What Happens To Granite Due To Acid Rain
What causes acid rain.
What happens to granite due to acid rain. The term acid rain is a popular expression for the more formal and scientific term acid deposition. 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. 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. Acid rain harms fish and trees but it also makes chemical weathering.
Acid deposition includes more than just acid precipitation in the. Prevailing winds transport the acidic compounds hundreds of miles often across state and national borders. These acidic compounds. Acid precipitation affects stone primarily in two ways.
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. The chemicals fall to earth as acid rain.
