It contributes to pollution in a variety of ways including: damage to plants and the wildlife The trees are weakened, cannot grow properly and are attacked by viruses, fungi and pests. Acid deposition: A complex chemical and atmospheric phenomenon that occurs when emissions of sulfur and nitrogen compounds and other substances are transformed by chemical processes in the atmosphere and then deposited on earth in either wet or dry form. Lake acidification and fish loss in the Adirondacks, Green Mountains, and Sierra Nevada make national news. These chemicals in acid rain are formed when oxides of nitrogen and sulphur come in contact with rainwater. Acid precipitation is a growing problem in America and Europe, causing government agencies to instill laws and programs to counteract the negative effects of acid rain. 3. Definition of Acid Rain Precipitation that has a pH of less than that of natural rainwater (which is about 5.6 due to dissolved carbon dioxide). Acid rain is a term coined in 1852 by Robert Angus Smith, a Scottish scientist who conducted rainwater experiments in industrial regions throughout Scotland and England. It is formed when sulphur dioxides and nitrogen oxides, as gases or fine particles in the atmosphere, combine with water vapour and precipitate as sulphuric acid or nitric acid in rain, snow, or fog. 5. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are alkaline. ACID RAIN PPT 1. n. Precipitation abnormally high in sulfuric and nitric acid content that is caused by atmospheric pollutants. The pH scale can be used to measure how acidic or basic a solution is. This change has disturbed the climatic pattern of the earth. Normal acidity of rain water is 5.6 H20 (1) + C02 (g) H2C03 (aq) Because of S02 & N02 gases as pollutants in atmosphere. The wet forms, popularly called acid rain, can fall to earth as rain, snow, or fog. What does that mean? Acid rain rapidly increases the rate of weathering on rocks containing carbonate minerals as well as other types of rock, but also has adverse effects on manmade structures and the environment. HWS: Finger Lakes Institute Precipitation is naturally acidic due to the carbon dioxide in air reacting with water in air to form carbonic acid (recall the carbon cycle). Since rain naturally has things dissolved in it, it will always be slightly acidic. In this post, we're going over what acid precipitation is and the effects of acid rain on plants and animals. A gargoyle that has been damaged by acid rain. Acid rain and the dry deposition of acidic particles contribute to the corrosion of metals (such as bronze) and the deterioration of paint and stone (such as marble and limestone). Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water.Biologically harmful precipitation, mostly caused by pollutants released by human activity. Chemicals in acid rain are acids like nitric acid and even sulphuric acid present in the polluted air. … • Acid rain refers to the presence of excessive acid content in the atmosphere and also in the precipitation water(rain, snow, mist, fog etc). Smog is the visible gaseous and particular matter concentrating near the earth's surface particularly in the cities due to SO 2, CO 2, factory and traffic emission and meteorological conditions.When different gases like SO 2, NO 2, N 2 O, NO 2, unburnt hydrocarbons etc. Acid Rain Causes Find definitions for: ac'id rain' Pronunciation: precipitation, as rain, snow, or sleet, containing relatively high concentrations of acid-forming chemicals, as the pollutants from coal smoke, chemical manufacturing, and smelting, that have been released into the atmosphere and combined with water vapor: harmful to the environment. The rain sometimes falls many miles from the source of pollution but wherever it falls it can have a serious effect on soil, trees, buildings and water. Acid Rain Definition. Direct damage to trees occurs when SO2 blocks the pores on the leaves, through which the trees takes in the air they need to live. Acid deposition includes acidic rain as well as other forms of acidic wet deposition—such as snow, sleet, hail, and fog (or cloud water). The acid rain will kill trees and damage buildings made from limestone. Acid rain is a pollution problem caused by the release of acidic gases into the atmosphere. © 2012 Farlex, Inc.

The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere. Acid rain is a term referring to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. When there is precipitation, the droplets fall to earth as rain, snow, or sleet. What is The Affects of Acid Rain on Soil Biology? However, the concept of global warming is quite controversial but the scientists have provided relevant data in support of the fact that the temperature of the earth is rising constantly. Acid rain is rain that has been made acidic by certain pollutants in the air. The dry forms are acidic gases or … Pure water has a pH of 7, and, generally, rainfall is somewhat on the acidic side (a bit less than 6). The "acid" in acid rain comes from sulfur oxides and nitrogen oxides, products of burning coal and other fuels and from certain industrial processes. Smog And Acid Rain Smog. These acids along with rain water percolate down through soil profiles. Precipitation laced with pollution, produced predominantly by power plants that burn coal of variable purity, generating SO2 and NO2, lowering the pH of precipitation Segen's Medical Dictionary. Acid rain Definition: Falling rain (or snow) which has become acidic ( pH less than 5.6) as a result of its combination with gaseous pollutants, such as sulphur dioxide ( SO 2 ) and nitrogen oxides (NO x ) .
