Quizplus · Accepted Answer

Land subsidence is not involved in cave formation in limestone. Mildly acidic groundwater dissolves the calcium carbonate in the limestone rock, creating openings and passageways. This combined with the dissolution of carbonate rocks creates the spaces that eventually form caves. A dropping water table can also contribute to cave formation by exposing the limestone to air, allowing for greater dissolution. However, land subsidence is not a necessary factor in cave formation.
