They are formed by the limestone being dissolved by ground-water seeping through the limestone's joints and other fissures.
cavern Sometimes, in names and especially by show-cave owners to impress intending visitors; but the normal word in anyy English-language caving speech or text is simply "Cave" irrespective of type and dimensions.
The limestone, or more accurately its calcium carbonate,has been dissolved from the rock above, in the joints through which the ground-water passes before dripping into the cave. The mineral is then precipitated in the cave air as Calcite, to form a Stalactite on the celing, and a Stalagmite on the floor below. A "column" is simply a stalactite and stalagmite that have met.
It is all thanks to the rock's solubitlity in water, but cave development in any give limestone region is also controlled by the specific geology, hydrology, geomorphology and continued precipitation over 10s or 100s of 1000s of years.
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".
Ellison Cave was formed by the erosion of the rock by water over millions of years. The cave was created as groundwater seeped through the limestone bedrock, dissolving and creating intricate passageways underground. Over time, the cave continued to grow and develop into its current size and complexity.
A cave?

Limestone and limestone formations.
While a funnel-shaped depression of limestone eroded by rainwater is called a limestone pavement or a doline, a cave is a naturally occurring underground void typically formed through chemical weathering and erosion processes such as the dissolution of limestone by acidic groundwater.
A calcite stalactite.
No, a funnel-shaped depression of limestone dissolved by rain is called a sinkhole. A cave is a natural underground void or cavity that is typically larger and more complex in structure than a sinkhole.
A sinkhole is the term used to describe a depression in the ground caused by a cave collapse. It can also be the result of acidic water dissolving limestone.
it is a 'karst' cave, i.e. formed by the action of water on limestone.
I'm not really sure what you had in mind. Given that the cave is in limestone (as the vast majority of them are) there has to be a dimensional limit to the dissolution and erosion processes. The floor is there by default: it is the lowest surface along a passage at that given time in the cave's development.
From dissolution and erosion of limestone by acidic water over time.
Limestone doesn't exactly "help" a cave unless the stalagmite's and such are what you are looking for. Limestone is what creates those.
Jieta Grotto is a limestone cave it is not man-made.
