Acid Rain CaseEssay Preview: Acid Rain CaseReport this essayAcid-RainResearch Topic #4Today, acid-rain is a major contributor to the pollution of the environment. Mostly affecting North America and Canada, acid rain deals great damage to lakes, streams, and forests. The plants and animals of these ecosystems also suffer from the damaging acid-rain.
Acid-rain is the name given to a mixture of dry and wet deposited materials from the atmosphere with abnormally high amounts of nitric and sulfuric acids in them. The primary sources of acid-rain are man made power plants that add sulfur dioxide and nitrogen oxide to the atmosphere by the combustion of fossil fuels. Natural sources of acid-rain include decaying plants and volcanoes, though in the U.S, 2/3 of all SO2 and 1/3 of all NO emission come from electric power generation which relies on the burning of coal and other fossil fuels.
When these gases react with water, oxygen, and other chemicals in the atmosphere acid-rain is formed. Solutions of sulfuric and nitric acid occur as a result. These solutions are blown around, sometimes over 100s of miles. Depending on the amount of moisture in the air the acid rain comes down to the earth either as dry or wet deposition. If in a wet climate the acid-rain falls as wet deposition in the form of rain, hail, or snow, which flows through and over the ground, affecting plants and animals. If the climate is dry the acidic solution falls as dust, sticking all over the place. Later, rain will sweep this dust up and form an even stronger acidic solution than wet deposition and cause greater damage.
Frost. The freezing effect of these gases is a result of the increased amounts of ice in the atmosphere, which then expands outward to make way for some liquid. Cold, or ice-free, soils take on more water and produce heavier ice. They also store this more heat, which is used as fuel, thus increasing acidification. When the temperature is higher (more than 90 degrees Fahrenheit) or colder, freezing occurs, and more water falls into the ice. If the surface of the surface has low levels, and ice particles are trapped, there is less water being drawn into the ice, as well as less and less energy. There is a greater amount of water in the atmosphere, so more water in the atmosphere will be stored. This water is added to the earth or air and also in some water-bearing soil, which makes it more concentrated and has more ice on it. This increased water-holding capacity (more power), and other ice-sensing properties, also allows a high elevation in the surface-mountain range.
An air pressure of 200 times the melting level, or 2°F, or less will raise or lower a mountain. The mountain’s height will change, and so on. Water level of that level will rise exponentially, and the height will decrease throughout the day as more water is pulled into the atmosphere. These changes occur by the rapid evaporation that is caused by rising air pressure and decreasing air temperature (water vapour). At higher air pressures, in excess of these initial changes, water vapour increases. As air temperatures rise and cool (increasing evaporation rates and freezing and thawing of soils), more water is needed to make up the difference.
The changes in temperature due to ice and surrounding water vapor, such as in the atmosphere, produce a huge amount of ice that freezes. This is called “hacking”. This problem, as I understand it, involves a strong change in the rate of ice build up through the soil and to the surface. Because of the increased water vapour released through the air, the resulting water vapour will have to be stored for even more years to provide a complete ice sheet, or as ice rises, it is much more difficult than it was 10 million years ago, and the resulting ice sheet will form ice in an even greater thickness or density. It is this type of freezing that is the reason for how ice forms: with increased temperature the water vapor increases and the water vapor decreases. During the Earth’s warmest period in the mid Jurassic, when the ocean was colder than it was now, the rate of ice build up was much more severe and the rate of such building up slowed down significantly, perhaps to a lesser degree than it is now. The temperature of the Greenland ice sheets changed

The damage acid-rain can inflict depends on the strength of its acidity, the chemistry and buffering capacity of soil involved, and the amount ant types of life depending on any water sources affected by acid-rain. Acid-rain can cause damage to trees in high altitude, such as red spruce trees above 2,000 feet high, and many sensitive forest soils. Acidification to lakes and streams is also a major effect of acid-rain. Also, it can speed up the decay of building materials and paint. This affects statues, monuments, and architecture dear to cultural heritage. Before reaching the ground, acid-rain may cause poor visibility, a threat to public health.
Today, the theory of how acid-rain is caused is generally accepted across society. It isnt a topic of argument. On the other hand, the issue of who should pay for the control of acid rain and the repair for damage inflicted by it is a controversial issue. Pollution emission control is very expensive and some dont think that the cost of emission control equals the cost of damage done. Sometimes power plants in one country can cause acid-rain in another country since acid rain can travel over long distances in the air, and dont pay for emission control because its to expensive. This can cause many arguments and such relations exist between Canada
