Causes of acid rain. The biggest sources are coal-burning power plants, factories, and automobiles. This allow moisture to escape, dehydrating the plant. The ecological effects of acid rain are most clearly seen in the aquatic, or water, environments, such as streams, lakes, and marshes.Acid rain also falls directly on aquatic habitats. and pollutes the water. The waters PH balance drops and it becomes more acidic. This process may result in oxygen depletion of the water body after the bacterial degradation of the algae. Since household vinegar is only 5 percent acetic acid, it is not strong enough to kill sturdy, mature weeds. Natural sources like volcanoes, forest fires and lightning strikes also add to the man-made pollution. The acetic acid component of vinegar causes burning of a plant's cuticle. SO2 and NOx become acids when they enter the atmosphere and react with water vapor. 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 runs off into lakes, rivers, stream, etc. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation (such as snow). The acid rain also harms plants, it destroys their photosynthesis.Acid rain is when the acid are let out of factory. It also allows acid entrance to the plant system, where it suppresses photosynthesis. Acid rain affected plants and animals are readily attacked by the pathogens and destroy them. In acid medium, plants absorb many of the meals from the soil and bioconcentrate them leading to biomagnifications in the food, chain, which becomes a potential danger for destruction of food chain, tropic levels and finally the ecosystem. When acid rain falls upon an ecosystem, it affects the water supply as well as the plants and animals in that area. Acid rain also damages the waxy outer coating that protects the leaves. In the slightly acidic soils in typical evergreen forests in the Northeastern U.S., Canada, and Europe, two other effects can neutralize the acid rain. In aquatic ecosystems , acid rain … New growth is especially susceptible to acid rain; young rootlets and leaf shoots tend to be the most vulnerable to low pH conditions. The gas rises up into the clouds which when the clouds rain, it kills the animals. The short-term effects alone—cold, darkness, and acid rain—would kill plants and photosynthetic plankton, the base of most food chains. Eutrophication (from Greek eutrophos, "well-nourished"), dystrophication or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae. Acid rain caused by air pollution in China ‘may be causing fatal landslides’, say scientists. Normal rain is slightly acidic, with a pH of 5.6, while acid rain generally has a pH between 4.2 and 4.4. New study suggests pollutants from burning coal could have a role in triggering natural disasters Rotting vegetation and erupting volcanoes release some chemicals that can cause acid rain, but most acid rain is a product of human activities. 11. The acid can be immobilized as the soil or vegetation retains the sulfate and nitrate ions (from sulfuric and nitric acids). 10. Acid rain, also known as acid deposition, is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from power plants, cars and factories.
