A cave system - as simple as that. :-)
Sometimes the system is named as So-&-So Cavern, especially if part of it has been modified to form a show-cave, but the formal and most used term is still "cave".
CAVES - just that. The word "cavern" is occasionally applied to large chambers ("rooms" in US cavers' parlance,I think) and by their owners, to show-caves; but the normal word in all English-language caving speech and text, for any natural subterranean voidirrespective of type and size, is just, CAVE!
There are 117 known caves within Carlsbad Caverns National Park.
That they were stone age people that lived in caves and hunted large animals, like bison, horse, mammoth, etc.
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.
Weakly acidic groundwater can slowly dissolve minerals like calcite in sandstone, but it typically does not create large caves in sandstone formations. Sandstone is more resistant to dissolution compared to limestone, which is more commonly associated with cave formation due to its high solubility in acidic water. Sandstone may exhibit some minor features like dissolution pockets or small cavities, but it is not a common host rock for the development of extensive cave systems.

The nation of Chile has an extensive judicial system. Chile is a democratic country and its laws are based to a large degree on European republics.
Most caves are small but some are very large and complex. There is no standard size and finding an "average" is not very useful.
A plain?
detrital slope
Nope. No mountains in sight. Not even Kilimanjaro. It's flats grounds all the way... Obviously there is. Kango Caves for one(in the Cape Province (which is in South Africa (which is in Africa (South)))) There are also extensive caves below the Nullarbor Plain in Australia, and that's "flat ground all the way"!
