How does weathering affect limestone?

Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is …

How does acid precipitation affect marble and limestone buildings?

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.

Climbing on Limestone: A complete guide

The calcium carbonate composition of the limestone causes the rock to react and erode when it comes in contact with water depending on the fluid's acidity. For example, rain water is acidic as it typically has a pH between 5.6 and 5.8. The more acidic the fluid, the more the limestone will react and erode.
