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, cut, and glue.
