Outcome 7: Weather and Climate
1. Compare the differences between a land breeze and a sea breeze.
2. How do air masses affect weather?
3. Compare the differences between cold fronts and warm fronts.
4. Anemometer, barometer, sling psychrometer are all weather instruments. What do they
measure?
5. In which planetary wind belt do most storms move toward the northeast?
(1) 30° N to 60° N
(2) 0° to 30° N
(3) 0° to 30° S
(4) 30° S to 60° S
6. The cross section below represents prevailing winds moving over a coastal mountain range.
Letters A through D represent locations on Earth’s surface.
Which location will most likely have the least annual precipitation?
(1) A
(2) B
(3) C
(4) D
7. Explain how greenhouse gases cause global warming to occur.
-Greenhouse gases such as Carbon Dioxide (CO2) and Methane (NH4) trap infrared radiation that
is being emitted by the Earth and re-radiating it back to Earth’s surface.
8. Most of the air in the lower troposphere at the equatorial low-pressure belt is
(1) warm, moist, and rising
(2) warm, dry, and rising
(3) cool, moist, and sinking
(4) cool, dry, and sinking
Base your answer to question 9 on the map below, which shows a portion of New York State and
Canada. The arrows represent the direction of the wind blowing over Lake Ontario for several
days early one winter.
9. Explain why Oswego, New York, usually gets more snow than Toronto, Canada, when the
wind is blowing in the direction shown on the map.

The air travels over Lake Ontario toward Oswego, picking up moisture that results in
more snow.
10. The diagram shows a mercury barometer that is used to measure air
pressure. A decrease in the height of the mercury column usually means
the coming of a:
(1)
(2)
(3)
(4)
low-pressure system and stormy weather
low-pressure system and clear weather
high-pressure system and stormy weather
high-pressure system and clear weather
The incomplete flowchart below shows some of the changes that occur in warm air as it rises to
form a cloud.
11. Which statement should be placed in the empty box to accurately complete the flowchart?
(1)
(2)
(3)
(4)
The air warms as it expands.
The air cools until it reaches the dewpoint.
The air’s relative humidity decreases to zero.
The air enters the thermosphere.
Base your answer to the question on the weather map below, which shows the locations of a
high-pressure center (H) and a low-pressure center (L) over a portion of North America. The
isolines indicate surface air pressures.
12. The arrows on which map best show the pattern of surface winds around these two pressure
centers?
1.
3.
2.
4.
13. What is the usual surface wind pattern within a Northern Hemisphere low-pressure system?
(1)
(2)
(3)
(4)
clockwise and outward
clockwise and inward
counterclockwise and outward
counterclockwise and inward
14. Which front will most likely pass over location A during
the next two hours?
(1)
(2)
(3)
(4)
warm
stationary
occluded
cold
15. What is the dewpoint when the dry-bulb temperature is 8°C and the wet-bulb temperature is
2°C?
(1)
(2)
(3)
(4)
28°C
6°C
3°C
−9°C
Base your answer to question 16 on the weather map below. The map shows isobars and seven
weather station models. Four of the weather stations are identified by letters A, B, C, and D.
16. What was the probable
air pressure, in millibars, at
station D?
(1)
(2)
(3)
(4)
1015.0 mb
1017.0 mb
1021.0 mb
1036.0 mb
The weather map below shows isobars labeled in millibars. Points A, B, C, and D are locations
on Earth’s surface.
17. Which location was probably experiencing the highest wind speed?
(1)
(2)
(3)
(4)
A
B
C
D
Base your answer to question 18 and 19 on the weather station model below and on your
knowledge of Earth science. The model shows atmospheric conditions at Oswego, New York.
18. Convert the coded air pressure shown on the station model into the actual millibars of air
pressure.
999.5 mb
19. Explain how the data on the station model indicate a high relative humidity.
-When the temperature and the dewpoint temperature are the same or almost the same, it
means that the air cannot hold any more moisture and it will mean high humidity.
20. The California Ocean Current, which flows along the west coast of North America, is a
(1) cool current, flowing north
(2) cool current, flowing south
(3) warm current, flowing north
(4) warm current, flowing south
