Conversely, when atmospheric conditions are bringing moisture to the region, it acts as a source of water vapor, which, when added to the upward motion of air, produces rain their findings suggest that land surface changes in response to both climate and human activity could be significant. Although rain is most commonly thought of as wet, acid rain can come in both a wet or dry form based on how the acidic materials fall from the atmosphere when the materials are in a wet form. People in europe have been talking about acid rain—more appropriately acid deposition, because acid is present in not only rain but snow, fog, and dry particles—for a long time, he said in 1872, the british chemist robert angus smith coined the term acid rain in air and rain: the beginnings of a chemical climatology. Acid rain is made up of water droplets that are unusually acidic because of atmospheric pollution, most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. These gases dissolve in droplets of moisture in the atmosphere and eventually produce an acid rain acid rain can have a direct effect on plants (phytotoxicology) or on the soil structure of the.
Second to water vapor, carbon dioxide is the next leading contributor to atmospheric greenhouse gases the massive output of anthropogenic carbon dioxide is an international pollution issue that has been extensively addressed since the rapid escalation of carbon dioxide to its current atmospheric concentration of 395 ppm, the united nations and other international assemblies have had the. An analysis of the acid rain and the issues of pollution in atmospheric moisture an analysis of air pollution in our industrialized world of acid rain, a. Acid rain is caused by reactions in the environment nature depends on balance, and although some rain is naturally acidic, with a ph level of around 50, human activities have made it worse.
Acid rain, for example, is formed when emissions of sulfur dioxide and nitrous oxide combine with moisture in the air to create acidic precipitation this acid rain can acidify lakes and soils it can also cause structural damage to buildings and monuments, especially those made of limestone or marble. What is acid rain acid rain is the common name for acidic deposits that fall to earth from the atmosphere the term was coined in 1872 by english chemist robert angus smith to describe the acidic precipitation in manchester, england. Acid rain, or more accurately acid precipitation, is the term used for describing rainfall with a ph level lower than 56 this type of pollution is a matter of great debate currently due to its potential of causing environmental damages all across the world.
The main components of atmospheric air are nitrogen and oxygen both of them form 9903% of clean, dry air other contents are water vapor and trace gases, which account for roughly 025% and 097% of the atmosphere by mass respectively. Acid rain is more properly called acid precipitation or wet deposition: the depositing of pollutant chemicals on the ground, plant growth and man-made structures via a wet medium such as fog, rain or snow. the effects of acid precipitation on the environment to this day, humans have used earth's natural resources carelessly, which has led to many environmental issues such as air pollution, which has lead to the formation of acid rain acid rain is one of the most genuine environmental issues faced by our society today.
Nevertheless, in january 1986, president reagan's special representative on acid rain together with canada's representative on the high-level acid rain panel, concluded in their report that acid rain is a serious environmental problem.

Global warming hysteria, the acid rain scare, and other money-making megamyths the greed and power lust of politicians and paid-off scientists have gravely damaged public respect for scientific endeavor. Chemist robert angus smith coined the term acid rain in 1852, about 20 years before he published work detailing a connection between pollution in the air and elevated acidity levels that were appearing in manchester, england, following the start of the industrial revolution there in the 1700s.
The purpose of this experiment was to find out how acid rain affects the growth and health of plantsi became interested in this experiment when i saw a movie about toxins in the environment at schooli researched online about environmental toxins and became fascinated with acid rain. ----- acid rain panel report executive summary in january 1982, the office of science and technology policy asked professor william a nierenberg, the director of scripps institution of oceanography, to assemble and chair a scientific panel on acid rain. How rain is dependent on soil moisture date: march 6, 2015 source: eth zurich summary: it rains in summer most frequently when the ground holds a lot of moisture however, precipitation is most likely to fall in regions where the soil is comparatively dry this is the conclusion reached by researchers following an analysis of worldwide data.
