Where Would Marble Be Most Effected By Weathering

Acid precipitation affects stone primarily in two ways.

Where would marble be most effected by weathering. The weathering that affects marble the most is chemical weathering. Granite is extremely hard and less affected by the freeze thaw cycle the forces of abrasion and the surface exfoliation processes that are all a part of physical weathering. In dry climates weathering is slow. Stone surface material may be lost all over or only in spots that are more reactive.

Headstones are subjected to weath. Marble is most prone to chemical weathering in a moist warm climate. The pattern of joints fractures and fissures within rock may provide an avenue for water to penetrate. Most gravestones made over the last few centuries are made of a few types of rock.

Marble is typically composed of calcite which dissolves in acid. The weathering process is affected by climatic conditions. Marble like all calcareous rocks is particularly sensitive to degradation by acid chemicals and to weathering. Fine grain rock will usually be more susceptible to chemical alteration but less susceptible to physical disintegration.

Moist and warm climates favor chemical weathering while moist cold climates favor physical weathering. Physical weathering is the toll put on rocks by processes like. The texture of the rock will affect the type of weathering that is most likely to occur. Weathering processes depend upon the pres ence of water the temperature the mineral composition of the rock and its chemical com position.

When sulfurous sulfuric and nitric acids in polluted air react with the calcite in marble and limestone the calcite dissolves. 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. Weathering processes on headstones and monuments alison tymon march 2012 weathering is defined as the breakdown of rock in situ that is without being moved.

When it rains the rain usually has acid in it which dissolves the marble. Marble slate and granite are the big three. A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location. Acid rains are one of the main degradation agents for marble artifacts.

Water ice acids salts plants animals and changes in temperature are all agents of weathering. How does acid precipitation affect marble and limestone buildings.
