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 location?Appalachian Mountains, West Virginia, United States
2. What is the primary driving force?Differential air pressure caused by external temperature and barometric pressure fluctuations
3. What does it mean that the Breathing Cave 'breathes'?The cave opens and closes its air like a breathing lung. When outside air pressure drops, the cooler air inside leaves the cave. When outside pressure rises, warmer air rushes in.
4. How does the cave know when to let air in or out?The cave has many entrances and passages that feel changes in outside pressure and temperature. When the outside gets warmer and the air expands, the cave pushes its cooler air out. When it cools, the denser outside air pushes into the cave.

Karst Topography: A landscape formed from the dissolution of soluble rocks like limestone, characterized by caves and sinkholes.
Barometric Pressure: The atmospheric pressure measured by a barometer, indicating changes in weather patterns.
Troglobite: An animal species that lives exclusively in caves and is unable to survive outside.
