Answer Details
The downward-growing pinnacles that hang from the roofs of caves in limestone regions are called stalactites. Stalactites are formed by the slow dripping of water that contains dissolved calcium carbonate. As the water drips, it leaves behind small amounts of calcium carbonate, which gradually build up over time to form a cone-shaped structure that hangs from the ceiling of the cave. Stalactites can take many years to form and can grow to be several meters long, adding to the natural beauty and wonder of limestone caves.
