Air Pressure and Types of Precipitation

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 millibars or inches of mercury.

Front

How does air pressure change with altitude?

Back

Air pressure decreases as altitude increases. This is because there is less air above you as you go higher.

Front

What weather conditions are associated with high air pressure?

Back

High air pressure is usually 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, or stormy weather.

Front

What instrument is used to measure air pressure?

Back

Air pressure is measured with a barometer.

Front

What happens to air pressure when a storm is approaching?

Back

Air pressure typically drops when a storm is approaching, indicating a low pressure system.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What type of precipitation occurs when temperatures are below freezing?

Back

When temperatures are below freezing, precipitation can fall as snow or ice.

Front

What is the difference between rain and snow?

Back

Rain is liquid water droplets that fall when temperatures are above freezing, while snow is made of ice crystals that form when temperatures are below freezing.

Front

What is a thunderstorm?

Back

A thunderstorm is a rain-bearing cloud that produces lightning and thunder, often associated with heavy rain and strong winds.
