Q: Deterioration of limestone occurs more rapidly as the concentration of what increases?


Read this paragraph and choose the correct option from the provided answers:

Figure 12.7 Statues made from carbonate compounds such as limestone and marble typically weather slowly over time due to the actions of water, and thermal expansion and contraction. However, pollutants like sulfur dioxide can accelerate weathering. As the concentration of air pollutants increases, deterioration of limestone occurs more rapidly. (credit: James P Fisher III).

 Choices:
