The reaction of carbonic acid in rain and groundwater with the carbonate rock.
limestone and dolomite bedrock, which are easily dissolved by water, forming caves and caverns in the Valley and Ridge province of Virginia. The acidic groundwater slowly dissolves the carbonate rocks over time, creating underground cavities and networks of caves.
Most carbonate rocks, such as limestone and dolomite, are formed through the accumulation and cementation of calcareous marine organisms like corals, mollusks, and algae. These organisms produce calcium carbonate shells and skeletons that build up over time to create carbonate rock formations. Other processes, like precipitation from seawater or chemical reactions in caves, can also contribute to the formation of carbonate rocks.
Caves caused by volcanic activity are made of basalt Caves caused by dissolution due to groundwater are formed in limestone or sometimes marble. Caves also form in glacial ice due to melting. (Glacial ice can technically be considered rock.)
Stalactites and stalagmites are formed from calcium carbonate minerals, making them part of sedimentary rocks. They are created in caves from mineral-rich water dripping from the ceiling (stalactites) or depositing on the floor (stalagmites) over time.
Sinkholes and caverns are formed from carbolic acid. This carbolic acid dissolves rock which creates the spaces that form the sinkholes and caverns. The carbolic acid is created when carbon dioxide dissolves in water.
Caves, caverns, and sinkholes are typically formed by the dissolution of soluble rocks such as limestone, dolomite, or gypsum by water. Over time, water erodes and dissolves the rock, creating underground cavities and passages. Eventually, these cavities can collapse or become exposed at the surface, forming caves, caverns, and sinkholes.
Caverns are typically formed through a process known as karstification, where groundwater dissolves soluble rocks like limestone and carbonate rocks over time. This dissolution, along with other factors such as erosion and tectonic forces, can create underground cavities and passageways that eventually turn into caverns.

Most caves are in limestone or dolomite rocks. Some (e.g. Carlsbad Caverns) are in gypsum rocks. But caves can also exist in lava deposits (e.g. lava tube caves), marble rocks (i.e. metamorphosed limestone), and many other types of rocks at lower rates, depending on various variables.

Caves
More accurately I think you mean "What type of rocks hold caves?" The majority of caves are in Limestone; some in its metamorphic edition, Marble. These, "karst" caves, often also hold calcite deposits (stalactites etc) formed by precipitation of the calcium carbonate dissolved from the rock above the cave by the water oozing through its joints. There are also lava tubes in basalt lava, formed by molten rock flowing from below a solidified crust. Sea-caves and mass-movement fissures can occur in most competant rocks.
No, most caverns form below the water table. Caverns are typically formed by the dissolution of underground limestone or other soluble rocks by water, and this process usually occurs below the water table where the rocks are saturated with water.
Tufa and calcium carbonate can be found in mammoth caves ,Kentucky.
Limestone, chalk, and marble are examples of rocks that are natural sources of calcium carbonate. These rocks are formed from the accumulation of calcium carbonate minerals over time, which can be used for various purposes including in construction, agriculture, and industry.
