A. north to south
B. south to north
C. west to east
D. east to west
Which statement best describes the relationship between wind and air pressure?
Lower-pressure areas are associated with weaker winds.
Higher-pressure areas are associated with stronger winds.
Winds move from areas of low pressure to areas of high pressure.
Winds move from areas of high pressure to areas of low pressure.
Which type of cloud would be most likely to produce a thunderstorm?
nimbostratus
cumulonimbus
cirrostratus
altocumulus
Which factor is least associated with wind production?
precipitation
Coriolis effect
pressure differences
uneven atmospheric heating
Which weather event will most likely occur when a warm air mass moves over the ocean?

snowfall
rainfall
This map shows weather conditions in various locations in the United States. Several locations have been identified with numbers. At which location is a warm front currently approaching?
①
②

④
Air masses moving inland from oceans tends to hold more moisture than air moving over land. Which statement best describes how a high moisture content affects the climate in coastal areas as compared to inland areas?
There is less condensation in coastal areas.
There is more precipitation in coastal areas.
It prevents fog from occurring in coastal areas.
It prevents hurricanes from occurring in coastal areas.
How does convection affect weather?
Convection moves air and water rapidly in the atmosphere, creating high pressure.
Convection circulates the heat and pressure in the atmosphere, creating precipitation.
Convection changes the rate at which water flows in clouds, producing heavy rains.
Convection causes air to rise and fall, affecting temperature, wind, and windchill.
The direction of the wind curves to the right in the Northern Hemisphere, while it curves to the left in the Southern Hemisphere. What causes this?
plate tectonics
continental drift
the Coriolis effect
the pull of gravity
What is most likely to occur if the reading on a barometer is low and cumulonimbus clouds are present?
A storm or severe weather is most likely to occur.
Clear skies and calm weather will prevail.
Temperatures will rise significantly.
There will be no change in weather conditions.
Which statement best explains what occurs during convection?
Winds move from high to low pressure.
Warm air cools, causing a cold front to push through.
Warm air rises and cool air sinks, increasing the circulation of air.
Earth’s rotation on its axis causes winds to change speed and direction.
What is often responsible for the occurrence of fast-moving storms in the United States?
doldrums
jet stream
trade winds
polar easterlies
What will most likely occur if the barometric pressure begins dropping?
The skies will be fair.
Wind speed will increase.
Precipitation will increase.
The weather will remain the same.
This diagram shows weather in the United States. Which type of front is moving away from Chicago?
cold front
warm front
low pressure front
high pressure front
Rosie is facing the ocean at 2:00 pm and notices a strong breeze blowing through her hair. Which statement best explains this?
In which direction do weather systems usually move in the United States?
from east to west
from west to east
from north to south
from south to north
A cold front headed toward a town could cause severe weather because:
it can bring thunderstorms and heavy rain
it increases temperatures rapidly
it causes clear and sunny skies
it leads to calm and dry conditions
Which local winds are occurring when cool air is moving toward the ocean?
westerlies
sea breezes
global winds
land breezes
What results from the unequal heating of Earth’s surface?
cloud formation
ocean currents
water evaporation
wind patterns
Refer to the graph titled 'Barometric Pressure over a 7-Day Period.' When did a low-pressure system move through the area?
between day 1 and day 2
between day 2 and day 3
between day 4 and day 5
between day 6 and day 7
A weather map shows a blue line with triangles attached moving toward a city. Which is most likely going to happen in the city in the near future?
The temperature will fall.
Clouds will form
Precipitation will increase.
All of the above
Why does a warm air mass move over the top of a cold air mass when the two meet?
Warm and cold air have the same density.
Warm air is more dense than cold air.
Warm air is less dense than cold air.
Warm air carries more water vapor.
Which air mass would most likely produce a dry, cold frontal boundary?
maritime polar
continental polar
