Introduction and Coriolis Effect (page 561)
1. What causes wind? _________________________________________________________________________
2. Wind always flows from areas of ________ pressure to areas of _________ pressure.
3. What is the Coriolis effect and what causes it?
2. Global Winds (figure 2, page 562): Color and label the diagram below as follows:
a. Label each wind belt (NE and SE Trades, Westerlies, Polar Easterlies). Color the Trades, Westerlies, and
Easterlies different colors. (color lightly so your label can still be seen)
b. Draw a convection cell on the left side of the diagram showing the net flow of air on Earth.
c. Draw convection cells on the right side of the diagram showing the actual global circulation.
d. Identifty areas of low pressure and areas of high pressure. Color each belt of high pressure one color, and
each belt of low pressure another color
e. Label the horse latitudes and the doldrums

Land and Sea Breezes (page 564)
(2) Label the temperature and pressure conditions on the diagrams below that create the land and sea breezes.
Color the wind arrows blue for cool air and red for warm air.
(3) Explain why sea breezes occur during the day and land breezes occur during the night.
(4) Why are land and sea breezes named the way they are?
(5) Read about “Mountain and Valley Breezes” on page 564. Label each diagram either ‘Valley Breeze” or
“Mountain Breeze”. Explain why mountain and valley breezes form below the correct diagram.
