air pressure? (pg. 234-235)
a) The amount of pressure that air
molecules are exerting on the
molecules below them.

2) How does temperature affect air pressure? (pg.
236-237)
a) When temperature increases, air pressure
decreases. When air temperature decreases,
air pressure increases.
 Quick Check (pg. 237)
-How does altitude affect air pressure?
a) The higher the altitude the lower the air
pressure. The lower the altitude the higher the air
pressure.
