| What causes uneven heating of earth? | angle of sunlight |
| cold air sinking; calm weather | high pressure |
| converging winds; hot air rises | low pressure |
| heat rises, cool sinks | convection current |
| hot air | less dense |
| cool air | more dense |
| caused by weight of air molecules above | air pressure |
| curved winds due to Earth's rotation | Coriolis Effect |
| what causes wind | cool air fills space left by rising warm air |
| low pressure along equator; no wind | Doldrum |
| high pressure at 30* N/S; no wind | Horse Latitudes |
| air cools and sinks at 30* N/S- blows East to West | Trade Winds |
| blows west to east; brings our weather | Prevailing Westerlies |
| cold, dense air sinks away from poles | Polar Easterlies |
| boundary between air masses of different temperatures | Jet Stream |
| night breeze caused by land cooling | land breeze |
| day breeze caused by warm air over land | sea breeze |
| day breeze caused by heating of mountain tops | valley breeze |
| night breeze caused from cooling of mountain tops | mountain breeze |
| dry side of the mountain | leeward side |
