Abstract
The paper describes the natural phenomenon of volcanoes and the severe outcomes that can result from a volcanic eruption. The paper describes volcanic eruptions in the past and looks at how scientists have improved the methods and abilities of protecting people. The paper relates that in most cases, scientists can predict when an eruption may occur and the best protection seems to be early warning.

Introduction
History and Significance of the Problem
Discussion
Conclusion
From the Paper
"Volcanic gases are released in the air and through the soil as a result of the Magma which is composed of dissolved gases. The most common gases that are released are water vapor, carbon dioxide and sulfur dioxide. In addition to these gases, volcanoes also release smaller amounts of hydrogen sulfide, carbon monoxide, helium, hydrogen, hydrogen chloride and hydrogen fluoride. The survey explains that of the aforementioned gases the most harmful tend to be are sulfur dioxide, carbon dioxide, and hydrogen fluoride."

Abstract
This paper describes a tornado that ripped through Gallatin, Tennessee. The paper portrays how the tornado ripped through Gallatin and made national news for its damage and devastation, including the deaths of 12 residents. The paper is written as if the author of this paper witnessed the event first hand.
From the Paper
"The morning had called for storms. Residents in Middle Tennessee were used to storms, in fact some joked that the Tornado Alley had recently moved to include that region. For several years there had been storms in which Doppler Radar had detected tornadoes in the sky and issued alerts for the area, however, they rarely if ever touched down. Perhaps the worst that happened was a tail whipped out of the sky and damaged a few roofs before retreating back into the clouds. On April 7, 2006 however, the world of those who lived in Gallatin was forever changed, when a tornado not only touched down, but waltzed across the city as if competing in a final dance competition. When it was finally over, people were dead, businesses were destroyed, a college was leveled and homes were completely demolished."

Abstract
In this essay, the writer notes that the Hurricane Katrina disaster will be discussed and debated for years, perhaps for a hundred years and more; and it can safely be assumed that an important part of the discussion will embrace the concepts of race and class. The writer maintains that one can easily imagine a sociology professor in the year 2025 pointing out that had a storm of such colossal intensity been approaching a city of mostly white, middle class and wealthy citizens, a different set of preparations and a wholly different outcome could be expected. This paper reviews and analyzes the social realities of New Orleans before and after Katrina's wrath, from several perspectives, including the theories of Karl Marx.
Outline:
Karl Marx
Katrina
From the Paper
"When considering the fact that the Army Corps of Engineers reported years ago that the levees around New Orleans - much of which is below sea level - were not structurally safe, one has to also consider the class issues within the political structure of the United States; in other words, is New Orleans a place that would have a high priority in the ruling class of Washington D.C.? The answer is no. And so, the Army Corps of Engineers would be (and was) more committed to working on the Florida Everglades' multi-billion dollar project (the president's brother being the governor of Florida) than retrofitting the levees in a city that traditionally votes Democratic, and is largely African American. These points are raised because Marx doesn't specifically talk a lot about "race" per se, but he does make it clear that class struggles have to do with issues that in the case of New Orleans, are largely ethnic."

Abstract
This paper reviews, discusses and analyzes the effect that chemical fertilizer has on the aquatic life in the water surrounding the areas that have been treated by such fertilizers. The paper provides an overview of water systems and how they function, followed by a discussion of the different types of chemical fertilizers in use today.
Outline:
Introduction
Review and Discussion
Conclusion
From the Paper
"The quality of water systems is determined by the degree to which bodies of water are able to support aquatic life while also meeting standards for the protection of human health and the preservation of human life; this level of contamination is determined by establishing baseline standards to measure the periodic relative quality of each individual water system against these original standards (Henning & Mangun 251). Attempts to either maintain or restore the quality of the water in these systems are developed according to the amounts and kinds of material that are emptied into the waterways; the quality of water in streams, rivers, lakes and oceans therefore depends on the capacity of each of these water systems to clean themselves of the various pollutants. According to Henning and Mangun, this ability depends on the types and amounts of the pollutants as well as with water temperatures, rate of water flow, degree of sedimentation, and mineral content (251). The mineral content of pollutants containing chemical fertilizers already account for the lion's share of the nitrogen being released into the world's water systems, but there are other elements involved in modern chemical fertilizers as well, and these are discussed further below."

