Which process is most likely responsible for the formation of lime stone caves

Answer 1

The process most likely responsible for the formation of limestone caves is called chemical weathering. Limestone is primarily composed of calcium carbonate, which is easily dissolved by weak acids, such as carbonic acid formed by the interaction of water and carbon dioxide in the atmosphere. Over time, the continuous dissolution of calcium carbonate by acidic water causes the gradual erosion and formation of caves. Additionally, underground water flow and the accumulation of sediment also contribute to the formation of limestone caves.
