1. The instrument shown is used to
measure what?
4. Where does most of the energy of
the Earth’s winds come from?
A
B
C
D
A
B
C
D
wind direction
wind speed
air pressure
relative humidity
the Earth’s rotational energy
unequal air pressures caused by
variations in the heating of air
masses by the Sun
unequal concentrations of oxygen
and carbon dioxide which cause the
air to move to even them out
movement of air to equalize
variations in pressure caused by
varying concentrations of water
vapor.
Use the diagram of a hurricane to
answer the next three questions.
2. In North America, most weather
moves in which direction?
A
B
C
D
from West to East
from East to West
from North to South
from South to North
3. Near the coast, most local winds
blow from the ocean to the land
during the day (sea breeze). At
night, the winds blow from the
land to the ocean (land breeze).
Why does this happen?
A
B
C
D
The jet stream that blows from the
West to the East is absent during
the night
The moisture content of land and
water air is unequal.
The unequal cooling of land and
water.
The ocean currents which drive the
winds change from day to night.
5. If the hurricane’s eye were over
your house, how far would you
have to travel to be out of
danger?
A
B
C
D
200 km
1000 km
500 km
700 km

6. In the above diagram, inflowing
air originates from what farthest
distance?
A
B
C
D
500 km
1000 km
250 km
750 km
7. Cumulus clouds reach an altitude
of about:
A
B
C
D
10 km.
2.5 km.
5 km.
15 km.
C As the sun heats the cold air, it
becomes warm. It then mixes with
the warm air at high altitudes. This
mixture drives out the moisture,
causing rain.
D The warm air rises over the cold air
mass; as it does it is cooled. Cool air
can hold less moisture then warm
air, so the water vapor condenses,
forming rain.
Use the picture of air masses below
to answer the next two questions.
8. The diagram below shows the
boundary between a cold air
mass and a warm, moist air mass.
How does the interaction of the
cold air and the warm air often
cause rain at the boundary?
A The cold air carries more water
vapor than the warm air, so rain is
formed
B The boundary between the cold and
warm air masses is unstable. The
water present in both the air masses
precipitates because of the swirling
air currents.
9. Using the above map, identify the
two air masses that influence
Virginia the most.
A
B
C
D
cool, moist and warm, moist
cold, dry and warm, moist
hot, dry and warm, moist
cold, dry and hot, dry
10. Which topographic feature in
Virginia affects the air masses
moving across the state?
A
B
C
D
Appalachian Plateau
Blue Ridge Mountains
Fall Line
coastal plain
