Limestone is made mostly of calcium carbonate and calcium sulfate. Limestone is eroded by water as the calcium carbonate and calcium sulfate of the stone disolves into running water.
Also a factor: other things dissolved in the water. Carbon Dioxide disassociates in water becoming carbonic acid. This means that the more Carbon Dioxide in the water, the more acidic it is. The more acidic the water, the faster erosion can occur.
When acidic ground water packed with lots of carbon dioxide is saturated with minerals - dissolved limestone - and that water enters an air filled chamber, the amount of mineral it can hold can suddenly change. This causes excess mineral to come out of solution as the water drips off the ceiling and onto the floor below into structures called Speleothem.

What else can I help you with?
What are formed when limestone found in the Earth has been eaten away?
Caves and sinkholes are formed when limestone is dissolved by underground water, creating underground spaces. Karst topography, characterized by these features, is a landscape formed by the dissolution of soluble rocks like limestone.
What is chemical weathering when limestone rock is dissolved by natural acids like carbonic acid?
Chemical weathering occurs when the minerals in rocks are broken down by chemical processes. In the case of limestone, the calcium carbonate in the rock reacts with carbonic acid in rainwater, forming calcium bicarbonate which dissolves the limestone. This process is known as carbonation and is a common form of chemical weathering on limestone rocks.
What can rain water do to rocks like limestone?
Rain water can gradually dissolve limestone rocks through a process called carbonation, where carbon dioxide from the air combines with water to form a weak acid. Over time, this acid can react with the minerals in limestone, causing it to break down and form cracks and cavities.
Carbonic acid forms when carbon dioxide is absorbed into water The action of carbonic acid on may produce sinkholes caverns and formations like stalagmites?
Yes, carbonic acid can react with calcium carbonate in rocks to dissolve them over time, creating sinkholes, caverns, and formations like stalagmites in a process known as chemical weathering. This is a slow process that occurs over hundreds or thousands of years depending on the conditions.
Chemical rocks are formed by?
By precipitation or evaporation of saturated solutions.
What are the most common rocks in Carlsbad Caverns in New Mexico?
Limestone.
Caverns when rocks such as limestone are dissolved by a mixture of water and?

What type of rocks and minerals would you expect to find at the Carlsbad caverns national park?
the rocks in carlsbad is limestone
How and where do most caverns form?
Most caverns form through a process called speleogenesis, which occurs when groundwater dissolves limestone or other soluble rocks over millions of years. These dissolved materials create openings and passages underground, eventually forming caverns. The most common locations for cavern formation are in areas with thick limestone deposits, such as karst regions.
How are caverns made?
Caverns are formed through a process of chemical weathering and erosion of soluble rocks, such as limestone, by percolating water. Gradual dissolution of the rock over time creates underground voids that eventually expand to form caverns. Additional factors like tectonic activity and the presence of natural faults can also contribute to cavern formation.
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 type of minerals or rocks are found in luray caverns?
Luray Caverns in Virginia primarily features formations of limestone, including stalactites, stalagmites, and flowstone. Some other minerals present in the caverns include calcite, aragonite, and gypsum.
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.
Caves are found in Virginia's Valley and Ridge province because the area is underlain by?
limestone and dolomite bedrock, which are easily dissolved by water, forming caves and caverns in the Valley and Ridge province of Virginia. The acidic groundwater slowly dissolves the carbonate rocks over time, creating underground cavities and networks of caves.
Which rocks can be dissolved with weak acid?
Limestone and marble are two common rocks that can be dissolved by weak acids like vinegar or lemon juice. This is because they both contain calcium carbonate, which reacts with acid to form soluble calcium compounds.
What types of bedrock are dissolved most easily by running water?
Bedrocks such as limestone, dolomite, and gypsum are easily dissolved by running water due to their solubility in water. These rocks contain minerals that are easily weathered and dissolved, resulting in the formation of features like caves, sinkholes, and underground rivers.
Which type of weathering happens to limestone faster than to other rocks?
it is dissolved by weak acids in rainwater
