Unit 3 Lesson 4
| Question | Answer |
|---|---|
| wind | movement of air caused by differences in air pressure |
| Coriolis Effect | the curving path of wind due to Earth's rotation |
| global winds | wind systems that occur at or near the Earth's surface and travel long distances worldwide |
| trade winds | global winds that blow and curve to the west between the equator and 30 degrees latitude in both hemispheres |
| westerlies | global winds that blow and curve to the east between 30-60 degrees latitude in both hemispheres |
| polar easterlies | global winds that blow and curve to the west between 60-90 degrees latitude in both hemispheres |
| doldrums | where trade winds of both hemispheres meet (around equator) and very little wind occurs |
| horse latitudes | an area around 30 degrees latitude where air stops moving and sinks |
| jet streams | a global wind with narrow belts of high-speed wind that blow west to east just above the troposphere |
| subtropical jet stream | a jet stream that brings warmer air from the equator |
| polar jet stream | a jet stream that brings colder air from the poles |
| local winds | movement of air over short distances that occurs in specific locations due to the geography of the land |
| sea breeze | a local wind breeze that occurs during the day as the cool air from the sea replaces warm air above land |
| land breeze | a local wind breeze that occurs at night when the cooler air above land replaces the warmer air above the sea |
| valley breeze | a local wind breeze that occurs during the day as the cool air from a valley replaces the warm air above a mountain |
| mountain breeze | a local wind breeze that occurs at night as the cool air from the mountain replaces the warmer air above a valley |
