=__**Acid Rain**__= Acid rain is generally found as precipitation with high levels of nitric and sulfuric acids. Acid rain can also occur in the shape of snow, fog, and minuscule bits of dry material that drop to Earth. In parts of the world where there is dry weather, acid gas and acid dust are prominent. The lakes and streams of the world are all surprisingly slightly acidic. Usually, heavy rainstorms or melting snow can cause the acidity in lakes and in streams to increase. Rotting vegetation and erupting volcanoes release a few of the many chemicals that can cause acid rain, but acid rain is mainly caused due to daily human activities. The biggest miscreant is the burning of fossil fuels by coal-burning power plants, factories, and traveling vehicles. Water is soluble with acid. When water (the solvent) is contaminated with acids (the solutes) it can cause big problems in many ways. Even though the solution is unsaturated the change in pH of the solution is enough to hurt trees and kill animals.
