What Causes Weathers Marble And Limestone

This makes weak sulphuric acid h 2 so 4.

What causes weathers marble and limestone.

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. It slowly erodes away the surface over very long periods of time. When it mixes with rain water will create carbonic acid rain which weathers marble and limestone so carbonic acid weathers marble and limestone.

Water is the primary cause for the weathering of marble and limestone. Chemical weathering produce weak acid that weathers rock. This causes the limestone to dissolve. Mechanical weathering causes rock to flake off.

Limestone is soluble in acidic water. 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. Mechanical weathering roots pry apart and cracks in rocks. In simple terms acid rain is a weak sulphuric acid and this is a significant cause of chemical weathering.

Release of pressure exfoliation. Chemical weathering weathers marble and limestone. Rain water h 2 o in the clouds dissolves some of the so 2 a pollutant from industrial manufacturing. The video in figure 2 shows how acid rain weathers limestone.

Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. What causes weathers marble and limestone.
