Here's why:
* Water Flow: Flowstones form where water consistently flows along the cave walls. This flow can be slow and steady, or it can be more turbulent.
* Calcite Deposition: As the water moves, it carries dissolved minerals, primarily calcium carbonate (calcite). When the water evaporates or changes conditions, the calcite precipitates out and attaches to the cave wall.
* Formation: Over time, the deposition of calcite builds up, creating the characteristic smooth, wavy, and often layered appearance of a flowstone.
Flowstones come in various forms, such as:
* Curtains: These are thin, sheet-like formations that hang down from the cave ceiling.
* Draperies: Similar to curtains, but with more pronounced folds and ridges.
* Rimstone Pools: Flowstones that form a dam across a small channel of water, creating a pool.
* Gours: A series of small, stepped pools formed by flowstone.
