Question

Which process is most likely responsible for the formation of limestone caves? (1 point)
oxidation
carbonation
abrasion
hydrolysis

Answer 1

are you sure

Answer 2

The process most likely responsible for the formation of limestone caves is **carbonation**. This occurs when carbon dioxide in the atmosphere or soil combines with water to form carbonic acid, which can dissolve limestone (calcium carbonate) over time, leading to the formation of caves.

Answer 3

Yes, I am sure. The formation of limestone caves is primarily due to the process of **carbonation**. In this process, carbon dioxide (CO2) from the atmosphere or soil reacts with water to form carbonic acid (H2CO3). This acidic solution can then dissolve limestone (calcium carbonate, CaCO3) over time, creating cavities and passages that develop into caves. This process is well-documented in karst landscapes, where limestone is prevalent. Other processes like oxidation, abrasion, and hydrolysis do play roles in geological processes, but carbonation is the key process in the formation of limestone caves.
