Front

How does air pressure change with altitude?

Back

Air pressure decreases as altitude increases.

Front

What weather conditions are associated with high air pressure?

Back

High air pressure is typically associated with clear and sunny weather.

Front

What weather conditions are associated with low air pressure?

Back

Low air pressure is often associated with cloudy, rainy, and stormy weather.

Front

What happens to air pressure during a storm?

Back

Air pressure usually drops significantly before and during a storm.

Front

What does a rapid drop in air pressure indicate?

Back

A rapid drop in air pressure often indicates that a storm is approaching.

Front

What is the relationship between air pressure and wind?

Back

Wind is caused by differences in air pressure; air moves from high to low pressure.

Front

What is the standard unit of measurement for air pressure?

Back

The standard unit of measurement for air pressure is millibars (mb) or inches of mercury (inHg).

Front

How can you use a barometer to predict weather changes?

Back

By observing changes in air pressure readings, you can predict upcoming weather changes.

What does a steady air pressure reading indicate?

Back

A steady air pressure reading usually indicates stable weather conditions.
