Karst

For an introductory college-level physical geology class: a review of how groundwater dissolves limestone and produces caverns, tunnels, and erosional remnant hills that collectively are known as karst topography. The video gives examples of karst landforms from around the world, and ends with a review of the chemical reactions that dissolve the mineral calcite and precipitate it later to form stalactites, stalagmites, and columns.
Content within is based on information available in any standard introductory college geology textbook, such as Essentials of Geology -- Tarbuck and Lutgens -- Pearson Publishing.
**This video comes near the end of the semester, after the Groundwater video, so there may be terms with which the audience is unfamiliar. For a full playlist, refer to the Geology playlist on the Earth Rocks! RUclips Channel.

Nice presentation...

[@stevekluth9060]

Easy mnemonic. Stalactite has a C for ceiling. Stalagmite has a G for ground. One of the best things I learned in grade school.

How are the stalactites formed in underwater caves?

[@EarthRocks]

They aren't. They can only form in caves that are above the water table. So if you see stalactites in caves that are fully underwater today, that means they were exposed and without water at some point in the past. :)
