Abstract
In this paper the author describes a science project in which she attempted to see if antacids had an affect on acid, in particular, acid in soil. In the research, the author hypothesizes, before conducting her experiment, that the antacid will decrease the acidity of the soil. After conducting her experiment, the author concludes that the data collected supports her hypothesis.
From the Paper
"The immediate purpose for this experiment was to determine the relationship between antacids and acidity in soil. As discussed in the discussion, I believe that the antacids would have an affect on the acidity mainly because antacids are neutralizers. The data that I collected did support my hypothesis. Although the data may have inadequacies because of the sources of error, it shows that the acidity of the soil did decrease in response to adding the antacids into the soil. The reason why I believe that the data is inaccurate in some parts is because after adding 35 g of antacids, the results turned back towards the acidic end of the pH scale. It wasn't until adding the 50 g of antacid that the results skyrocketed toward the base end of the scale."

From the Paper
"What do acids and alkaline truly have in common? The history of the understanding of an acid is relatively old. Dating back to the Roman Empire days, came the word that we derived acid from, acidus, meaning sour. Around the 1800s, French chemists erroneously believed that all acids contained oxygen, including the famed Antoine Lavoisier. Svante Arrhenius, a Swedish scientist in the mid 1800s and a Nobel laureate, did a few experimentations with acids, and came up with concocting a definitive, chemically sound definition of an acid. Later on, in the 20th century, the partners Bronsted and Lowry initiated theories about acids using and published the acid-based concept. The most pragmatic research of acids and bases came from the American chemist Gilbert Lewis. Ever since then, the idea of acids and base has been widely recognized, although the definitions of such terms have been rather controversial."

Abstract
In this essay, the writer points out that soil bacteria control the course of nitrogen, carbon, and phosphorus through ecosystems. Soil samples were taken from established sites, which have undergone existing long-term manipulations of temperature, nutrient and light availability. The writer discusses that the soil samples were found to contain bacteria through testing and are being studied to determine whether treatments known to affect plant communities also affect soil microbial biomass, activity, gene expression, and community composition as measured by terminal restriction fragment length polymorphisms.
From the Paper
"Soil is an intricate and active biological system, and at times it is difficult to determine the composition of microbial communities in soil. Yet, the study requires a wide variety of methods, which includes methods of extracting DNA from soil suitable for PCR amplification to monitor GM rhizobia and extracting mRNA directly from soil to use in gene expression studies. Hydrocarbons seem to be a contaminated factor when isolating the soil samples in determining bacteria characterization. "Bacteria were isolated from contaminated soil with the media indicating several homolog similarities (researched the possibility of several bacteria names through DP database as determined by the program SIMILARITY_RANK (10)"."

Abstract
This paper explores how acid rain is produced, what its impact is on the environment, what has been done by government agencies to help the problem, how effective these measures have been, what individuals can do to help reduce this problem, what are the current technologies for reducing emissions and how these technologies can be used to reduce acid rain in the future. It demonstrates that current attempts to reduce emissions from power plants will not have a significant effect on acid rain reduction; and will support the idea that there is not a single solution to the problem of acid rain, but rather a combination of technologies and methods will have to be utilized to have a noticeable effect of the reduction of and repair of environmental destruction caused by acid rain.

From the paper:
"Our modern world has many conveniences. We enjoy hot water, lights, computers, cars, and many other conveniences, which are now an integral part of our society. Many of us cannot imagine life without them. We seldom think about the costs every time we turn on a light. We do not think about the where the electricity is produced and what the effects on the environment might be. We simply turn on the light. As with all good things, there is a cost. One cost of our modern conveniences is acid rain caused by the burning of fossil fuels. The effects of acid rain came into the forefront during the early seventies as its effects began to be noticed on a global level. The impact of the effects of acid rain is considered to be of great concern to some and of little concern to others. No matter which side you are on, we all must agree that energy consumption will continue to increase globally and we must be weary of the effects of energy production and always stay focused on future generations."

