What's the difference between a stalactite and stalagmite?

Stalactites and stalagmites are formed in caves by the deposition of calcium carbonate. Stlactites are the conical deposits that form at the roof of the cave and hang downward while stalagmites are those that form on the bottom of the cave and grow upward as water drips down from above.

To remember the difference between the two, think of stalactites as holding tight ("tite") to the ceiling of the cave.