Abstract
This paper reviews and discusses marine pollution. According to the paper, the ocean plays a critical role in sustaining life on this planet. The paper discusses how economic and social prosperity will be useless if the coastal and marine environments are sacrificed, abused or neglected in the process of development. The paper goes on to discuss the serious environmental issues pertaining to marine pollution facing us today.
From the Paper
"The accidental wreck of a 20-tanker, 987-foot ship of Exxon Valdez in Bligh Reef led to the rupturing of eight of its 11 cargo tanks and the spilling of 10.8 million gallons of crude oil into Prince William Sound in March 1989 (US Congress 1960). Although no lives were lost, the accident was an immense disaster to fisheries, subsistence livelihoods, tourism and wildlife. Most important was the awareness that the sanctity of the Alaskan waters was most outrageously ravaged. In response, US Congress passed the Oil Pollution Act of 1990, which established measures in preparing for and preventing spills for the implementation and enforcement of the US Coast Guard. It requires transporters of oil and production facilities to develop and implement response plans, participate in preparedness drills and maintain safe shipping and handling practices (Earle 1995). MARPOL began to control the operations and passage of new oil tankers, the carrying of noxious liquids in bulk, the control of sewage and other "grey water" and garbage, including plastics, metal, glass, galley wastes and other materials (Earle, US Congress)."

Disaster Management and Volcanoes, 2007.
A discussion of disaster management in the event of volcanic activity.
979 words (approx. 3.9 pages), 3 sources, APA, $ 34.95
»
Click here to show/hide summary
Abstract
This paper explores both past and current methods of disaster management when volcanic activity occurs. The paper focuses on monitoring and detection as approaches to handling potentially disastrous situations. Various methods of detection are explained, such as seismic monitoring. The author concludes that new methods offer hope for better predictions of volcanic activity, yet more must be done for disaster preparation. This is imperative in order to better predict volcanic events and save the lives of those who witness such a natural disaster.
From the Paper
"Seismic monitoring is one of the most common ways to keep track of volcanic activity (Choi, 2004; Mileti, 1999). Seismometers monitor earth movement, including the earthquakes and tremors that sometimes indicate volcanic activity like underground magma movement (Choi, 2004). Though seismic activity is often linked to volcanic events successfully, not all seismic events indicate a coming eruption (Kerr, 2003). For this reason, seismometer readings do not always provide accurate predictions (Choi, 2004)."

Satellites and Deforestation, 2007.
This paper explores how satellite imagery has affected deforestation in the Amazon.
2,135 words (approx. 8.5 pages), 9 sources, MLA, $ 66.95
»
Click here to show/hide summary
Abstract
The paper relates that satellite imagery has affected the deforestation of the Amazon by detecting problems such as road building, mining operations, fires where land is being cleared for crops, logging operations, dam projects and clearing for building projects. The results of these satellite images also indicate rising heat indexes, less forest and damage to the ecological system that exists in the Amazon. The paper reveals how satellites determine data and offers general information about the technology.
Outline:
How Satellites Determine Data
What Satellite Imagery Tells Scientists About the Amazon
How Satellite Imagery Affects the Rainforest
The Types of Satellites Used and General Information About the Technology
From the Paper
"The amount of water or ice particles in the air can be measured by a satellite sensor and this determines part of the information that will tell what is going on, back on earth. Together with satellite visual imagery, the information can give a scientist an amazing amount of information. An article in Satellite Data Applications: Weather and Climate talks about how satellites may measure the physically based parameterization of cloud processes and cloud water. (Weng 407) These measurements are used in a SSMI/Cloud Liquid Water algorithm to find out how the clouds are affected by the thermal emission. (Earth 2005)"

"Extinction"--A Book Review, 2007.
A review of Douglas H. Erwin's book "Extinction."

Abstract
This paper reviews Douglas H. Erwin's book "Extinction," which addresses one of several mass extinctions that have been found in the history of life on earth. The author describes the books format, as well as some of Erwin's theories behind the end-Permian mass extinction. The reviewer concludes by describing how Erwin's book can be applied to today's climatic changes. The book can thus be a warning as well as an informative discussion of the past.
From the Paper
"The author also begins by considering some of the other mass extinctions that took place at a much earlier date, in part to see what caused those extinctions in order to see if the same causes applied to the Permian extinction. The evidence from the extinction at the K-T boundary (between the Cretaceous and the Triassic) has been much analyzed because of the discovery of higher deposits of iridium from that period. Iridium is found primarily in meteors or in some volcanic explosions, and so the higher levels have caused many to see the extinction of the dinosaurs as caused by a large meteor crashing into the earth and depositing iridium around the world on the same geologic level. Another substance found at the site of extinctions has been fullerenes, which can be produced by lightning strikes, forest fires, and meteorite impacts. Some evidence exists for an impact around the time of the Permian extinction, but the author says this is inconclusive at this time."

