Example Questions
Example Question #1 : Describe The Motion Of Air Masses
The image above depicts the motion of two air masses in what kind of front?
a stationary front
a warm front
an occluded front
a cold front
a cold front
The answer is "a cold front."
A cold front moves faster than a warm air mass. The warm humid air is pushed up and results in a short period of heavy rain and possibly violent thunderstorms.
A warm front moves slower than a cold air mass. The warm raises steadily above the cooler air mass and causes gentle rain showers for longer periods of time.
An occluded front is a combination of two fronts that form when a cold front catches up and overtakes a warm front. The result is a mix of rain showers and thunderstorms.
A stationary front is the boundary between two air masses when neither is moving. Clear skies to partly cloudy skies may result, with occasional light rain.
Example Question #2 : Describe The Motion Of Air Masses

Example Question #3 : Describe The Motion Of Air Masses
A warm front moves slower than a cold air mass. What kind of weather is caused when warm air raises steadily above the cooler air mass?
gentle showers

thunderstorms
a mix of clear skies and rain showers

What type of front is occuring when warm humid air of a warm air mass is pushed up and results in a short period of heavy rain and possibly violent thunderstorms?
an occluded front
a stationary front
a warm front
a cold front

Example Question #6 : Describe The Motion Of Air Masses
What weather condition is most likely to be the result of two air masses with greatly different air pressures colliding?
snow
high winds
high humidity
gentle showers
high winds
The answer is "high winds" because the types of air masses were not defined and wind is caused by differences in air pressure.

Example Question #7 : Describe The Motion Of Air Masses
Which of the following best describes how air masses move across the United States?
The movement of air masses depends on the temperature of each state in the United States.
The jet stream moves air masses north and south across the United States.
The westerlies move air masses from west to east but sometimes get deflected by the jet stream.
The trade winds cause air to move from the Atlantic to the Pacific coasts.
The westerlies move air masses from west to east but sometimes get deflected by the jet stream.
The answer is "The westerlies move air masses from west to east but sometimes get deflected by the jet stream."
A cold front moves faster than a warm air mass. The warm humid air is pushed up and results in a short period of heavy rain and possibly violent thunderstorms.
A warm front moves slower than a cold air mass. The warm air rises steadily above the cooler air mass and causes gentle rain showers for longer periods of time.

Example Question #2 : Describe The Motion Of Air Masses
Which of the following is defined as "a relatively narrow band of strong wind in the upper levels of the atmosphere moving from west to east caused by Earth's rotation"?
The Easterlies
The Westerlies
Trade Winds

The Jet Stream
The answer is "The Jet Stream"

Example Question #9 : Describe The Motion Of Air Masses
Which of the following moves air masses from west to east, due to prevailing winds in the middle latitudes between 35 and 65 degrees latitude?
The Jet Stream
The Easterlies
Trade Winds
The Westerlies
The Westerlies
The answer is "The Westerlies."Prevailing Westerlies are the winds in the middle latitudes between 35 and 65 degrees latitude. They tend to blow from the high pressure area in the horse latitudes towards the poles. These prevailing winds blow from the west to the east steering extratropical cyclones in this general manner.
