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 key cave types?Karst, lava tubes, sea caves, talus caves
2. What is the paleoclimatic data source?Speleothems (stalactites, stalagmites) through isotopic and chemical analysis
3. What are the most common types of caves and how do they form?Karst caves form when acidic water dissolves limestone, creating tunnels underground. Lava tubes are made when hot lava flows and then cools, leaving a hollow channel. Sea caves are carved by waves and tides along coastlines. Talus caves form in piles of rock debris on unstable slopes.
4. How do scientists learn about past climates from caves?Speleothems, like stalactites and stalagmites, grow slowly and trap tiny chemical clues from water and air. By studying these clues, scientists can see how much rain fell and how warm or cold it was in the past.

Speleogenesis: The geological process by which caves are formed, primarily through dissolution.
Speleothem: A mineral formation that grows within a cave, such as a stalactite or stalagmite.
Allochthonous: Originating from or produced elsewhere; in caves, referring to organic matter entering from the surface.
