How does an air mass form?

When the air over a large region of Earth sits in one place for many days

When the air over a small region of Earth sits in one place for many days

When the air over a small region of Earth moves constantly

When the air over a large region of Earth moves constantly

What are the characteristics of an air mass?

Temperature and humidity are nearly the same in different locations at the same altitude

Temperature and humidity are different in different locations at different altitudes

Temperature and humidity are nearly the same in different locations at different altitudes

Temperature and humidity are different in different locations at the same altitude

How does the weather change with the arrival of a new air mass?

The temperature and humidity can increase or decrease

The temperature and humidity stay the same

The temperature and humidity increase

The temperature and humidity decrease

What is the difference between continental and maritime air masses?

Continental air masses form over land, while maritime air masses form over water

Continental air masses are cool, while maritime air masses are hot

Continental air masses form over water, while maritime air masses form over land

Continental air masses are moist, while maritime air masses are dry

How do the characteristics of a region affect the air mass it produces?

They determine the moisture and temperature of the air mass

They determine the altitude of the air mass

They determine the size of the air mass

What are the two words used to name an air mass category?

One for moisture, one for temperature

One for speed, one for direction

One for pressure, one for humidity

What is the impact of land and water on air mass formation?

Land causes air masses to become cooler and drier, while water causes air masses to become warmer and moister

Land and water have no impact on air mass formation

Land and water cause air masses to become the same temperature and moisture level

Land causes air masses to become warmer and moister, while water causes air masses to become cooler and drier

What is the relationship between the temperature change and the type of front?

The type of front determines the temperature change

The temperature change is always the same

The temperature change determines the type of front

What is a characteristic of a cold front?

Produces tall cumulonimbus clouds

Moves up and over a mass of denser and colder air

Brings many hours of steady rain or snow

What is a difference between cold fronts and warm fronts?

Warm fronts move gradually up and over a mass of denser and colder air

Warm fronts produce tall cumulonimbus clouds

Cold fronts move more slowly than warm fronts

Cold fronts bring many hours of steady rain or snow

What is a characteristic of a warm front?

Moves up and over a mass of denser and colder air

Brings many hours of steady rain or snow

Produces tall cumulonimbus clouds

Moves quickly and pushes warmer air upward

What is the process of how a warm front moves into an area?

Moves gradually up and over a mass of denser and colder air

Moves quickly and pushes warmer air upward

Stops moving and stays stationary

What is a characteristic of stationary fronts?

Air masses first meet or a front stops moving

Produces tall cumulonimbus clouds

Brings many hours of steady rain or snow

Moves up and over a mass of denser and colder air

What are the effects of cold fronts on weather?

Tall cumulonimbus clouds and precipitation

Many hours of steady rain or snow

Clear and cool air after storms

What are the effects of warm fronts on weather?

Many hours of steady rain or snow

Tall cumulonimbus clouds and precipitation

Clear and cool air after storms

What types of clouds are associated with cold fronts?

High cirrus clouds, then high stratus clouds, then lower and lower stratus clouds

What types of clouds are associated with warm fronts?

High cirrus clouds, then high stratus clouds, then lower and lower stratus clouds

How do stationary fronts occur?

When air masses first meet or when a cold or warm front stops moving

When a cold front moves into a warm front

When a warm front moves into a cold front

What is the location of the highest pressure in a region?

At the center of a high-pressure system

At the edge of a high-pressure system

At the center of a low-pressure system

At the edge of a low-pressure system

What is a low-pressure system?

A large weather system that surrounds a center of low pressure

A small weather system that surrounds a center of low pressure

A small weather system that surrounds a center of high pressure

A large weather system that surrounds a center of high pressure

How does a low-pressure system form?

Air moves around and inward toward the lowest pressure and then up to higher altitudes

Air moves outward toward the lowest pressure and then down to lower altitudes

Air moves around and inward toward the highest pressure and then up to higher altitudes

Air moves outward toward the highest pressure and then down to lower altitudes

Where can a low-pressure system develop?

Anywhere there is a center of low pressure

Anywhere there is a center of high pressure

What is the relationship between a low-pressure center and fronts?

They become parts of a whole weather system

They are separate weather systems

They are unrelated to each other
