How do stalactites, stalagmites, columns, drip curtains, and travertine terraces form? What will be an ideal response?
Stalactites are icicle-like structures that hang from the ceiling due to precipitation from dripping water.
Each drop leaves a thin layer of calcite over the previous layer, so the structure grows down from the
ceiling. Stalagmites grow upward from the floor from small drops that come off the stalactite. A
column forms when a stalagmite and stalactite meet. A drip curtain is created by water seeping from a
crack in the caves ceiling to form a vertical sheet of rock. Water flowing along the cave's floor can
produce travertine terraces.
