12. Bands of high speed winds about 10 kilometers above the Earth’s surface jet stream
13. The distance north or south of the equator measured in degrees latitude
14. The curving of winds caused by the Earth’s rotation Coriolis Effect
15. Winds that blow steadily from specific places over long distances global winds
Multiple Choice: Shade the letter of the correct answer on the bubble sheet.
16. Local winds differ from global winds because they
A. are caused by unequal heating within a small area. ***
B. are caused by differences in cloud cover.
C. are due to unequal rainfall.
D. are not influenced by air masses.
17. The doldrums are characterized by
A. high pressure.
B. cool temperatures.
C. weak winds. ***
D. heavy air.
18. The horse latitudes are located
A. at about 60° north and south latitudes.
B. at the equator.
C. at about 30° north and south latitudes.***
D. at the north and south poles.
19. Why do winds curve? The Coriolis Effect makes the winds curve.
20. The Coriolis effect is caused by rotation of the earth
21. Name the 3 energy/heat transfers. Circle the one that is responsible for the moving bands of air around Earth.
Conduction – heat transfer by direct contact
***Convection – heat transfer of matter, warm rising and cool sinking
Radiation – heat transfer by electromagnetic waves, can travel through empty space as well as through particles