Abstract
The following paper examines why environmental scientists are concerned that the level of acidity in rain and snow has increased beyond its normal levels in the United States. The writer discusses the ways in which this has had a serious impact in several areas, including forests in the northeast and many of the country's most valued monuments.
From the Paper
"Munton (1998) expresses the same concerns. He notes that emissions have already been reduced by 50%. That is an impressive improvement, but perhaps still more than delicate ecosystems can stand. He suggests that we may need even more restrictive interventions in place, and points out that modern society?s effects on the atmosphere goes beyond acid rain, which may also affect human health, but to breathable particulates, effects on the ozone layer, and regional haze making particular areas periodically more vulnerable to the effects of airborne pollutants.
"In conclusion, it may be too soon to be satisfied with our efforts so far. Given the tremendous amount of pollution released into the air, a 50% reduction may be a result that looks good on paper but that is still significantly damaging to our environment."

From the Paper
"Air pollution is a well-recognized environmental problem throughout the world. Studies have shown, time and time again, that the environmental and health-based impacts of air pollution are both detrimental and undeniable. One of the most important forms of air pollution for our society as a whole to recognize and deal with in an expedient manner is acid precipitation. Because of the very nature of this type of air pollution, the direct and indirect effects of acid precipitation are both far-reaching and difficult to get under control. Understanding more about the causes, effects, and implications of acid precipitation and its impacts on our daily lives is the first step that we all need to take in adopting a more proactive approach to solving this problem."

Abstract
Soil has long been deemed important by agricultural concerns, however, it was only within the last 150 years that rail travel and, later, large-scale civic works made the study of soil important to civil engineers. The paper shows that the sub-study of civil engineering that is dedicated to the study of soil is more commonly known as soil mechanics. This field is used to assess the soil topography of land before major public or private construction projections are created.
From the Paper
"The five main types of soil particles that are encountered by civil engineers include (in order of particle size) boulders, gravel, sand, silt cohesive, and clay. Boulders are the largest elements in soil and usually present a problem to civil engineers, but may be used in a place where the soil is otherwise soft to form a foundation upon which to build a road or other civic work. Historically, boulders were used for this purpose before it was cost-effective to introduce other materials. There are cost efficiencies in the use of boulders: they can often be found where bedrock is not near the surface of the earth, such as in the great lakes region where they were deposited during the last ice age."

Abstract
Never before in the history of mankind have we faced an environmental dilemma with the worldwide effects of soil erosion. The problem is so severe, that many experts fear the land will not be able to produce enough food to feed the world's population in the next century. The paper discusses the problem as two fold - marginal land and deforestation. Much of the world's land is marginal sandy desert and sub-desert. In order to feed and house their growing populations many countries in South America, Asia, and Africa clear the world's forests to create more grazing land. The paper shows that, although much of this land has rich soil, the effect of deforestation is an increase in soil erosion. Once the trees are removed, the soil erodes and soon becomes marginal. Combined this with the problem of acid rain, other forms of pollution, and over population, and it is obvious we are entering a time of intense food scarcity.
From the Paper
"In order to preserve life for future generations, we must preserve the soil. Conservation and research are the keys to the future. Conservation and improving soil quality will prevent food shortages in the future. The quality of food today has decreased to dangerously low levels. In spite of increased knowledge about nutrition and advancements in medicine, people today are not as healthy as previous generations. We suffer from nutrient deficiencies related to the poor quality of soil."

Abstract
This well-researched and detailed paper explores the effects of acidic precipitation (acid rain) which has been a major factor in fish kills throughout countries in the northern hemisphere. The writer of this paper cites numerous studies which have linked aluminum toxicity along with acid rain as the main cause of fish extinction. This paper stresses the urgency in developing a successful management tool in determining the viability of fish populations in various natural settings. This paper also contains detailed information and results of various case studies as well as two graphs that support the author's claims in this report.
From the Paper
"The fish used in this experiment were obtained from a trout farm which ensures the relative similarity of the fishes used in the experiment. They were acclimated to artificial soft water for 2 weeks before they were used in the experiment. They were then transferred to flux chambers for the experiment and given 24 to 48 hours to recover from the handling stress before they were exposed for 24 hours to low-pH water (pH 4.4, 4.8, or 5.2) A control group (N=36) for each of these pHs was left in these conditions for 10 days. The experimental group after this 24 hour exposure to low pH levels were exposed to concentrations of Al of 111, 333, or 1000 ug/L at the same pH (N=72)."

