Air. A cavern is a void. :-)
Most caves are in limestone and formed by the rock's calcium carbonate (its main constituent) being dissolved away by rainwater acidified by absorbed by atmospheric carbon-dioxide.

Underground caverns are characterized by formations made of minerals such as stalactites, stalagmites, and columns. These structures are created by the slow deposition of minerals carried by water dripping or flowing through the cave.
Carlsbad Caverns is primarily formed by dissolution, a type of chemical weathering, of the limestone bedrock by acidic groundwater. This process creates the spectacular caves and caverns found in the area.
Caverns most commonly form in limestone bedrock, which is made of calcite minerals that can be dissolved by slightly acidic groundwater over time. This process creates underground cavities and passageways that can grow into large cavern systems.
Caverns are formed through a process of chemical weathering and erosion of soluble rocks, such as limestone, by percolating water. Gradual dissolution of the rock over time creates underground voids that eventually expand to form caverns. Additional factors like tectonic activity and the presence of natural faults can also contribute to cavern formation.

Howe Caverns is a cave located in New York, near Albany. It is thought to be at least a million years old and is made of limestone.

Caverns made of salt are suitable for burying toxic waste because salt has low permeability, which means it prevents the movement of liquids and gases. Additionally, salt caverns are stable and can seal themselves over time due to salt creep. Finally, salt caverns are generally located deep underground, minimizing the risk of environmental contamination.
Carlsbad Caverns.
Caverns can be under water and underground.
Carlsbad Caverns is located in New Mexico.
