About this site

2018-04-19  Weathering describes the breaking down or dissolving of rock s and mineral s on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

Weathering on gravestones

Carbonation This process is a form of hydrolysis, which occurs when rain water reacts with anyminerals containing carbonate. It particularly affects limestone, chalk and marble rocks. Rain wa-ter gets into joints or weaknesses and widens the gaps, often causing blocks to fall off. The sur-face of limestone or marble recedes gradually, because the calcium carbonate is being removedby rainwater.

Environmental degradation of marble - unina.it

Acid rains are one of the main degradation agents for marble artifacts. Acid rain contains carbonic, nitric and sulfuric acid, that are produced by oxidation and dissolution in water of gaseous oxides (CO 2, NO 2 and SO 2), present in the air as chemical pollutants.

Environmental degradation of marble - unina.it

Marble surfaces exposed to rain develop a rough "sugary" texture because the calcite grains are loosened as the edges dissolve in the rain water. Marble, like all calcareous rocks, is particularly sensitive to degradation by acid chemicals and to weathering. Acid rains are one of the main degradation agents for marble artifacts. Acid rain contains carbonic, nitric and sulfuric acid, that are ...

Weathering Processes Physical Geography

Weathering is the process that changes solid rock into sediments. With weathering, rock is disintegrated into smaller pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments away from it’s original position. The four forces of erosion are water, wind, glaciers, and gravity. Water is responsible for most erosion. Water can move most sizes of ...
