Most caves - of any size - are in limestone, and those are all formed primarily by dissoultion of the rock by weakly acidic ground-water penetrating the joints, bedding-planes, faults and other permeabl discontinuities within the rock mass.

Large caves are called caverns. Caverns are characterized by their size and often contain unique geological formations such as stalactites and stalagmites. They are formed over millions of years through various geological processes.
Yes, Carlsbad Caverns National Park in New Mexico features a large underground limestone cave system. The main attraction is the Big Room, which is one of the largest cave chambers in North America.
A cavern is a large cave. Generally a cave is considered to be a cavern if it is large and extends a long way underground. Caverns often have other geological features within them such as stalactites or stalagmites. The exploration of caves and caverns is known as speleology.
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.
Caverns typically develop in limestone and other soluble rock formations due to the process of chemical weathering, where water dissolves minerals within the rock. Over time, this erosion creates underground cavities that can develop into caverns through the combination of water flow, pressure, and time.
Sea caves.
The only caves that can form dry are; Rock-shelters eroded out by wind-blown sand. Talus Caves: voids between landslipped boulders and their parentrock-face. Mass-movement fissures: formed by a type of landslip. Lava Tubes - rather stretching the point because they result from molten lava flowing out from beneath a solidified crust. Caves formed in limestone - as most caves are - arekarst features, i.e. result from dissolution of the rock by weakly-acidic ground-water. Although such caves can subsequently lose their formative streams and so become dry, they were not formed dry and do not develop any further.
A subterranean cavern is an underground chamber or cavity formed by natural processes such as erosion, dissolution, or volcanic activity. These caverns can be large or small, with unique features such as stalactites, stalagmites, and underground lakes.
The Eisriesenwelt, in the Tennengebirge Alps of Austria. 42km of surveyed passages. The cave itself is in limestone, but large parts of it are lined with ice and ice-formations. Part now a show-cave.
Carlsbad Cavern in New Mexico has more than 100 caves. A large cave named "The Big Room" is almost 4,000 feet long, 625 feet wide, and 255 feet high at the highest point. It is the fifth largest chamber in North America and the twenty-eighth largest in the world.
As water flows through a limestone, some of the rock dissolves. This process can lead to the formation of cavities and caves. If a cave becomes too large and unstable to support the overbearing rock, it will collapse, leaving a sink hole at the surface.
