    Acid Rain Acid rain is a serious problem with disastrous effects. Each day this serious problem increases. Many people believe that this issue is too small to deal with right now, and others believe it should be met head on. In the following paragraphs I will be discussing the impact of acid rain effects on wildlife and how our atmosphere is being destroyed. Causes Acid rain is a cancer, eating into the face of Eastern Canada and the North Eastern United States. In Canada, the main sulphuric acid sources are non-ferrous smelters and power generation. On both sides of the border, automobiles are the main sources for nitric acid (about 40% of the total). Power generating plants, industrial com ...

  • Acid Precipitation - 663 words
    Acid Precipitation Acid Precipitation Our atmosphere functions as living ecosystem of chemical reactions. Through the help of the water cycle, chemicals pass through the atmosphere and are eventually taken up by the soil, surface water, or organic materials. Human beings have added enormously to the atmospheric burden of many toxic substances. The most prominent evidence of this is the presence of acid rain: precipitation and particles that have been made acidic by air pollution. Acid rain is a direct consequence of the atmosphere's self-cleansing process. The tiny droplets of water that make up clouds continuously capture suspended particles and soluble trace gases. Not all trace gases can ...

    Acid Rain Acid Rain (The Environmental Effects) My first question is , What is Acid Rain? You hear about it all the time in the news and it is very important to the earths ecosystem. In simple terms, acid rain is rain that is more acidic than normal. All objects in nature have a certain level of acicicity but acid rain has too much acid in it. Acid rain is a complicated problem, caused by air pollution. Acid rain's spread and damage involves weather, chemistry, soil, and the life cycles of plants and animals on the land and from acid rain in the water. Acidity is measured using a pH scale, with the number 7 being neutral. Therefore, a body with a pH value of less than 7 is acidic. On the oth ...

Osmoregulation is the process of maintaining the delicate balance of salts and minerals in their tissues. For freshwater fish, maintaining osmoregulation is key in their survival. Acid molecules, which are a result of acid rain in the water, cause mucus to form in the fishs gills. This in return prevents the fish from absorbing oxygen. If the fish are unable to absorb oxygen, the consequence could be the eventual suffocation of fish and the low pH could throw off the balance of salts in the fish tissu ...

    Acid Rain Acid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone ( SO, NOx, and O ) is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren't absorbed into clouds, they can drift for miles and fall to the ground, resulting in Acid Deposition, or dry deposition. When Acid Rain falls into water it is mixed in with the normal water and causes the pH of the entire body to be raised. Measurments on the pH ( potential Hydrogen ) scale, rise exponentialy, thus, a lake with a pH of 4 is ten times as acidic as a lake with a pH of 5, and a lake with a pH ...

    Acid Rain For years ever since most of the world has been industrialized, the effects of pollution have plagued nations alike. Acid rain is one of the largest contributors to this industrialized form of pollution. Throughout this report an explanation of the devastating effects to the environment caused by acid rain will be given along with what is being done to stop it. Acid rain is made when pollutants arise from the use of coal in the production of electricity, from base- metal smelting and from fuel combustion in vehicles. Once the sulfur and nitrogen oxides from these man made causes are released into the air they are caught by wind currents and are blown hundreds of miles away. The gas ...

    Acid Rain What is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by the pH of pure water in reaction with atmospheric concentrations of carbon dioxide, resulting in carbonic acid. These particles partly dissociate to produce hydrogen ions and bicarbonate ions ...

  • Acid Rain - 312 words
    Acid Rain Acid Rain Acid rain forms high in the clouds in a gaseous form. Theses gasses stay in the atmosphere until they come in contact with rain that dissolves the gasses. A mild solution of sulfuric and nitric acid is formed. These drops fall to the earth and get into our water table beneath the surface. From there they are collected into streams, rivers, and lakes that eventually will lead to the ocean. Rain isn't the only form acidity falls to the earth. About half of all the acidity falls back through dry deposition as gasses and dry particles. The wind blows the acid particles onto cars, homes, trees, and buildings. The acid discharge is then washed from the surfaces by rain. The run ...

  • Acid Rain - 1,731 words
    Acid Rain Introduction: What Causes Acid Rain? One of the main causes of acid rain is sulfur dioxide. Natural sources, which emit this gas, are Volcanoes, sea spray, rotting vegetation and plankton. However, the burning of fossil fuels, such as Coal and oil, are largely to be blamed for approximately half of the emissions of this gas in the world. When sulfur dioxide reaches the atmosphere, it oxidizes to first form a sulfate ion. It then Becomes sulfuric acid as it joins with hydrogen atoms in the air and falls back down to earth. Oxidation occurs the most in clouds and especially in heavily polluted air where other compounds such as ammonia and ozone help to catalyze the reaction, changing ...

