• cold front

• stationary front

• warm front

Why does air pressure decrease from the troposphere to the exosphere?

• because there are more air molecules as altitude increases

• because there are fewer air molecules as altitude increases

• because there are lower temperatures as altitude increases

• because there are higher temperatures as altitude increases

Which type of air mass is the most responsible for the cold weather that travels from Canada to North Carolina during the winter?

• maritime tropical

• maritime polar

• continental tropical

• continental polar

7.E.1.3

Which statement describes what is happening in the picture?

• As a cold front moves, the colder, less dense air moves below the warmer air, and this causes storms.

• As a cold front moves, the colder, less dense air moves above the warmer air, and this causes storms.

• As a cold front moves, the colder, more dense air moves above the warmer air, and this causes storms.

• As a cold front moves, the colder, more dense air moves below the warmer air, and this causes storms.

Which statement best describes the formation of a warm front?

• As a cold front moves, the colder, more dense air moves below the warmer air, and this causes storms.

• Cold air moves up over warmer air.

• The temperature in a warm air mass increases.

• Warm air glides over colder air.

Use the image above to determine which city is most likely having severe weather?

• Asheville

• Charlotte

• Jacksonville

• Raleigh

Why is a low-pressure system generally associated with cloudy and rainy weather?

• As cool air rises, it becomes colder, generating freezing rain.

• As cool air rises, it warms in the atmosphere, generating severe weather.

• As warm air rises, it cools in the atmosphere, creating condensation.

• As warm air rises, it gets warmer in the atmosphere, creating precipitation.

7.E.1.3

Which choice describes cool air masses?

• They rise when lifted up by more dense warm air masses.

• They mix easily with warm air masses.

• They are less dense and flow over warm air masses

• They are more dense and flow under warm air masses
