Which process is most likely responsible for the formation of limestone caves
A. ABRASION
B. OXIDATION
C. Carbonation
D. Hydrolysis
C. Carbonation
The process most likely responsible for the formation of limestone caves is C. Carbonation.
Carbonation is a chemical weathering process that occurs when carbon dioxide in the atmosphere combines with water to form a weak acid called carbonic acid. This acid reacts with the calcium carbonate in limestone rocks, dissolving it slowly over time. As the rocks dissolve, they create openings and pathways for water to flow through. Over thousands or even millions of years, this flowing water carves out caves and other underground formations.
