  "term": "Acid Deposition",
  "field": "Environment",
  "definition": "1. Combination of wet deposits from the atmosphere, consisting of droplets of sulfuric acid and nitric acid dissolved in rain, sleet, and snow, and dry deposits from the atmosphere, consisting of particles of sulfate and nitrate salts. These acids and salts are formed when water vapor in the air reacts with the air pollutants sulfur dioxide and nitrogen dioxide.\n\n2. 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, often far from the original sources, and then deposited on earth in either wet or dry form. The wet forms, popularly called \"acid rain\", can fall as rain, snow, or fog. The dry forms are acidic gases or particulates.\n\n3. Acidic materials that falls from the atmosphere to the Earth in either wet (rain, sleet, snow, fog) or dry (gases, particles) forms. More commonly referred to as acid rain, acid deposition has two components: wet and dry deposition.\n\n4. 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, often far from the original sources, and then deposited on earth in either wet or dry form. The wet forms, popularly called \"acid rain,\" can fall to earth as rain, snow, or fog. The dry forms are acidic gases or particulates.\n\n5. Acidic material that falls from the atmosphere to the earth in either wet (rain, sleet, snow, or fog) or dry (gases and particles) forms.\n\n6. A complex chemical and atmospheric process whereby recombined emissions of sulfur and nitrogen compounds are redeposited on earth in wet or dry form.\n\n7. 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, often far from the original sources, and then deposited on earth in either a wet or dry form. The wet forms, popularly called acid rain,\" can fall as rain, snow, or fog. The dry forms are acidic gases or particulates.\" (EPA 1992, 1)\n\n8.
