Acid Rain

rainfall made so acidic by atmospheric pollution that it causes environmental harm, chiefly to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides which combine with atmospheric water to form acids.

when fossil fuels are burned chemicals like carbon dioxide and sulfur oxide escapes into the air these molecules dissolves in the water in the clouds and make the rainwater more acidic than normal 

Causes of acid rain

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.

Effects of acid rain

Effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife

Because nitrogen oxides are created in the process of burning coal and other fossil fuels, some power plants are changing the way they burn coal. A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power.
