Air Masses and Fronts

Front

What type of weather front occurs when a warm air mass overrides/replaces a cold air mass?

Back

Warm Front

Answer explanation

A warm front occurs when a warm air mass overrides a cold air mass, leading to gradual temperature increases and often resulting in cloud formation and precipitation. Thus, the correct answer is Warm Front.

Front

Number 3 is the symbol for a ____________ front?

Back

Stationary Front

Answer explanation

Number 3 represents a stationary front, which is characterized by little to no movement of the air masses. This is distinct from cold, warm, and occluded fronts, which have specific symbols and indicate different weather patterns.

Front

Number 1 is the symbol for a ____________ type of front.

Back

Cold Front

Answer explanation

Number 1 represents a Cold Front, which occurs when a colder air mass pushes into a warmer air mass, causing the warm air to rise. This is distinct from other front types like warm or stationary fronts.

Front

When a warm air mass and a cold air mass meet, but there is not enough force (energy) to lift the warm air mass over the colder air mass-often brings days of cloudy wet weather.

Back

stationary front

Answer explanation

A stationary front occurs when warm and cold air masses meet but lack the energy to move, resulting in prolonged cloudy and wet weather. This matches the description given in the question.

Front

The boundary between two air masses is called a/an -

Back

front

Answer explanation

The boundary between two air masses is known as a 'front'. This term is used in meteorology to describe the transition zone where different air masses meet, leading to various weather conditions.

Front

When a cold air mass moves into a warm air mass and pushes the warm air mass away from the Earth's surface, the weather will get colder and we could have severe weather as a result of this type of front.

Back

cold front

Answer explanation

A cold front occurs when a cold air mass pushes into a warm air mass, causing the warm air to rise. This leads to colder temperatures and can result in severe weather, making 'cold front' the correct answer.

Front

When a warm air mass gently slides on top of a cold air mass, and you have drizzly rain and then warmer weather, what type of front is it?

Back

warm front

Answer explanation

A warm front occurs when a warm air mass slides over a cold air mass, leading to gradual lifting and resulting in drizzly rain followed by warmer weather. This matches the scenario described, confirming the correct answer is a warm front.

Front

A/An ____ is a large body of air similar temperature, moisture content, and pressure.

Back

air mass

Answer explanation

An air mass is defined as a large body of air that has uniform temperature, moisture content, and pressure. This distinguishes it from other options like fronts, clouds, and tornadoes, which do not fit this definition.

Front

What type of cloud is made of ice crystals and forms at high altitudes in the Earth's atmosphere?

Back

Cirrus

Answer explanation

Cirrus clouds are high-altitude clouds composed of ice crystals, typically forming above 20,000 feet. They appear wispy and are often seen in fair weather, distinguishing them from cumulus and stratus clouds.

Front

Which of the following would be an area that would most likely lead to the development of a warm (tropical) air mass?
The North pole,
The South pole,
The Equator

Back

The Equator

Answer explanation

The Equator is the region where warm, tropical air masses develop due to consistent solar heating. In contrast, the North and South poles are cold regions, making them unlikely to produce warm air masses.
