Air Pressure

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above us. It decreases as altitude increases.

Front

What happens when air pressure decreases?

Back

When air pressure decreases, it can lead to cloudy skies and precipitation, such as rain or snow.

Front

What type of weather is associated with high air pressure?

Back

High air pressure is usually associated with clear skies and dry weather.

Front

What type of weather is associated with low air pressure?

Back

Low air pressure is often associated with storms and precipitation.

Front

What instrument is used to measure air pressure?

Back

A barometer is used to measure air pressure.

Front

What does a falling barometer indicate?

Back

A falling barometer indicates that air pressure is decreasing, which may lead to stormy weather.

Front

What does a rising barometer indicate?

Back

A rising barometer indicates that air pressure is increasing, which may lead to clear and dry weather.

Front

How does air pressure affect wind?

Back

Air moves from areas of high pressure to areas of low pressure, creating wind.

Front

What is the relationship between temperature and air pressure?

Back

Warm air is lighter and rises, leading to lower air pressure, while cool air is denser and sinks, leading to higher air pressure.

Front

What is a high-pressure system?

Back

A high-pressure system is an area where the air pressure is higher than the surrounding areas, usually bringing clear skies.
