Stalagmites are made of calcium carbonate. When you at HCl, it liberates carbon dioxide and forms calcium chloride
You would go to a cave if you wanted to see a stalactite.
It's a stalactite that hangs from the ceiling.
water rich in dissolved carbonate drips from the ceiling of caves. As it drips, carbonate (CaCo3) precipitates out bit by bit, creating the stalactite.
yes,it occurs
I think I could be wrong, but is it because naturally acidic rain can cause limestone to dissolve, and this can make a cave?
(I came across this during revision and this completely confused me, I'm almost sure to fail! But this is just what I guessed via the text!)

You are right in describing what are called "karst" caves, i.e. those formed in limestone by slightly acidic water dissolving it, but other types of cave in non-limestone rocks exist, formed by other mechanisms.
No those are stalagmites. stalactites grow from calcite (or mineral) deposits from water dripping from cracks from the ceiling.
:) hope this helped
It is known - they are calcite deposits precipitated from soultion in ground-water that dissolved it from the limestone above the cave.
The real puzzle is the development of "helictites" - stalactites chemically and in principle, but growing into fantastic shapes like spaghetti, and no one theory fits them all!
