DictionarystalagmiteCave-floor mineral deposit
noun

stalagmite

stuh-LAG-myte/stəˈlæɡmaɪt/

A mineral deposit that grows upward from a cave floor.

A stalagmite rises from the cave floor beneath dripping water.

A single prominent mineral stalagmite rises from a small patch of cave floor, with a water droplet falling toward its rounded tip.
Etymology

The Latin name draws on Greek stalagmos, “dripping,” or stalagma, “a drop.” It names the cave-floor formation for the dripping water that builds it, rather than for its upward-pointing shape.

In context

SciShow Kids4:18
If the water dries up before it drips to the ground, it forms a stalactite… and if it drips onto the ground, a stalagmite grows up!
