A reaction of carbonic acid released into groundwater; this alos leads to the formation of stalagtites and stalagmites.

It is a combination of the two. In the early stages of formation the carbonic acid reaction does most of the work. At a later stage when there is enough space for water to flow rapidly scouring starts to take effect.

Carbonic acid. Carbonates are very soluble in acid. The greater the groundwater flux, the more carbonate will be dissolved, so fast flowing water probably wouldn't hurt either.

the abrasive action of groundwater peculating through line stone forms caves and caverns.
