U3M3L3 Inspire Science: Weather Patterns

Front

What are air masses?

Back

Large bodies of air that have uniform temperature, humidity, and pressure.

Front

How do air masses move?

Back

Air masses generally move from areas of high pressure to areas of low pressure.

Front

What happens when two air masses meet?

Back

They can create weather fronts, which may lead to changes in weather, such as storms.

Front

What is a high pressure system?

Back

A weather system characterized by sinking air, leading to clear skies and stable weather.

Front

What is a low pressure system?

Back

A weather system characterized by rising air, which can lead to cloud formation and precipitation.

Front

What is a cold front?

Back

A boundary where a cold air mass pushes into a warmer air mass, often causing storms.

Front

What is a warm front?

Back

A boundary where a warm air mass slides over a cold air mass, usually bringing gentle rain.

Front

What is the relationship between altitude and air pressure?

Back

As altitude increases, air pressure decreases.

Front

What are the signs of a tornado forming?

Back

Strong gusty winds, large differences in temperature and humidity, and a rotating cloud base.

Front

What is a frontal boundary?

Back

The area where two different air masses meet, which can lead to various weather phenomena.
