What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a surface. It is measured using a barometer.

Front

What does a barometer measure?

Back

A barometer measures air pressure. It helps predict weather changes.

Front

What does high air pressure indicate about the weather?

Back

High air pressure usually indicates clear and calm weather.

Front

What does low air pressure indicate about the weather?

Back

Low air pressure often indicates cloudy, rainy, or stormy weather.

Front

What is a hygrometer used for?

Back

A hygrometer measures humidity, or the amount of moisture in the air.

Front

What does a thermometer measure?

Back

A thermometer measures temperature, indicating how hot or cold something is.

Front

What is the relationship between temperature and air pressure?

Back

Generally, as temperature increases, air pressure decreases, and vice versa.

Front

What weather conditions are associated with a hygrometer reading of 35% humidity?

Back

A hygrometer reading of 35% humidity suggests dry air, which may indicate clear weather.

Front

What does a barometric reading of 29.1 inches of Hg suggest?

Back

A barometric reading of 29.1 inches of Hg suggests low air pressure, which may lead to rain.

Front

What is the significance of a barometric reading of 30.6 inches of Hg?

Back

A reading of 30.6 inches of Hg indicates high air pressure, often associated with clear skies.
