Generally, Carbonic Acid is the agent concerned, though similar weak acids such as Humic Acid, and a small amount of Nitric Acid produced in the atmosphere may also play their part.

These acids gradually dissolve the limestone, and in the case of the Carbonate, are precipitated again as stalactites and stalagmites.

What dissolved the limestone to form the caves?

The forests that grows over the limestone forms mulch that produces the acid required. That's true but the prime solvent is Carbonic Acid: atmospheric carbon dioxide dissolved into rain-water.


What process creates cave?

Caves form when acidic rain dissolved limestone.


What may dissolved limestone form?

Dissolved limestone can form stalactites and stalagmites in caves through the process of precipitation when the calcium in the limestone re-crystallizes. It can also contribute to the formation of karst landscapes such as sinkholes and caves due to the chemical weathering of the rock.


Is rainwater a weak acid that dissolves limestone to form caves?

yes


When rain soaks aways rock below the ground to form caves are called?

Right - rain absorns atmospheric CO2 to become slightly acid. When this water percolates through discontinuities in limestone, the rock is dissolved by this carbonic acid (an example of chemical weathering), and over time the conduits this creates enlarge and coalesce to form caves.


What type of rock is worn away by weak acid in water to create a cave?

Limestone is the type of rock that is commonly dissolved by weak acids in water, such as carbonic acid, to form caves through a process known as chemical weathering.


Can granite dissolve slowly in acid water to form caves?

No, only limestone dissolves.


Where would you find stalagmites stalagmites?

In caves formed in limestone - as are most of the world's caves although not all such caves contain stalagmites and stalactites. They are precipitations of calcite dissolved from the host limestone by carbonic acid - rain water acidified by atmospheric carbon dioxide dissolved in it.


How are carbonic acid caverns and dripstone related?

Carbonic acid plays a key role in the formation of dripstones in caves. When carbonic acid in rainwater interacts with limestone, it creates a chemical reaction that dissolves the limestone and forms caves. As the water drips through the cave, it leaves behind mineral deposits that accumulate over time to form dripstones like stalactites and stalagmites.


Is carbonic acid an acid that forms caves?

Yes, carbonic acid (H2CO3) can dissolve limestone and other minerals in rocks to create caves over long periods of time through a process called carbonation. Carbonic acid reacts with the calcium carbonate in limestone to form calcium bicarbonate, which is more soluble and leads to cave formation.


Why do caves form in only certain types of rocks?

Caves typically form in rocks that are soluble in water, such as limestone and gypsum. These rocks can be dissolved by carbonic acid in rainwater, creating cavities over time. So, caves are more likely to form in rocks that are easily eroded by water.


Where do caves usually form?

Caves usually form in areas with limestone or other soluble rocks that can be dissolved by water over long periods of time. Common locations for cave formation include regions with karst topography, such as in limestone landscapes or near volcanic activity, where lava tubes can create caves.
