This would usually be caused by the dissolution of soluble rocks such as limestones. Dissolution is a chemical weathering process.
Lake Eola was formed when an underground cave collapsed and was clogged by sediment
A cave is an agent of erosion. More specifically, chemical weathering forms caves.

It is called weathering.
Principally chemical as the limestone is dissolved by carbonic acid (rain-water acidified by absorbed atmospheric CO2). As the cave develops mechanical weathering of its stream-passages may contribute, by abrading the rock with sand carried in the stream.
chemical change
In most caves this process is the dissolution of calcium carbonate.

Chemical weathering, esp. in carbonate rocks, aided to some extent as the conduit develops by mechanical erosion by the stream.
it is a cave formation deposited by dripping or flowing water . it is NOT a natural bridge
a cave
An underground cave is a hollow area beneath the Earth's surface that is typically formed by the erosion of rock or soil. These caves can vary greatly in size and shape and are often home to unique geological formations and ecosystems. Many underground caves are popular destinations for exploration and tourism.
the dripping of mineralized solutions and the deposition of calcium carbonate. The corresponding formation on the ceiling of a cave is known as a stalactite. If these formations grow together, the result is known as a column. is what happens but I think the process is called Dissolution
ALL caves are underground by definition. It's where they are! :-)
