Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the source region characteristics?Formation occurs over large, uniform areas allowing for thermodynamic equilibrium
2. What is the modification processes?Air masses change temperature and humidity as they traverse different underlying surfaces
3. How do air masses form?They form when air stays over the same area for days or weeks, warming or cooling and picking up moisture from the ground.
4. Why do we call some air masses "polar" or "tropical"?The name tells where they come from: polar means they come from cold high‑latitude places, tropical means they come from warm low‑latitude places.

Aerological Stagnation: A period of calm atmospheric conditions allowing air to develop uniform properties.
Synoptic Scale: Weather phenomena that occur over large geographical areas and time periods (hundreds to thousands of kilometers).
Atmospheric Stability: The tendency of the atmosphere to resist or promote vertical air movement, influencing cloud development.
