Acid rain is rain or precipitation that is acidic due to elevated levels of hydrogen ions caused by emissions of sulfur dioxide and nitrogen oxides reacting with water molecules in the atmosphere. It can harm plants, aquatic animals, and infrastructure through wet deposition. While some sulfur dioxide and nitrogen oxides occur naturally from lightning and volcanoes, governments have taken steps since the 1970s to reduce sulfur dioxide emissions from industry which has led to positive results.
Acid Rain
- 1. Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions.The chemicals found in acid rain can cause paint to peel and stone statues to begin to appear old and worn down, which reduces their value and beauty.
