    What is Acid Rain? Acid rain is rainfall that has been acidified. Rain is acidified by oxides of sulfur and nitrogen. Acid rain usually has a pH of less than 5.6. II. What damage does it do? There are many damages and effects caused by acid rain. Acid rain can cause buildings, statues and bridges to deteriorate faster than usual. Another problem is it harms thousands of lakes, rivers, and streams worldwide. It disrupts lake ecosystems and kills wildlife in affected lakes, rivers and streams. Acid rain also damages soil and the tree roots in it. When soil is acidified, tree roots are damaged making them not able to draw in enough nutrients. III. What causes it? Acid rain can be caused by many things. Industrial emissions from factories and power plants that burn fuels such as natural gas, coal or oil, emit smoke that gives off oxides of sulfur and nitrogen is one cause. Another cause is vehicles (e.g. cars, buses) that burn gasoline and diesel. IV. How does it form? Acid rain is formed when pollutants called oxides of sulfur and nitrogen, contained in power plant smoke, factory smoke, and car exhaust, react with the moisture in the atmosphere. Dry deposition, such as soot and ash, sleet, hail, snow, smog and low level ozone are forms that acid rain can take, despite its name. V. What can we done to reduce its damaging effect? There are many possible solutions to the acid rain problem and we will mention some of them. One is to use fuels that burn more cleanly. Another solution is to burn coal more efficiently. Power plant and factory chimneys can be fitted with scrubbers that release 90-95% sulfur free smoke and also produce sludge from which gypsum, a building material, can be produced.

    rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.

    Acid rain is a form of precipitation that is acidic, in the acid rain there’re high levels of Hydrogen ions. This phenomenon can damage all the living and not living things in the Earth such as: biotic and abiotic mass; the buildings, vehicles, stores, banks, etc. The acid rain is caused by the mix of dangerous gases in the air when reacting with water. The emissions of these gases come from big industries. However, they form as well from volcanic eruptions and we can find for example: nitrogen oxide in the lightning strikes. The outcomes of the acid rain are harmful for people, animals, plants and all the things we have in the environment, as we know acids are corrosive and they can break down the surface of objects and if we expose to this rain we can get serious injuries in the skin. That’s why it is important to take care of the environment with our actions, so we can prevent this phenomenon. By reducing the emission of gases like sulfur dioxide and nitrogen oxide it can make a big difference.

    ( Acid Rain assignment ) Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions. The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and erosion of stone statues. The principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes. Thus, for example, fumaroles from the Laguna Caliente crater of Poás Volcano create extremely high amounts of acid rain and fog, with acidity as high as a pH of 2, clearing an area of any vegetation and frequently causing irritation to the eyes and lungs of inhabitants in nearby settlements.[25] Acid-producing gasses are also created by biological processes that occur on the land, in wetlands, and in the oceans. The major biological source of sulfur containing compounds is dimethyl sulfide. Nitric acid in rainwater is an important source of fixed nitrogen for plant life, and is also produced by electrical activity in the atmosphere such as lightning. Acidic deposits have been detected in glacial ice thousands of years old in remote parts of the globe.[13] Soils of coniferous forests are naturally very acidic due to the shedding of needles, and the results of this phenomenon should not be confused with acid rain. Human activity The coal-fired Gavin Power Plant in Cheshire, Ohio The principal cause of acid rain is sulfur and nitrogen compounds from human sources, such as electricity generation, factories, and motor vehicles. Electrical power complexes utilising coal are among the greatest contributors to gaseous pollutions that are responsible for acidic rain. The gases can be carried hundreds of kilometers in the atmosphere before they are converted to acids and deposited. In the past, factories had short funnels to let out smoke but this caused many problems locally; thus, factories now have taller smoke funnels. However, dispersal from these taller stacks causes pollutants to be carried farther, causing widespread ecological damage.

    Acid rain is a form of precipitation that is quite acidic, so it has high levels of hydrogen ions. As it is an acid it is corrosive which means it can harm the environment. Acid rain is a reaction of sulphur dioxide and nitrogen oxide that react with water molecules producing acids. If the output of sulphur dioxide and nitrogren oxide can be lowered then there is less acid rain. This would result in less damage to the environment, such as metal corrosion, buildings that weather, paint that peels, wood that rots, soil that does not promote healthy growth of plants etc

    Acid Rain, Normal rain is slightly acidic in nature. however, for any reasons if the rain water dissolves the acidic gases resulting in the precipitation of highly acidic. This kind of acidic precipitation is called as acid rain. What damage does it do? The acidic precipitation causes dissolving and washing away of essential nutrients causing stunted growth of plants. It also releases toxic elements like aluminium in the soil. The acidic precipitation disturbs the normal pH of water bodies affecting the aquatic flora and fauna. What causes it? The main gases responsible for acidic precipitation are sulphur dioxide and nitrogen oxides. how does it form? The industries releases sulphur dioxide and nitrogen oxides into the air. These gases mix and interact with the water vapour at high alititudes resulting in acidic precipitation. What can be done to reduce its damaging effects? The dependence on fossil fuels should be reduced to curtail the formation of acid rain. A shift to alternate renewable energy resources is suggested.

    Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition, which can appear in many forms. Wet deposition is rain, sleet, snow, or fog that has become more acidic than normal. Dry deposition is another form of acid deposition, and this is when gases and dust particles become acidic. Both wet and dry deposition can be carried by the wind, sometimes for very long distances. Acid deposition in wet and dry forms falls on buildings, cars, and trees and can make lakes acidic. Acid deposition in dry form can be inhaled by people and can cause health problems in some people.
