| acid rain |
Precipitation (eg rain, snow) that has a lower pH level than normal. Acid precipitation is created when atmospheric water combines with sulfur dioxide and nitrous oxide emissions. These emissions are by-products of the combustion of fossil fuels. Acid preciptation can harm plant and animal life and alter soil conditions.

| acid rain |
The precipitation of dilute solutions of strong mineral acids, formed by the mixing in the atmosphere of various industrial pollutants (primarily sulfur dioxide and nitrogen oxides) with naturally occurring oxygen and water vapor.

| acid rain |
Rainwater that has an acidity content greater than the postulated natural pH of about 5.6. It is formed when sulfur dioxides and nitrogen oxides, as gases or fine particles in the atmosphere, combine with water vapor and precipitate as sulfuric acid or nitric acid in rain, snow, or fog. The dry forms are acidic gases or particulates.

| acid rain |
Also called acid precipitation or acid deposition, acid rain is precipitation containing harmful amounts of nitric and sulfuric acids formed primarily by nitrogen oxides and sulfur oxides released into the atmosphere when fossil fuels are burned. It can be wet precipitation (rain, snow, or fog) or dry precipitation (absorbed gaseous and particulate matter, aerosol particles or dust). The term pH is a measure of acidity or alkalinity and ranges from 0 to 14. ...

| acid rain |
Rain that has become more acidic than normal (a pH below 5.0) as certain oxides present as airborne pollutants are absorbed by the water droplets. The term is often applied generically to all acidic precipitation.
