Caves
sometimes have icicle-like stone formations hanging from the roof or going up
from the cave floor. They are formed, sometimes over thousands of years by
water saturated with calcium carbonate dripping from the cave.
If
these formations are hanging down from the roof they are called STALACTITES. If
they are growing from the floor they are called STALAGMITES.
Stalactites
and stalagmites sometimes meet to form columns.
