In this episode, I talk about solution  (Limestone/marble) caves and how they form.  What is the chemistry behind their formation and their cave formations like stalactites and stalagmites?In fact, I mention the chemical equation that drives this reaction...click here to see it.Caves are fascinating places, and I hope this makes it easier for you to understand how solution caves form.If you want a fun activity, have a go at constructing this 3D paper cave.  Just print out, cut, and glue.Interested in joining us on a trip?  Check out our field adventures here. Support the show (https://www.buymeacoffee.com/Geoetc)
