Limestone Caves - how do they form (the chemistry of solution caves)

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...
