It s almost like Thriller. . .
Acid rain can effect all parts of our environment, as well as our lives.
Unpolluted rain has a pH of 5.6, as a result of natural carbon dioxide gases it picks up in unpolluted air. Today, pH levels of rain are much lower as a result of industrial pollutants in the atmosphere. Water droplets fall from clouds, picking up harmful particles and chemicals on their way to the earth's surface. Thus, acid rain is a direct threat to our environment and lives. In studying the age, condition, and other properties of gravestones, it is possible to determine the rate in which limestone is deteriorated as a result of acid rain and related weathering.
