Question

How does carbonation lead to the formation of caves?(1 point) Responses Oxygen and water from the atmosphere react chemically with the substances in limestone, causing it to dissolve. Oxygen and water from the atmosphere react chemically with the substances in limestone, causing it to dissolve. Water in rain reacts with carbon dioxide in the atmosphere, creating carbonic acid, which then reacts with rocks such as limestone. Water in rain reacts with carbon dioxide in the atmosphere, creating carbonic acid, which then reacts with rocks such as limestone. Oxygen compounds such as nitrogen oxides cause acid rain to form, which reacts with rocks such as limestone. Oxygen compounds such as nitrogen oxides cause acid rain to form, which reacts with rocks such as limestone. Water from the environment reacts with rocks such as limestone to create weaker compounds, causing some rocks to transform into clay.

Answer 1

The correct response is: **Water in rain reacts with carbon dioxide in the atmosphere, creating carbonic acid, which then reacts with rocks such as limestone.**

This process leads to the dissolution of limestone, forming caves over time. Carbonic acid is a weak acid that can gradually dissolve calcium carbonate, the primary component of limestone, which facilitates the formation of underground cavities and caves.
