What Causes Weathers Marble And Limestone

Carbon dioxide from the respiration of animals and ourselves is one cause of increased carbon dioxide in the atmosphere.

What causes weathers marble and limestone.

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. Chemical weathering weathers marble and limestone. Weathering is the breakdown of rock by physical chemical or biological processes. It slowly erodes away the surface over very long periods of time.

Mechanical weathering causes rock to flake off. Even natural rainwater is usually slightly acidic but many parts of the world especially urban and industrial areas have significant amount of nitrogen oxides and sulphur oxides as gases mostly from man ma. Chemical weathering causes rust on some rock. Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone.

What causes weathers marble and limestone. This makes weak sulphuric acid h 2 so 4. This causes the limestone to dissolve. Limestone is soluble in acidic water.

Chemical weathering produce weak acid that weathers rock. Release of pressure exfoliation. Rain water h 2 o in the clouds dissolves some of the so 2 a pollutant from industrial manufacturing. Water is the primary cause for the weathering of marble and limestone.

The video in figure 2 shows how acid rain weathers limestone. When it mixes with rain water will create carbonic acid rain which weathers marble and limestone so carbonic acid weathers marble and limestone. Stone surface material may be lost all over or only in spots that are more reactive.
