(1) North
(2) South
(3) East
(4) West
11. _____ The fronts shown on a weather map are best described as
(1) boundaries between different air masses
(3) areas experiencing clear skies with light winds
(2) boundaries between different wind belts
(4) areas experiencing extremely warm air temperatures
The map below shows an air mass that formed over the Gulf of Mexico at location A.
12. _____Once air mass A reaches location B, the weather conditions at location B will most likely become
(1) warmer and drier (3) colder and more humid
(2) warmer and more humid (4) colder and drier
13. _____Which temperature and moisture conditions describe an air mass that originates over the Northwest US near
the border of Canada?
(1) warm and dry
(3) cool and dry
(2) warm and humid
(4) cool and humid
Use the map below and your knowledge of science to answer questions 14 and 15. The weather map below shows the
locations of a high-pressure center (H) and a low-pressure center (L), air masses cP and mT, and city A.
14. Explain why city A has clear sky conditions. [1] ___________________________________
15. In what direction is the warm front likely to move? [1] _____________________________
16. _____Which statement best explains why the Sun and the Moon appear to be about the same size in the sky?
1. The Sun and the Moon have the same diameter.
2. The Moon is larger in diameter and is farther from Earth as the Sun.
3. The Moon is smaller in diameter and is closer from Earth as the Sun.
4. The Sun and the Moon are the same distance from the Earth.
The diagram below shows Earth as seen from space. Letters A through D are locations on Earth’s surface.

experience the greatest number of daylight hours?
1. A
2. C
3. B
4. D
18. _____ The Sun appears to move across the sky during the day. The best explanation for this apparent motion is that
Earth is

(3) much smaller than the Sun
(2) revolving around the Sun
(4) tilted on its axis
