FLASHCARD QUESTION
Front
Air Mass Noun
[air mas]
Back
Air Mass
A huge body of air that has similar temperature, humidity, and air pressure throughout its extent.
Example: This map shows different types of air masses. Blue polar masses are cold, and red tropical masses are warm. They form over land (continental) or water (maritime).

FLASHCARD QUESTION
Front
Front Noun
[frunt]
Back
Front
The boundary where two different air masses meet, which often results in significant changes in the weather.
Example: This diagram shows a cold front, where a dense cold air mass plows under a lighter warm air mass, forcing it to rise, cool, and form clouds and rain.

FLASHCARD QUESTION
Front
Continental Adjective
[kon-tuh-nen-tl]
Back
Continental
Describes a dry air mass that forms over a large land area and carries very little moisture.
Example: This diagram shows a large air mass forming over land (a continent), which is the defining characteristic of a continental air mass.

FLASHCARD QUESTION
Front
Maritime Adjective
[mar-i-tahym]
Back
Maritime
Describes a moist air mass that forms over a large body of water and carries significant moisture.
Example: This diagram shows that the air over a large body of water is cooler and contains more moisture (clouds, fog) than the air over land.

FLASHCARD QUESTION
Front
Tropical Adjective
[trop-i-kuhl]
Back
Tropical
Describes a warm air mass that forms in low-latitude regions near the equator, bringing warm air.
Example: This map shows the Tropics, the warm region around the Earth's equator where tropical air masses form before moving to other areas.

FLASHCARD QUESTION
Front
Polar Adjective
[poh-ler]
Back
Polar
Describes a cold air mass that forms in high-latitude regions near the poles, bringing cool air.
Example: This diagram shows a maritime Polar (mP) air mass moving from the ocean over mountains, cooling and releasing rain, then becoming dry on the other side.

FLASHCARD QUESTION
Front
Source Region Noun
[sors ree-juhn]
Back
Source Region
The geographical area over which an air mass develops and acquires its characteristic properties of temperature and humidity.
Example: This image shows the different source regions of air masses, helping students understand where different air types originate.
