Air Pressure

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a surface. It is measured in units like pascals (Pa) or millibars (mb).

Front

What happens to air pressure as altitude increases?

Back

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

Front

What type of weather is typically associated with low air pressure?

Back

Low air pressure is usually associated with cloudy weather and precipitation.

Front

What type of weather is typically associated with high air pressure?

Back

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

Front

How does air pressure affect wind?

Back

Wind is created by differences in air pressure. Air moves from areas of high pressure to areas of low 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, often leading to clear and calm weather.

Front

What is a low-pressure system?

Back

A low-pressure system is an area where the air pressure is lower than the surrounding areas, often leading to cloudy and rainy weather.

Front

What does increasing air pressure indicate about the weather?

Back

Increasing air pressure typically indicates that the weather will become clearer and drier.

Front

What does decreasing air pressure indicate about the weather?

Back

Decreasing air pressure typically indicates that the weather may become cloudier and wetter.

Front

What is the relationship between air pressure and temperature?

Back

Generally, warm air is less dense and rises, leading to lower air pressure, while cool air is denser and sinks, leading to higher air pressure.
