Term paper about acid rain

Publicado em Agosto 2017

As acid rains continuously fall on fertile soil, acid depositions containing sulfuric and nitric acid settle and seep in. The greatest manifestation of these acid rain effects in the U. When coal and petroleum are burned in automobiles, electric power plants, and factories, they release certain harmful gases into the air. There is no doubt that acid rain effects have caused the environment great amounts of distress. These are the similar occurrences brought about by acid rain on farm lands used for crop vegetations. In acid-sensitive landscapes, acid deposition can reduce the pH of surface waters and lower biodiversity. K.

In the U. To top Acid rain , also called acid precipitation or acid deposition, precipitation possessing a pH of about 5. The presence of these acidic substances tends to affect the calcium, sodium, magnesium and potassium which are considered as weak elements in the soil. The term acid rain is also applied to other forms of precipitation-snow, hail, sleet, and fog-that are similarly acidic. These prevented scientists and chemists alike to pinpoint the exact causes of crop failure. Acid rain hasn’t just occurred in the last twenty to thirty years. S. , the harsh effects of acid rain on plant growth, became evident in the highly elevated forests of Great Smoky Mountain National Parks and Shenandoah, found in the Appalachian Mountains starting from Maine to Georgia. In recent studies made by scientists from the University of Vermont, the wood cores or rings found in more than a hundred trees of varying species showed that trees began with their growth decline as early as the 1950s. Unfortunately, those in the White Mountains of New term paper about acid rain Hampshire have died. On the other hand, the high elevation of forests brings the plants and trees nearer to the O3 in the atmosphere which is in fact called, ground level ozone layer. Aluminum has been established as having harmful effects to plants because the substance prevents calcium absorption. The phrase acid rain was first used in 1852 by Scottish chemist Robert Angus Smith during his investigation of rainwater chemistry near industrial cities in England and Scotland. Acid rain that contained strong sulfuric and nitric acids has caused numerous forests all over Europe, to die. , to be very acidic. When the water in the air comes down as rain, sleet, hail, or snow, it carries with it these gases. The sulfuric and nitric acid that turned rain water into acid water continued to fill the Earth’s atmosphere as industrialization further heightened the demand for fossil fuel. S. In fact, infrastructures and human health conditions have also shown considerable damages from the accumulated and combined effects of pollution and acid rain. This is known as acid rain. Forest areas particularly in Czech Republic, Slovakia and Switzerland covering as much as 200,000 to 300,000 hectares have died from acid rain effects on trees. Although the problem of acid rain has been significantly reduced in some areas, it remains an important environmental issue within and downwind from major industrial regions worldwide. However, unlike forest soil, which does not receive aid from human intervention, farm lands are treated with soil lime in order to counter the indirect effects of acid rain on the crops. Another possibility is that the combined effects of acid rain with O3 or the bad ozone, formed due to the chemical reaction of nitrogen oxide with Volatile Organic Compound or VOC. This did not come as a surprise at all since the areas were recorded to have received the highest input of acidic precipitations. Acid rain is a form of air pollution. The sulfuric and nitric depositions of rainwater can also cause the aluminum content in rocks to leach and dissolve in soil water. In addition to aluminum, concentrations of sulfuric and nitric acids have accumulated in the soil and are likewise being absorbed by the trees or plants. Article Contributors It was discovered to have increased in acidic content by as much as 100 times over, which gave birth to the term acid rain, referring to the greatly altered atmospheric precipitations. As a global environmental issue, it is frequently overshadowed term paper about acid rain by climate change. Acid rain also occurs in Asia and parts of Africa, South America, and Australia. 2 or below primarily produced from the emission of sulfur dioxide (SO 2) and the constitution essay nitrogen oxides (NO x; the combination of NO and NO 2) from human activities, mostly the combustion of fossil fuels. Rain is one of the most essential ingredients for human and animal life. The phenomenon became an important part of his book Air and Rain: The Beginnings of a Chemical Climatology (1872). Today, decades of term paper about acid rain annual acid depositions from these human activities contributed acidic gases beyond levels of what the Earth could normally handle. These custom papers should be used with proper reference. Although counter measures and regulations against acid rain effects on plants and trees are being implemented, the greater question term paper about acid rain is, how many more trees or even forests will diwali celebration essay die before those measures could result to positive effects? Acid rain - Student Encyclopedia (Ages 11 and up) When fossil fuels such as coal, gasoline, and fuel oils are burned, they emit oxides of sulfur, carbon, and nitrogen into the air (see oxygen). Although rain is naturally acidic, it is being increasingly acidified by pollution from homes, factories, power stations and cars. Acid rain strips arable land of the nutrients needed to sustain the growth and propagation of crops. Yet laboratory results related to studies of the effects of acid rain produced mixed results. As trees are continuously subjected to acid rainfalls, the acid depositions strip the leaves and the needles off of their calcium contents. Industrialization came in research paper linux the wake of several inventions that aimed to make work easier, produce faster and produce more, by burning coal to make the machines work. The term used to describe this problem is “acid rain”. In recent years, UK reported reviews for essay writing services losses estimated at 25milliion UK pounds when large parts of their territory in Scotland and Cimbria were totally destroyed by acid rain. It was gathered that fossil fuels, which could be anything from coal, oil or natural gas came into large term paper about acid rain use during the Industrial Revolution, which began in England in the mid 18 term paper about acid rain th century. He suggested a link between acid rain and SO2 given off when coal was burnt by term paper about acid rain local factories. Acid rain is very damaging to all life forms. However, this process was altered by the presence of acidic substances that influences ions to attach themselves to the clay instead. Are the continuing declines of red spruce trees found in Adirondack Mountains, New York, in Green Mountains of Vermont. The water provided term paper about acid rain by rain allows all life on Earth to survive. The greatest degree of degradation take place in urban areas, where large concentrations of O3 are found. These gases combine with essay written the oxygen and water in the air. As the latter remain in the soil, they evaporate and go back to the atmosphere. In acid-sensitive areas, acid rain also depletes soil of important plant nutrients and buffers, such as calcium and magnesium, and can release aluminum, bound to soil particles and rock, in its toxic dissolved form. Hence, plant and tree roots are unable to absorb and utilize the nutrients for growth and development. Forest trees and plant vegetations cannot survive on land that is barren and devoid of nutrients. It was not until the late 1960s and early divorce arguments essay 1970s, however, that acid rain was recognized as a regional environmental issue affecting large areas of western Europe and eastern North America. The presence of aluminum in soil water, adversely affects the roots' capacity to absorb and distribute nutrients throughout the plant’s or tree’s system. A few theories offered include the premise that some plants and trees have stronger tolerance to acid depositions of sulfuric and nitric acids. The results have been devastating, and it may take several decades more before man can undo all the negative effects of acid rain on plant growth and on other environmental elements. In fact a chemist named Robert Smith found rainfall in Manchester, U. These oxides combine with moisture in the air to form sulfuric acid, carbonic acid, and nitric acid. dmf cover letter They are nutrients than can be easily absorbed by the roots of trees and plants in order to grow and survive. This was over 100 years ago. Acid rain contributes to the corrosion of surfaces exposed to air pollution and is responsible for the deterioration of limestone and marble buildings and monuments. It weakens trees and increases their susceptibility to damage from other stressors, such as drought, extreme cold, and pests.
