The vast majority are in limestone uplands of suitable geological, hydrological and long-term climatic conditions. Very simply, as the whole is very complicated and very specific to each cave's own area:
Rain absorbs CO2 from the atmosphere. This creates weak carbonic acid.
The water sinks into the natural tension-cracks ('joints'), faults and other discontinuities in the mass of limestone, and because it is acid, corrodes the rock slowly away.
In time, the resulting mesh of tiny conduits enlarges, the conduits coalesce and eventually discrete stream-passages form.
This all takes many tens or hundreds of thousands of years. Eventually the stream ceases to take that route and the passage is left high and dry.
The water can only flow if it has somewhere to go: outlets - springs or risings - at the base of the limestone where this outcrops, oftenat the foot of the hill as the resulting stream then forms a surface valley.

What causes caverns?
Caverns are typically formed through a process known as karstification, where groundwater dissolves soluble rocks like limestone and carbonate rocks over time. This dissolution, along with other factors such as erosion and tectonic forces, can create underground cavities and passageways that eventually turn into caverns.
Do most caverns form above the water table?
No, most caverns form below the water table. Caverns are typically formed by the dissolution of underground limestone or other soluble rocks by water, and this process usually occurs below the water table where the rocks are saturated with water.
What cuvses caves caverns and sink holes?
Caves, caverns, and sinkholes are typically formed by the dissolution of soluble rocks such as limestone, dolomite, or gypsum by water. Over time, water erodes and dissolves the rock, creating underground cavities and passages. Eventually, these cavities can collapse or become exposed at the surface, forming caves, caverns, and sinkholes.
How was the Bluespring Caverns formed?
Sadly and bizzarely, the one thing missing from this show-cave's own publicity web-site is anything about the cave! It's shown to be a river cave, and there is a photograph of a tour party on a boat - from which it is possible to deduce the cave is a normal, active (still developing) stream cave formed by the dissolution of its surrounding limestone by water.
How old is fantastic caverns in spring field mo?
Fantastic Caverns, like all caves in the Bible Belt are 6500 years old as opposed to other much older caves located in places where education is not considered a sin.
What formed Carlsbad Caverns?
water
What is formed by the dissolution of limestone?
caverns, sinkholes, etc.
How were the Florida cavern formed?
The Florida Caverns are limestone caves and were formed by rain water dissolving the limestone.
What are the two features that are formed by underground weathering?
The two features formed by underground weathering are caves and caverns. Caves are natural underground chambers typically formed in limestone, while caverns are larger caves that often have unique formations such as stalactites and stalagmites.
Carlsbad caverns is erosion or weathering?
Carlsbad Caverns is primarily formed by dissolution, a type of chemical weathering, of the limestone bedrock by acidic groundwater. This process creates the spectacular caves and caverns found in the area.
What causes caverns?
Caverns are typically formed through a process known as karstification, where groundwater dissolves soluble rocks like limestone and carbonate rocks over time. This dissolution, along with other factors such as erosion and tectonic forces, can create underground cavities and passageways that eventually turn into caverns.
What are the caverns that rough water crashes into?
Sea caves (formed in cliffs by wave action)?
Do most caverns form above the water table?
No, most caverns form below the water table. Caverns are typically formed by the dissolution of underground limestone or other soluble rocks by water, and this process usually occurs below the water table where the rocks are saturated with water.

What forces of nature caused carlsbad caverns to form?
Carlsbad Caverns were primarily formed by the dissolving of limestone by acidic groundwater. The caverns were then further carved out by the movement of water, creating the vast network of interconnected caves and caverns underground. The process of cave formation is ongoing, with some areas still being slowly shaped by the forces of nature today.
What is an agaric mineral?
An agaric mineral is a light, chalky deposit of calcium carbonate formed in caverns or fissures of limestone.
