Science definitions for stalactites

stalactite

[ stə-lăktīt′ ]

A cylindrical or conical mineral deposit projecting downward from the roof of a cave or cavern, formed by the dripping of water saturated with minerals. Stalactites form gradually as the minerals precipitate out of the saturated water. They usually consist of calcite but can also consist of other minerals. Compare stalagmite.

Culture definitions for stalactites

stalactites

[ (stuh-lak-teyets) ]

Rock structures formed on the ceilings of caves as water drips down, leaving behind minerals before it falls. (Compare stalagmites.)

Note

Stalactites grow very slowly.

Note

One easy way to distinguish stalactites from stalagmites is to recall that stalactites “hold tight” to the ceiling of a cave. Stalagmites “might reach the ceiling” of the cave and form a column.
