Rates of Weathering edHelperLimestone Wikipedia

It is the carbonization of calcite that causes the increased rate of weathering of limestone The material found in sediment grains also affects the rate of weathering The mechanical weathering of rocks like shale and sandstone causes their grains to break up over time and become sand and clay particl Why Well the grains in these two types of rocks are not cemented together firmly Rocks Limestone is a sedimentary rock which is often composed of the skeletal fragments of marine organisms such as coral foraminifera and molluscs Its major materials are the minerals calcite and aragonite which are different crystal forms of calcium carbonate CaCO 3

Physical Characteristics of Limestone SciencingThe Erosion of Carbonate Stone

Limestone is also subject to mechanical weathering especially in dry climates by the abrasive action of wind carrying rock fragments and other debris This combination of chemical and mechanical weathering makes limestone very vulnerable to deterioration when exposed to the atmosphereAll materials that are exposed to the outdoor environment are subject to degradation caused by natural weathering process Since the mid 19th century air pollution has been suspected of accelerating the degradation of natural and man made materials Limestone and marble are two types of stone used in the construction of buildings and monuments and in the creation of carved stone statuary

Chemical weathering especially hydrolysis and oxidation is the first stage in the production of soils How does it occur There are different types of chemical weathering the most important are Solution removal of rock in solution by acidic rainwater In particular limestone is weathered by rainwater containing dissolved CO2 this process is sometimes called carbonation Hydrolysis Sometimes chemical weathering dissolves large portions of limestone or other rock on the surface of the Earth to form a landscape called karst In these areas the surface rock is pockmarked with holes sinkhole s and cav
