Slide 38
What is a barometer?
Slide 39
This is where are pressure would be the lowest. A. at sea level B. on top of Mt. Everest C. at the bottom of the Grand Canyon D. on top of a skyscraper
Slide 40
What is B. on top of Mt. Everest?
Slide 41
Air at sea level is denser than air at high altitudes because A. the air molecules are pushed farther apart at sea level B. the air molecules are pushed closer together at sea level C. high altitudes cause air molecules to move closer together D. low altitudes cause air molecules to move farther apart
Slide 42
What is B. the air molecules are pushed closer together at sea level?
Slide 43
This causes wind to blow.
Slide 44
What is air pressure varies from place to place?
Slide 45
Wind moves horizontally from areas of what to what.
Slide 46
What is from areas of high pressure to areas of low pressure?
Slide 47
Earth rotates. How does this motion affect global winds? A. it causes the winds to curve B. it causes the winds to blow C. it causes the winds to move straight from the equator to the poles D. it causes the winds to move straight from the poles to the equator
Slide 48
What is A. it causes the winds to curve?
Slide 49
These are three types of wind belts in the Northern Hemisphere.
Slide 50
What is trade winds, horse latitudes, and westerlies?
Slide 51
What causes trade winds to blow?
Slide 52
Trade winds move from high to low pressure areas. They move from the horse latitudes (high pressure) to the doldrums (low pressure). So they blow from the east.
