Acid Rain
Acid Rain is rain water that contains chemicals from industrial processes that are harmful to plant and animal life. Acid rain is a serious environmental problem that affects large parts of the United States and Canada.
Acid rain occurs when fossil fuels such as coal, gasoline, and fuel oils are burned and emit oxides of sulfur, carbon, and nitrogen into the air. These oxides combine with moisture in the air to form sulfuric acid, carbonic acid, and nitric acid.
Acid Rain: Precipitation which has been made acidic by airborne pollutants.
Acid Rain - Air pollution produced when acid chemicals are incorporated into rain, snow, fog or mist.
Acid rain: When strong acids fall from the atmosphere in the form of rain, snow, fog or dry particles. The acid is the result of pollution caused mostly by sulphur oxides and nitrogen oxides that are discharged into the atmosphere by industry.
Acid Rain - Acid rain is a form of acid deposition in which sulphur dioxide and nitrogen oxides transform into acidic particles or vapors in the atmosphere over distances of hundreds to thousands of miles.
Acid Rain
Rain, snow, hail and fog which is acidic, as a result of pollution. Acid rain has a pH lower than 7.
Alkali
Any substance with a pH higher than 7.
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
Atmospheric drops combine with a range of chemical pollutants such as carbon and sulphur dioxide to form rain, mist or snow that is more acid than normal.
acid rain
the acidic rainfall which results when rain combines with sulfur oxides emissions from combustion of fossil fuels.

Acid rain
Rain that has a flamboyantly low pH, due to contact with atmospheric pollutants such as sulphuric oxides.

Acid rain: Rainfall with a pH of less than 7.0. One source is the combining of rain and sulfur dioxide emissions, which are a by-product of combustion of fossil fuels. Also referred to as acid deposition and wet deposition.
Acid Rain: Wet forms of acid deposition. (see: acid deposition)
Acidic: The condition of water or soil that contains a sufficient amount of acid substances to lower the pH below 7.0.
Acid Rain: (See: acid deposition.)
Acidic: The condition of water or soil that contains a sufficient amount of acid substances to lower the pH below 7.0.
Acid Rain occurs when pollutants such as nitrogen oxides and sulphur dioxide from power plant emissions, metal smelting, motor vehicles and industry, combine with water in the atmosphere to form droplets of very weak acid.
Acid Rain - Acidified particulate matter in the atmosphere that is deposited by precipitation onto a surface, often eroding the surface away.
Acid Rain: Rain which is especially acidic (pH <5.2). Principal components of acid rain typically include nitric and sulfuric acid. These may be formed by the combination of nitrogen and sulfur oxides with water vapor in the atmosphere.
Acid Rain
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.

* Acid Rain
Acid rain forms when certain atmospheric gases (primarily carbon dioxide, sulfur dioxide, and nitrogen oxides) come in contact with water in the atmosphere or on the ground and are chemically converted to acidic substances.
A acid rain
Definition (english only)
Rain having a pH less than 5.6.

Acid Rain
Precipitation having a ph lower than the natural range of ~5.2 - 5.6; caused by sulfur and nitrogen acids derived from anthropogenic emissions.

Acid rain:rain that is made more acidic by sulfuric and/or nitric acid in the air, due to the burning of fossil fuels. Active volcano:a volcano that continues to erupt regularly.
'Acid rain' Rain with a very low pH (often below 4.0) resulting from emissions to the atmosphere of oxides of sulfur and nitrogen. Adaptation A confusing word used to mean quite different things.

acid rain. See acid precipitation.
active channel refers to the width and depth of a stream channel at "normal" high winter flow, sometimes also known as bankfull flow.
Many forests, streams, and lakes-and the creatures that live in them-are still suffering damage from acid rain. Even though the problem of acid rain has been reduced, sulfur and nitrogen pollution levels must be brought down further.
The chemicals and heavy metals used in fireworks also take their toll on the environment, sometimes contributing to water supply contamination and even acid rain.
That is a little acidic because even pure rainwater falls through carbon dioxide in the air. Rain with a pH of less than about 5.3 is considered acid rain. Rain in the northeastern states has a pH between 4 and 5. This is serious acid rain.
It can damage trees and lead to acid rain, which can harm lakes and streams and also corrode exposed materials. In the presence of sunlight and volatile organic compounds, NO2 can contribute to the formation of ground-level ozone, or smog.
NOx is a greenhouse gas and is an ingredient of acid rain and smog.
Non-renewable Energy Resources Energy resources that cannot be restored or replenished by natural processes and therefore are depleted through use.
Air Pollutants can travel long distances from their source. During this transport, secondary pollutants such as acid rain and ozone are produced. Tree foliage may act as a filter, concentrating the pollution.

This can contribute to the formation of acid rain. Regulations require that air pollution control equipment remove either 99% of the hydrochloric acid, or that the emissions contain less than four pounds per hour.
