Acid deposition can be caused by natural sources such as volcanoes but it is mainly caused by the release of sulfur dioxide and nitrogen oxide during fossil fuel combustion when these gases are discharged into the atmosphere they react with the water oxygen and other gases already present there to form sulfuric acid ammonium nitrate and nitric acid.
What happens to granite due to acid rain.
Acid precipitation affects stone primarily in two ways.
Of all the building stones granite is the least susceptible to acid rain because its composition is of feldspar and quartz both of which resist attacks of acid.
When the sulfur dioxide dissolves in the water in the clouds it makes acid rain rainwater that is more acidic than normal.
Prevailing winds transport the acidic compounds hundreds of miles often across state and national borders.
The chemicals fall to earth as acid rain.
Acid deposition more commonly known as acid rain occurs when emissions of sulfur dioxide so2 and nitrogen oxides nox react in the atmosphere with water oxygen and oxidants to form various acidic compounds.
These acidic compounds.
Acid deposition includes more than just acid precipitation in the.
Acid rain harms fish and trees but it also makes chemical weathering.
Acid rain still occurs but its impact on europe and north america is far less than it was in the 1970s and 80s because of strong air pollution regulations in those regions.
