Recommended: How does the acid rain effect the geosphere
When thought of acid rain, some people may think of green, burning acid falling from the sky, destroying everything in sight. This may be a bit ridiculous and hard to believe, but as absurd as it sound, it is not far from the truth. Acid deposition has long been a subject of debate because of the widespread environ-mental damage it is responsible for. As one of the major results of air pollution, acid rain can corrode metal and limestone structures, leach important minerals, decreased fertility of soils, and lower pH in lakes and ponds. For those who fear "the end of the world," acid rain may pose a threat as it creates a bad environment for both animal and human. And for those who care about our planet, maybe it is about time we stop destroying it and give something back to Mother Earth.
There are numerous causes of acid precipitation, several of these are insignificant and accumulate into severe cases. However, there are also some sources that are menacing by itself, sources such as industrial emissions. In some cases, acid rain is caused when industrial fumes mix with moisture in the atmosphere. Acids are then carried in clouds for long distances before they are deposited through rain, which indicates that forests and lakes far away from factories may be damaged by acid rain. Another significant cause of acid rain is automobile exhaust. Research has shown that although industrial emission makes up for most causes, sulfur dioxide from oil and coal combustion
and nitrogen oxides produced from automobile engines have greatly intensified the problem. Electric power plants are also to blame for this issue. Recent study has shown that power plants are accountable for the release of more than 20 million tons of sulfur Per. 3 dioxide each year. Meaning that 10 years from now, there would be around 30 million tons of acid rain components in our atmosphere. What's even worst than acid rain and its causes are the results. Acid deposition can cause a number of disasters, some of the serious effects includes structure eradication.
The marble frieze panels on the Parthenon of Athens for example, has been transformed by acid rain into gypsum. Loosing much of its details, the exterior of the Parthenon is also beginning to crack and flake off. The effects of acid rain can also be seen in lakes, rivers, and streams and plant growth.
The Industrial Revolution was not only a turning point in the progress of human history, but the start of a great change in the Earth’s environment. Technological advances in industry and mass migration into urban areas led to a rising demand for energy sources, a demand met by fossil fuels. Casper, J. (2010) describes coal as ‘symbolic of the beginning of the Industrial Revolution’, the increased combustion of these ‘dirty’ fossil fuels further polluted the air and enhanced the volume of Carbon Dioxide (CO2) in the atmosphere. Changes in land use attributed to population rise, reduced the amount of photosynthesising biomass on Earth, diminished an important ‘carbon sink’ and concluded to enhance the Greenhouse Effect.
Most of the acid rain pollution in our area comes from traffic, the creation of power, and manufacturing. Sometimes, fumes from manufacturing and power plants are created in the west and are blown eastward because
In conclusion, “Acid Rain: Scourge from the Skies” was effective in proving how severe acid rain is and can be. Robert Collins wrote informatively about a notable subject what anyone can comprehend and he used many commendable writing devices which all added to the effectiveness of the essay.
Rain is naturally acidic, due to the CO2 dissolved in it, however when sulphur dioxide and oxides of nitrogen react with the rain water they form sulphuric, and nitric acids which make the rain strongly acidic. SO2 + ½O2 + H2O → H2SO4 It may also take the form of snow or fog. The sulphur dioxides and oxides of nitrogen come mainly from industry. Acid rain is currently a subject of great controversy because of widespread environmental damage for which it has been blamed, including eroding structures, injuring crops and forests, and threatening or depleting life in freshwater lakes.
Rotting vegetation and erupting volcanoes release some chemicals that can cause acid rain, but most acid rain falls because of human activities. When humans burn fossil fuels, sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere. If large amounts of NO2 and SO2 are present in the atmosphere than the pH of rainwater will be significantly lowered. Nitric acid (HN03) can be linked to around 1/4 of the acid rain in the environment. Large amounts of NO gas is produced by high-temperature air combustion that takes place in car engines and power plants....
In reality though, not only did the British Museum damage these artifacts with their harsh cleaning implements, but also, upon being restored to Greece, the Parthenon Marbles would be kept in a well-equipped museum. The New Acropolis Museum has been recently built specifically to protect the Marbles. It was built to hold the Marbles in natural sunlight that characterizes the Athenian climate, arranged in the same way as they would have been on the Parthenon. This museum lies a mere three hundred meters from the Acropolis, allowing the Parthenon Marbles to be seen basking in the Greek sunlight as
The topic of this paper is acid deposition, also known as acid Rain. Acid rain is precipitation, as rain, snow or sleet containing relatively high concentration of acid forming chemicals. As the pollutants from coal, smoke, chemical manufacturing, and smelting, that have been released into the atmosphere and combine with water vapor, the harmful deposition is created (http://dictionary.reference.com/browse/acid+rain). Acid rain affects many things greatly.
