What formation is created when a stalactite and stalagmite meet?

When a stalactite, which hangs from the ceiling of a cave, and a stalagmite, which rises from the floor, meet, they form a structure known as a column. This formation occurs over a long period as mineral deposits accumulate from dripping water. The continuous deposit of minerals causes the stalactite and stalagmite to grow towards each other, eventually connecting them to create a single, solid column that is a striking feature within caves. This geological process showcases the dynamic and intricate nature of cave formations, highlighting how these natural structures evolve over time through mineral deposition.
