10) The annual temperature range at most latitudes in the Southern Hemisphere is much smaller
than that in the Northern Hemisphere. The reason for this is that ________.
A) Earth is closest to the Sun during the Southern Hemisphere summer
B) rainfall and cloudiness are greater in the Southern Hemisphere
C) there is a greater percentage of water surface in the Southern Hemisphere
D) a greater proportion of the land surface is mountainous in the Southern Hemisphere
Answer: C
11) Examine the figure. What exact day of the year is depicted?
Explain.
Answer: The Northern Hemisphere's summer solstice is
depicted, since the circle of illumination intersects the Arctic
Circle, the southernmost latitude that experiences complete
sunlight for at least one day per year. The date is therefore June
21-22.

3) Examine the figure. This flask contains 1 kilogram of dry air mixed with
20 grams of water vapor. It is at 25°C temperature. What would happen if its
temperature was increased to 35°C?
A) The relative humidity would decrease, triggering evaporation from the
pool of liquid water at the bottom of the flask.
B) The relative humidity would decrease, triggering condensation, and raising
the level of the pool of liquid water at the bottom of the flask.
C) The relative humidity would increase, triggering condensation, and raising
the level of the pool of liquid water at the bottom of the flask.

C) when heat is neither added nor subtracted
D) when water vapor is added
Answer: C

6) A fire extinguisher containing compressed CO2 is used to put out a fire. In spite of being close
to the flames, the firefighter notices a white layer of "frost" forming on the exterior of the fire
extinguisher can. What's going on?
A) The gas in the extinguisher is expanding when released, cooling adiabatically.
B) The gas in the extinguisher is cooling under higher pressure.
C) The exterior temperature must be dropping.
D) The fire is pulling heat from the surrounding air.
Answer: A
7) Examine the figure. Which process is
illustrated?
A) orographic lifting
B) frontal wedging
C) adiabatic cooling
D) convergence
Answer: B

hurricane (tropical cyclone)?
A) A
B) B
C) C
D) D
Answer: D
2) Because unequal heating of Earth's surface generates these pressure differences,
________ is/are the ultimate energy source for most wind.
A) caves
B) hot springs
C) solar radiation
D) the greenhouse effect
Answer: C
3) Which of the four lettered locations on the map would have the highest pressure
gradient (and thus, the highest potential for winds)?
A) A

4) You are getting ready to go for a hike on a summer day. You check the barograph and
discover that the pressure tendency has been rising for several hours. Based on this information,
what gear should you be sure to pack for your hike?
A) snowshoes

known as the ________.
A) Hadley cell
B) subtropical high
C) trade winds
D) polar front
Answer: B
6) In Eurasia, the land becomes cold in the winter and develops a seasonal high-pressure system
from which surface flow is directed off the land. In the summer, in contrast, the opposite occurs:
The landmasses are heated and develop a low-pressure cell, which permits air to flow onto the
land. This "switch" in directions of airflow into or off of the continent gives rise to ________.
A) the monsoon
B) cyclones
C) the polar high
D) easterlies and westerlies
Answer: A
7) Which of these factors influence the magnitude of the Coriolis force?

11) Examine the map showing air pressure in
millibars. Compare and contrast what sorts of
weather situations would you expect at sites "B"
and "D" on the map.
Answer: Site D is a center of low pressure,
which means it's at the center of a midlatitude
cyclone. Surrounding this site will be bands of
clouds and wind that are flowing in toward
Maine, spiraling in a counter-clockwise direction
(because it is in the northern hemisphere). The
close spacing of the isobars suggests high winds,
too. All that air rising will likely be accompanied by precipitation. In contrast, site B, near New
Orleans, is a center of high pressure. This means descending air, relatively clear skies, and no
precipitation. It is likely surrounded by moderate winds spiraling outwards in a clockwise
divergent pattern.
