Air Pressure and Fronts

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a surface. It decreases with altitude.

Front

What is a cold front?

Back

A cold front is a boundary where a cold air mass pushes into a warm air mass, often resulting in thunderstorms and heavy rain.

Front

What is a warm front?

Back

A warm front is a boundary where warm air rises over a cold air mass, leading to gradual weather changes and light rain.

Front

What is an occluded front?

Back

An occluded front occurs when a cold front overtakes a warm front, causing a mix of rain showers and thunderstorms.

Front

What is a stationary front?

Back

A stationary front is a boundary between air masses that are not moving, often resulting in prolonged cloudy and rainy weather.

Front

What type of weather is associated with a low pressure system?

Back

A low pressure system is typically associated with cloudy, stormy weather and precipitation.

Front

What type of weather is associated with a high pressure system?

Back

A high pressure system is usually associated with clear skies and calm weather.

Front

How does altitude affect air pressure?

Back

As altitude increases, air pressure decreases because there is less air above the surface.

Front

What symbol represents a cold front on a weather map?

Back

A cold front is represented by a blue line with triangles pointing in the direction of the front.

Front

What symbol represents a warm front on a weather map?

Back

A warm front is represented by a red line with semicircles pointing in the direction of the front.
