When too much erosion occurs in a cave the of the cave will collapse and create a sinkhole.
As it starts to break down all of the rock it starts to create space therefor a cave or cavern can be made.
The ground-water is a solution of calcium carbonate it has dissolved from the limestone above the cave. The mineral is subsequently precipitated as deposits of calcite in the cave: stalatcties & stalagmites, and flowstone on the floor and walls.

What is is the difference between renewable groundwater and nonrenewable groundwater?
Groundwater seeping through the limestone rock over thousands of years dissolved the rock, creating cracks and fissures. Eventually, these cracks formed larger passageways that became the cave system of Lascaux.

A cave or sinkhole.
Stalactites and Stalagmites.
A cave deposit formed by precipitation of calcium carbonate from groundwater entering an underground cavern which forms a hanging feature from the ceiling or wall of the cave.
A cave is a void (hole) in the ground. An aquifer is a region of water-permeable rock that holds groundwater; it may (or may not) contain caves.