Serial killers differ from other types of murderers. The number of serial killers in the U.S. is staggering. Differences are clear between serial killing and conventional murders. Serial killing can be classified as either motive based or organizational and social based. The Holmes Typology helps to understand the motivations behind serial killing. Serial killers may be even motivated by fame as part of their motivation for killing. John Wayne Gacy could be seen as evil due to his repeated violent acts. Jeffrey Dahmer was also evil by committing his acts of serial murders. Both Gacy and Dahmer had police records prior to their arrests for serial murders. Serial killers are poor candidates for rehabilitation. Their acts are evil.
It commenced in 2001 with the aim of halting the widespread decay that afflicted the ancient site of Herculaneum, and to develop a sustainable maintenance programme following immediate conservation. The project focuses on the urgent situations for structures and decorative features. It has been successful in reducing one of the major causes of decay by limiting water infiltration and pooling, as rain has a weathering and eroding effect that hastens the fading of paintings and frescoes. Rainwater damage also includes collapse of buildings, such as the crumbling wall of the Temple of Venus in Pompeii revealed in Source G. The ancient sewer network has been reinstated and since 2008 this drainage system has been used to collect and channel at the water towards the sea. Ensuring the protection of decorative features such as mosaics, frescoes and plasters is also difficult because they are often exposed to decay phenomena from the Mediterranean weather and climate of the Campania region. At the beginning of the Herculaneum Project, the state of decay of the decorations was very serious. It was common for individual features to experience multiple conservation problems, including plaster coming away from masonry, flaking of fragile paint layers, detachment and loss of mosaic tessarae. Part of the project involved safeguarding all the decorative features in a single building, working on a house by house basis, and performing conservation actions across the site where necessary. Since then there has been a general improvement to the overall stability of Herculaneum. Due to this success, many areas which were closed due to the fragility of their decorative features have now been reopened. Despite achieving its primary aim, the challenge now is in transforming this emergency works campaign into
Many people have a lot of trouble trying to understand exactly why serial killers do what they do, but in the killers minds they have certain motives that make sense to them. Holmes and DeBurger were two men who characterized serial murderers based on their motives. They “explain that the reward for killing is generally psychological even though some killers may benefit materially from their crimes” (Hickey, 2002). The first type of serial killers they described were the visionary type. These killers would be motivated by the commands,voices, or visions of some type of good or evil force. These killers usually suffer from some type of psychosis. The second type is the mission-oriented type who think it is their mission to rid the society of certain groups of people. The third type is the hedonistic type. These are the killers that get some type of thrill from killing their victims. The last type that Holmes and DeBurger categorized is the power/control-oriented type. These killers don’t get pleasure sexually, but rather get pleasure over simply having control and power over the helpless victim. The FBI has also tried to categorize killers by using profiling into “organized” and “disorganized” killers. The organized killers are often highly intelligent, charismatic, lives with a partner, and has controlled emotions during the crime. Unlike the organized killers, disorganized killers are very often below-average intelligence, live alone, high school dropouts, and have high anxiety during crimes. Although there is many different ways to categorize serial killers, they have been categorized both in a psychological perspective and also profiled by the
The building of the Parthenon was appointed by Pericles in 447 BC and was completed by 432 BC. The Parthenon was built on the Acropolis. The Acropolis is a sacred hill to the Greeks, and overlooks the city of Athens.The Parthenon has had quite a legacy in its time. In the 5th century, it was a temple. In the 6th through 15th century, it was a church. After the Turkish invasion and occupation of Athens, though, the Parthenon was turned into a mosque. Unfortunately, the Parthenon was destroyed to mere ruins by the Venetian invasion in the 17th century. The acid rain that came in later years also helped with destroying the Parthenon (Yeoh 65).
Although serial killers commit horrible crimes that normal people can never imagine doing, there are reasons as to why they do what they do. No matter how much research is done psychologists will never have one main reason as to why serial killers kill. This is because just as every snowflake is unique, every person’s motive to kill is unique.
The repairs that were made were a new wooden roof overlaid with clay tiles was put in to cover the entire Parthenon,this roof was more sloped than the original and it left the wings of the building
Recruitment and selection process are important and essential in the human resource management. Human resource management is a functional process that focuses on the management and recruitment of workers in an organization, also giving directions to workers in the organization. The purpose of recruitment and selection process are helping an organization to find the right person for the right position in a job, employees can know which person is suitable and needed in that specific position through the recruitment and selection process. Recruitment and selection process are about how an organization hire and choose workers during this process, employees are going to choose the most suitable workers and organize the most suitable work for them. (Gedaliahui & Shay, 1999)
Acid rain is when chemicals like nitrogen and sulphur-dioxide are released into the atmosphere and react with the water vapour, and acid pours in form of rain. This is very dangerous because it destroys infrastructures and some buildings, and also dissolves the human
