Limestone is the rock that is in Caves. When carbonate acid is reacted to the limestone in the caves, it will corrode forming strange caves landforms.
It helps form both - though the cave comes first! The CO2 solutuion is slightly acid - carbonic acid - and this dissolves the calcium carbonate that is limestone's main constituent.

A cave or sinkhole.
The "acid" form of CO2 and H2O is H2CO3, carbonic acid.
a long time. Acid rain and other erosion methods erode the rock to form a cave then an arch then a stack
Sulfuric acid and gasses erodes the limestone and produces gypsum crystals over thousands of years.
Precipitation of calcium carbonate in its crystalline form, calcite, from solution in weakly acid ground-water from the limestone above the cave.
As it starts to break down all of the rock it starts to create space therefor a cave or cavern can be made.

A hammer.
Acidic ground water (rain-water that has absorbed atmospheric carbon dioxide to form carbonic acid) dissolving the limestone as it flows through the joints & other discontinuities in the rock mass. As well as forming the cave passages, the calcite held in solution may precipate on exposure to the cave air as the solution emerges from a joint in the cave roof, to develop stalactites & stalagmites.