Conclusion
From the Paper
"The harm that acid rain does can be measured tangibly with scientific testing but it also has an intangible impact on the atmosphere as it causes changes to the way things look and feel as well. The beauty of plants and forests and streams can be negatively affected through the damage that acid rain leaves behind (Understanding acid rain http://weather.about.com/library/weekly/aa032502a.htm)."
"One of the more specific issues with acid rains is its ability to cause the acidification of lakes and streams worldwide. It is also causing damage to trees, especially the trees that are found at higher elevations. One example of this is the red spruce trees that are normally located at 2,000 feet above sea level (Effects of Acid Rain http://www.epa.gov/acidrain/effects/index.html)."

Abstract
This work researches and examines why many Ohio soils have significantly more clay in the subsoil than in their surface horizons or the soil parent material. The author argues that these changes are due to man's agricultural pursuits in the area. The paper also explores the soil in terms of Ohio's climate and the soil's organic composition.
From the Paper
"Soil organic matter is the source of nitrogen, phosphorus and other micronutrients needed in crop production and which is formed during the oxidization and decay processes that occur in the soil. The levels of these nutrients produced by the soil processes is difficult to change. According to the work entitled: " " published in the Agronomy Bulletin: "Historically, when forages were part of the crop rotation, nutrient release and soil tilth increased due to the season-long production of roots. Currently, well fertilized, high-yielding grain crops return large volumes of residue to the soil and are a source of nutrients. On medium-textured soils low in organic matter, crop residues are usually more beneficial when left on the surface than when incorporated. During the growing season this surface residue reduces the formation of soil crusts and results in increased water infiltration and higher crop yields. Crop residue on the surface of fine-textured soils such as silty clay loam or clay loam may delay planting by delaying soil drying." (Ohio Agronomy Guide, 14th Edition; accessed online 2006-04-08)"

Abstract
This paper provides a definition of "acid rain" and how it is formed. It looks at the dangers of acid rain and the damage it is doing to the environment. It briefly examines options and programs that can be performed to reduce acid rain.
From the Paper
"The term ?acid rain? is a little misleading. Rain is naturally acidic, from both carbon dioxide in the air and absorption of chlorine from the ocean (Gordon, 2002). All compounds can be measured for acidity or alkalinity on a Ph scale ranging from 0 ? 14, with anything below 7 showing at least slight acidity. Rain is judged ?acid? when its Ph falls below 5. (Gordon, 2002) Environmental scientists are concerned because in some parts of our country, the level of acidity in rain and snow has increased beyond its normal levels. This has had a serious impact in several areas, including our forests in the northeast and many of our most valued monuments."

Abstract
Soil is an incredibly important resource and maintaining the fertility of our soils is a pressing issue at the forefront of environmental science as we try to feed an expanding global population. Queensland, Australia is one area of the world where soil is being depleted and degraded at an alarming rate. Through an examination of this specific resource management problem, this essay analyzes the concept of impact assessment to develop fair, efficient and effective solutions to this environmental problem.
From the Paper
?The preservation and conservation of the worlds soil is a serious resource management problem. The sustainable use of our soil will be a major challenge for the human species for many years to come. When assessing the impact of any resource management problem and developing feasible solutions to that problem certain factors must be taken into consideration. Examining the fairness, efficiency and effectiveness of a proposed solution is paramount to its potential success. A solution for soil loss that is completely unfair to farmers or ranchers will be rigorously opposed and impossible to implement.?

Abstract
This paper introduces, discusses, and analyzes the topic of acid rain. Specifically, it defines acid rain and discusses its effect on the environment.
From the Paper
"The term "acid rain" is really a bit of a misnomer, because acid "rain" can be either wet or dry, and is a global term that covers almost any type of acid that falls from the atmosphere onto the Earth (EPA). Acid rain is often called "acid deposition" by scientists, but the common term most of the public understands is acid rain. Acid rain is a mixture of sulfur dioxide and nitrogen oxides, which result from burning fossil fuels like coal and oil. These chemicals react as they are released into the atmosphere, and join to create a mild solution of acidic compounds that becomes acid rain when it falls to the ground mixed with precipitation, such as rain, fog, and snow, or falls to the ground on its own if there is enough of it in the air. Acid rain is common all over the world, and as our reliance on fossil fuels grows, so does the potential for increasing acid rain."
