| Question | Answer |
|---|---|
| differences in air pressure | unequal heating |
| movement of air caused by differences in air pressure | wind |
| air is warmer and less dense than surrounding air | air pressure |
| the poles in colder and denser than surrounding air, it raised | sinks |
| high pressure areas are creaked around the poles as cold air | sinks |
| cold polar air flows towards | the equator |
| large,circular patterns of air movement | convection cells |
| bands of high pressure and low pressure, 30 | high pressure belt |
| paths of wind and ocean currents seem to curve | Coriolis effect |
| winds that blow from 30 latitude in both hemispheres | trade winds |
| area around the equator where the trade winds meets | doldrums |
| wind formed as cold, 60 north and south | polar easterlies |
| winds belt 30 and 60 | westerlies |
| sinking air creates high pressure and weak winds | horse latitude |
| marrow belts of high speed winds in upper and lower stratosphere | jet streams |
| local winds | mountain breeze |
| geographic features cause local winds | shoreline or mountains |