Tornadoes, 2007.
A discussion of tornadoes from the viewpoint of an emergency management director.
1,329 words (approx. 5.3 pages), 3 sources, MLA, $ 44.95
»
Click here to show/hide summary
Abstract
The paper reveals that tornadoes are one of nature's most powerful forces. The writer explores the strengths of a tornado, the type of damage it does and the steps that can be taken to warn communities of its possible arrival. The paper discusses the Doppler radar system that can detect a tornado while it is still in the sky, the tornado siren system and trained human storm chasers and spotters. The paper explains that one of the problems with tornadoes is their unpredictability, but as emergency management teams nation wide continue to improve, the public will become increasingly safer.
Outline:
Introduction
Damages
Assessment
Warning the Public
Conclusion
From the Paper
"Out of all the natural disasters that can occur, tornadoes are often considered the most damaging and the most dangerous. While earthquakes are unpredictable, they have not developed a history in the United States of frequent occurrence or many deaths. Hurricanes, with the exception of Katrina usually provide enough advanced warning that the emergency management coordinators can provide notice to evacuate. Tornadoes, however, often strike with little or no warning and they can come in "swarms" during optimum weather conditions(Gugliotta, 2003)."

Abstract
The paper explores hydrothermal vents and their contribution to the many biological beings that make these extreme conditions their home. The paper defines a hydrothermal vent as nothing more than a geyser that occurs on the ocean floor. The paper supports the thesis that by examining the vents' reactions to continuously changing conditions in their environment, we can gain clues as to changes that are occurring in the earth's core.
Outline:
What Are Hydrothermal Vents?
What Can Life in the Vents Tell Us?
Life in an Alien World
From the Paper
"For the most part, the ocean floor is a sparsely inhabited area of the planet. However, hydrothermal vents are teeming with life. Hydrothermal vents are home to some extremely fascinating creatures to such as tube worms, giant clams, eyeless shrimp and spider crabs (ONR 2006). Cold seeps are other areas that are similar to hydrothermal vents, but the waters in them are closer to the temperature of the surrounding waters. Cold seeps support a similar array of life. Life around these geothermal fountains is dependent upon the chemicals in the surrounding water. The most common chemicals in the water include hydrogen sulfide, methane, iron, manganese, and silica (ONR 2006). This creates an extremely harsh environment to support life."

The Hydrologic Cycle, 2007.
An overview of the hydrologic cycle and a discussion of its various processes.
1,067 words (approx. 4.3 pages), 4 sources, MLA, $ 37.95
»
Click here to show/hide summary
Abstract
This paper explains that the hydrologic cycle is the term used to describe the continuous circulation of water in the Earth-atmosphere system. The paper then looks at how the most important processes that drive the hydrologic cycle are evaporation, transpiration, condensation, precipitation and runoff. The paper concludes that the extent to which people come to recognize the importance of water and the hydrologic cycle that drives it, will likely be the extent to which current and future conservation efforts will be successful.
Outline:
Introduction
Review and Discussion
Background and Overview.
Hydrologic Processes.
Conclusion
From the Paper
"While the hydrologic cycle keeps things continually changing, some things remain relatively the same. For example, Fisher (2001) points out that even with all of this movement of water around the planet, everything tends to end up right back where it started when all is said and done. "In the Water Cycle game," he says, "fair or not, the oceans have and keep almost all the wealth. The total of all the fresh (that is, not salty) water on land, including lakes, rivers, streams, ponds, puddles, bathtubs, kitchen sinks, and all the water under the ground, comes to only 2.4% of Earth's water. The atmosphere contains the rest, only .001% (that's 1/100,000th), in the form of water vapor and clouds" (Fisher, 2001, p. 14). In fact, this author emphasizes that it is this infinitesimal percentage of the water that is suspended in the Earth's atmosphere at any given point time is what keeps the whole system operating."
