What Causes Weathers Marble And Limestone

This causes the limestone to dissolve.

What causes weathers marble and limestone.

Weathering is the breakdown of rock by physical chemical or biological processes. Rain water h 2 o in the clouds dissolves some of the so 2 a pollutant from industrial manufacturing. Limestone is soluble in acidic water. Chemical weathering weathers marble and limestone.

In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. This makes weak sulphuric acid h 2 so 4. When it mixes with rain water will create carbonic acid rain which weathers marble and limestone so carbonic acid weathers marble and limestone. It slowly erodes away the surface over very long periods of time.

Chemical weathering produce weak acid that weathers rock. Stone surface material may be lost all over or only in spots that are more reactive. 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.

In simple terms acid rain is a weak sulphuric acid and this is a significant cause of chemical weathering. Mechanical weathering causes rock to flake off. Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone. The video in figure 2 shows how acid rain weathers limestone.

Chemical weathering causes rust on some rock. 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. Water is the primary cause for the weathering of marble and limestone.
