How do differences in air pressure affect the movement of air?

• Air always moves from areas of high pressure to areas of low pressure.
• Air always moves from areas of low altitudes to high altitudes.
• Air always moves from areas of low pressure to areas of high pressure.
• Air always moves from east to west.
