That is a much harder question for a caverto answer than you might imagine!
First though you do not need the adjective.Caverns are underground bydefinition!
Each cave is unique but they have common features that include any of passage profiles related to their development, erosion details, sediment deposits, boulder piles, speleothems (fancy word that encompasses stalactites, stalagmites and related deposits), streams, pools, waterfalls(or no water at all), wildlife, geological details.....
One thing that seems obvious is the darkness. Once away from the daylight, if you turn off your lamps,the darkness in a cave is absolute. Even experienced cavers won't normally wait underground in the dark for long before putting at least a small lamp on. It plays a strange trick on you. Hold your hand in front of your face and you think you can see it as a sort of different blackness.
I suggest you ferret around the internet for photos of caves. You can find them on tourist publicity for show-caves but try to ignore the artificial paths, steps and lights, or on caving-club web-sites, etc.
An underground cavern is a large cave or chamber typically found beneath the Earth's surface. These formations are often created through geological processes such as erosion, dissolution of rock, or volcanic activity. Underground caverns can contain unique ecosystems and geological features.
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.
Peak Cavern was formed by the gradual erosion of the limestone rock by underground streams over millions of years. The dissolving of the limestone created a network of passages and chambers that make up the cave system we see today.
The four caves at Castleton are Peak Cavern, Speedwell Cavern, Treak Cliff Cavern, and Blue John Cavern. Each cave offers visitors unique underground experiences including stunning rock formations, underground rivers, historical artifacts, and beautiful mineral deposits.
Cavern formation is typically caused by the dissolution of soluble rocks (such as limestone) by water, usually through a process called chemical weathering. Over time, the water erodes and dissolves the rock, creating large underground cavities known as caverns.

Dugtrio! After you fix the railroad in the Cavern Zone, walk around and look for him. Sometimes he is underground so just look carefully.
its at the place where there is a long dive spot
Two features formed by underground weathering are caves and sinkholes. Caves are formed by the dissolution of limestone or other soluble rocks, creating underground chambers and passages. Sinkholes are depressions in the ground that form when the roof of an underground cavern collapses.

A cavern is a large underground opening formed by weathering and erosion. This process can occur in various types of rock formations, such as limestone or sandstone. Caverns often feature unique formations like stalactites and stalagmites as a result of dripping water and mineral deposits.
AnsweA cave is a natural underground void large enough for a human to enter, while a cavern is a large cave that was formed chemically (through things like acid rain). Another mining definition for cavern can also be series of connected underground caves. This definition is the scientific term.You can also check for more details -http://wikiuncle.com/index.php?title=Cave_vs._cavern_vs._hollow&redirect=no
people eat the limestone and live in the underground cavern's :) ... actual lol
