Over time it dissolves limestone or gypsum, so most caves are in those rocks, of which limestone is by far the more widespread.
Yes. Carbonic acid is one of the main factors in the formation of limestone caves.
Primarily in their mode of formation: dissolution of limestone by water acidified by atmospheric CO2 (forming carbonic acid).

Carbonic Acid .
Rain water + atmospheric CO2 gives Carbonic Acid - very weak but over time able to dissolve limestone.
Yes, caves are formed when carbonic acid, which is created by the reaction of water with carbon dioxide, dissolves underground limestone. Over time, the dissolved limestone is carried away by water, creating large openings and chambers that we call caves.
The chemical equation for Carbonic Acid is H2CO3.

Carbonic acid dissolves limestone by turning the mostly insoluble calcium carbonate into soluble calcium bicarbonate. The dissolution hollows out areas the the rock, creating caves. When one of these caves collapses a sinkhole will form above.
The reaction of carbonic acid in rain and groundwater with the carbonate rock.
