How many days does it take the acid rain to clear up?
It is not a matter of days because it is caused by humans. If
acid rain was a natural process, then nature would take care of it
when it was needed. But since acid rain is created by humans,
nature has no correcting mechanism for it, so it will remain
unchecked until we humans do something about it. And, unfortunatly,
that will probably take more than days, weeks, or months. Maybe
Acid rain probably started after the industrial revolution. In Man's quest to industrialize, we created so many industries without considering or bothering about the impact of the pollution we caused on the environment. Acid rain happens when there is significant amount of pollution in the air, these chemical compounds mix with rain clouds and therefore when it rains the polluted water causes "acid rain" or polluted rain.
statues and many buildings in areas close to cities, acid rain is not so common in the countryside as it is created by sulphur in fossil fuels and when the fuel is burnt it creates sulphur dioxide which is in aid rain there are not as many cars in the country side i.e. there's not as much sulphur dioxide meaning not as much acid rain.
Acid rain is 'sulphuric acid'. Sulphur dioxide is a waste, pollutant gas produced by many industrys. When released into the atmosphere the sulphur dioxide dissolves into the rainwater to form this 'sulphuric acid'. Acid rain is bad as it corrodes buildings, destroys plants and their root sytems, affects aquatic life (as acid rain changes the pH of pond water making it acidic), etc.
There are many forms of acid rain that are seen around the world. In parts of the world where wet weather, there is acid rain, acid snow, and acid fog. In parts of the world where there is dry weather, there is acid gas and acid dust. All of the lakes and streams in the world are normally slightly acidic. Heavy rainstorms or melting snow can cause acidity in lakes and in streams to