  • Acid Rain And North America - 1,891 words
    Acid Rain And North America In the past century, one of the greatest threats to North America's aquatic ecosystem has been the widespread acidification of hundreds of thousands of waterways. Acid rain has effected plant and animal life within aquatic ecosystems, as well as microbiologic activity by affecting the rates of decomposition and the accumulation of organic matter. What causes this poisonous rain, and what can be done to improve North America's water quality and prevent future catastrophes? To answer these questions, we must first examine the cause and formation of acid rain, as well as understand ways to decrease or prevent its formation. Formation of acid rain. Acid deposition, mo ...

  • Acid Rain Legislation - 824 words
    Acid Rain Legislation Acid Rain Legislation Acid rain is a destructive force as a result of nature and man colliding. It is formed through harmful industrial emissions combining with contents of the earth's atmosphere; a dangerous combination. This prompted governments throughout North America to take action. Many laws and regulations have been implemented, yet the question still remains, Should tougher legislation be implemented to force industries to reduce acid rain emissions? To decide whether tougher legislation should be implemented, one must first understand the details of what exactly acid rain is. Acid rain is a result of mankind's carelessness. It travels a long one of the most eff ...

  • Acid Rains - 540 words
    Acid Rains Acid rain refers to all types of precipitation--rain, snow, sleet, hail, fog--that is acidic in nature. Acidic means that these forms of water have a pH lower than the 5.6 average of rainwater. Acid rain kills aquatic life, trees, crops and other vegetation, damages buildings and monuments, corrodes copper and lead piping, damages such man-made things as automobiles, reduces soil fertility and can cause toxic metals to leach into underground drinking water sources. Rain is naturally acidic because carbon dioxide, found normally in the earth's atmosphere, reacts with water to form carbonic acid. While "pure" rain's acidity is pH 5.6-5.7, actual pH readings vary from place to place ...

  • Agricultural Problems Facing The African Nations - 620 words
    Agricultural Problems Facing The African Nations Agricultural Problems facing the African Nations Africa is a nation hit by many agricultural problems. As a majority, Africa is a desert type climate. Rainfall is heavy and quick, leaving soil deeply engraved by the pounding of the rain. It falls for such a short period of time, not allowing the ground to soak up the moisture before it is evaporated into the air because of the heat. Droughts attack the nations often never providing enough food to sustain the rising population of the nations. African families are growing bigger and bigger by the year. One in every seven children is going to die before school age. That means that the nation is u ...

    Air Pollution Acid rain is a problem that has plagued earth for years. It is poisoning our waters, animals, plants, soil, and more. It is a problem that can not be ignored or it might have catastrophic results on our environment. Acid rain is caused by air pollution, which is due to man-made actions. Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Power plants and factories burn coal and oil, which is used to produce the electricity we need to heat and light our homes and to run our electric appliances. We also burn natural gas, coal, and oil to heat our homes, and our cars, trucks, boats, and airplanes use gasoline to run, whic ...

  • American Impressionism - 954 words
    American Impressionism In the years following the Civil War, American art underwent a fundamental shift. The traditional Romantic style of painting, which focused on portraying majestic scenes in stark, vivid lines and shapes, gave way to a new concern for light and atmosphere. It was the age of Impressionism. Impressionism was not indigenous to America. In fact, its origins lay in France, which had long been at the fore of artistic innovation. The French Impressionists threw off the shackles of traditional painting in favor of an airier, lighter style. The purpose of Impressionism was to convey the impression of an object by capturing the patterns of light and color on and surrounding it. T ...

  • American Indians - 929 words
    American Indians Indians in eastern North America possessed no alcohol at the beginning of the colonial period. By 1800, so much alcohol flowed through the Indian villages east of the Mississippi that each community were forced to decide to take it or not and they made a tragic choice by taking it because it destroyed their cultural. The Indians who drank did so to the point of intoxication enjoyed the experience they got from it. If Indians chose to drink out of frustration and despair, they were not alone; as social scientists have made clear, whenever Western societies undergo periods of rapid transition, rates of drinking increase. Documentary evidence also suggests that some Indians enj ...
