Weathering (deterioration caused by exposure to the environment) is a natural part of the normal geologic cycle. For example, the process of weathering has turned the hard rocks of the Piedmont Plateau into the soft sediments washed downriver to form the Coastal Plain. Similar weathering processes affect the stones in buildings and monuments.

The possible importance of dry deposition to the grain removal process remains an open question in the weathering of carbonate stone (19). The reprecipitation of calcite from solutions trapped in the stone pores, particularly in porous limestone surfaces, also increases the complexity of the grain loss process.

How does weathering affect limestone? – Restaurantnorman.com
Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock. Carbonic acid is especially effective at dissolving limestone.

How does chemical weathering affect the landscape? Chemical weathering changes the molecular structure of rocks and soil. Sometimes, chemical weathering dissolves large portions of limestone or other rock on the surface of the Earth to form a landscape called karst.

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 one cause of increased carbon dioxide in the atmosphere.
