Notes: Air Pressure
Air Pressure—the force per unit area of air’s weight (due to gravity) on Earth’s surface
Air moves from areas of high pressure (hot areas like Earth’s surface) to areas of low pressure (colder areas like the atmosphere), creating wind◦Air pressure decreases with
increased altitude

Notes: Coriolis EffectCoriolis effect—tendency of an
object moving over Earth’s surface (airplane, rocket, wind) to curve away from its path of travel◦Caused by Earth rotating◦Therefore, objects curve to the right
in the Northern hemisphere and to the left in the Southern hemisphere

Notes: FrictionFriction—force resisting surface
winds◦Rough land=more friction=move
slower=more deflection from Coriolis effect (and vice versa)
◦Higher altitude=less friction=move faster=less deflection from Coriolis effect (and vice versa)
