Not quite. Limestone can be quite hard but in any case mechanical erosion is a secondary process consequent upon a sufficiently large conduit forming first.
The primary process is the dissolution of limestone (strictly speaking the calcium carbonate that is its main constituent) by water slightly acidified by absorbing atmospheric carbon dioxide.
The water finds its way through the rock formation by following the tension-cracks, bedding-planes and other discontinuities from sink to rising (spring).
And the term used throughout the English-speaking world is "caving" not "spelunking", which I have heard is actually derisory slang in the US for novice or dilettante cavers. I've mentioned this a few times on Answers by now!
What else can I help you with?
What is the following causes of chemical weathering of rock and soil except?
The causes of chemical weathering include exposure to water, oxygen, carbon dioxide, and acids. Erosion is a physical weathering process, not a chemical one.
What kind of weathering causes mineral composition of rock to change?
Chemical weathering
What causes weathering on marble and limestone?
acid rain causes the marbel statues to arode
What is the natural process that causes rock to breakdown?
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.
How do acids in groundwater cause chemical weathering?
It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.
Is limestone dissolved by carbonic acid chemical or mechanical?
The dissolution of limestone by carbonic acid is a chemical process. Carbonic acid reacts with the calcium carbonate in limestone to form calcium bicarbonate, which is soluble in water. This chemical reaction causes the limestone to dissolve.
What chemical weathering called oxidation causes and nbsp?

What gas causes chemical weathering?
Oxygen is the major gas that is the cause chemical weathering.
What type of chemical weathering causes a karst landscape such as a cavern?
Carbonation, a type of chemical weathering where carbon dioxide in rainwater reacts with limestone to form carbonic acid, is the primary process that creates karst features like caves and sinkholes. Over time, this acidic water dissolves the limestone, creating underground voids and caverns in the process.
Two examples of chemical and physical weathering?
Chemical weathering involves the breakdown of rocks through chemical reactions. For example, the gradual dissolution of limestone by acidic rainwater is a common form of chemical weathering. Physical weathering, on the other hand, involves the breakdown of rocks without changing their chemical composition. An example is freeze-thaw weathering, where water seeps into cracks in rocks, freezes, expands, and causes the rocks to break apart over time.
What type of weathering causes the formation of an underground cave?
This would usually be caused by the dissolution of soluble rocks such as limestones. Dissolution is a chemical weathering process.
What causes erosion of limestone?
Erosion of limestone can be caused by chemical weathering, where acidic rainwater dissolves the calcium carbonate in limestone, or by physical weathering, where wind, water, or ice break down the rock over time. Human activities like mining and quarrying can also contribute to the erosion of limestone.

Explain the difference between mechanical and chemical weathering?
Mechanical weathering is the breakdown of rocks into smaller pieces without altering their chemical composition, usually by processes such as frost wedging or root expansion. Chemical weathering, on the other hand, involves changes in the chemical composition of rocks due to reactions with substances like water, acid rain, or oxygen, leading to the breakdown of minerals.
