In caves dripping groundwater containing calcium bicarbonate can form stalactites and stalagmites . when the water is exposed to air some of the calcium bicarbonate turns calcium carbonate which gets?

deposited as mineral formations. As the water drips from the ceiling of the cave, it leaves behind calcium carbonate, which gradually builds up into stalactites hanging from the roof. Conversely, when the water drips onto the cave floor, it creates stalagmites that grow upward. Over time, these formations can grow significantly, creating striking underground landscapes.
