The process most likely responsible for the formation of limestone caves is carbonation.
The process most likely responsible for the formation of limestone caves is carbonation.
To understand why, we need to know what limestone is. Limestone is a sedimentary rock mainly composed of calcium carbonate (CaCO3) that forms over many years through the accumulation of marine organisms such as coral or shell fragments.
The process of carbonation involves the reaction of carbonic acid (H2CO3) with calcium carbonate in limestone. Carbonic acid is formed when carbon dioxide (CO2) dissolves in water. This acid reacts with the calcium carbonate, causing it to dissolve and ultimately creating voids or cavities in the limestone. Over time, these voids can enlarge and form intricate cave systems.
So, to answer your question, carbonation is the process most likely responsible for the formation of limestone caves.
