Winds and Calm Regions - Review
1. The sun heats certain areas more directly than others, so the air is warmer and rises. This
creates an area of ____________ pressure.
2. Cool air contracts and gets heavier. This causes it to sink and create an area of __________
pressure.
3. Wind moves from areas of _________ pressure to areas of __________ pressure.
4. Therefore, differences in __________________ causes (generates) wind.
5. The Coriolis Effect is a result of the ____________________ of the Earth.
6. The Coriolis Effect influences the __________________ direction of the wind, but NOT the
speed of the wind.
7. The Coriolis Effect causes winds in the Northern Hemisphere to curve to the ____________.
(Remember that it is from the WIND’s orientation, not necessarily yours).
8. The Coriolis Effect causes winds in the Southern Hemisphere to curve to the ____________.
GLOBAL WINDS
9. Draw an arrow to show how the winds curve as they travel from the North Pole to 60°N
latitude.
10. Draw an arrow to show how the winds curve as they travel from the South Pole to 60°S
latitude.
11. These winds are called the _____________________________, because they come from
the polar region and they blow from the east.
12. Draw BLUE arrows in the picture to show the polar easterlies in both hemispheres. Label it.
13. The polar easterlies are associated with the ________________ cell.

14. Draw an arrow to show how the winds curve as they travel from 30°N to 60°N latitude.
15. Draw an arrow to show how the winds curve as they travel from 30°s to 60°S latitude.
16. These winds are called the _______________________, because they blow from the west.
17. Draw RED arrows in the picture to show the westerlies in both hemispheres (between 30°
and 60° latitude). Label it.
18. The westerlies are associated with the ____________________ cell.
19. Draw an arrow to show how the winds curve as they travel from 30°N to the equator.
20. Draw an arrow to show how the winds curve 30°S to the equator.
21. These winds are called the _______________________, because sailors could rely on the
steady winds for their trade route.
22. Draw GREEN arrows in the picture to show the trade winds in both hemispheres (between
the equator and 30° latitude). Label it.
23. The trade winds are associated with the ____________________ cell.

CALM REGIONS
24. The calm region that is located at the equator is called the ____________________. It is
named after being very calm and mellow. Label this region and highlight it with a different
color.
25. The ______________________________________ are the calm regions located at the 30°N
and S latitudes. It is named for the horses that were cast overboard when they starved to death
as the sailors were travelling. Label this region and highlight it with a different color.
