  • The Greenhouse Effect The Greenhouse Effect Occurs When Gases Such As Methane, Carbon Dioxide, Nitrogen Oxide And Cfcs Trap H - 1,072 words
    The Greenhouse Effect The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methane which comes mainly from animal manure. Other gases like nitrogen oxide and man made gases called chloroflurocarbons get caught in the atmosphere as well. The decay of animals and respiration are two mai ...

  • A Hill Of Fury: - 846 words
    A Hill of Fury: Soufriere Hills Volcano, Montserrat Island After 400 years of quiet slumber, the Soufriere Hills volcano on the tiny island of Montserrat in the Carribean Sea (Figure 1), came to life in the summer of 1997. The eruptions threatened the original 11,000 residents of the island and even today continue to be a nuisance to the remaining 4,000 people who refuse to leave the island, despite warnings of impending danger. At least 20 people have already been killed, and several villages destroyed. The Montserrat Volcano Observatory analyzes the active volcano and provides information to scientists and residents of the island (Montserrat Volcano Observatory 12). The worst of the erupti ...

    A vogadro was born on June 9, 1776 in Turin, Italy. He began his career in 1796 by obtaining a doctorate in law and practicing as a lawyer for three years after. In 1800, he began to take private lessons in mathematics and physics and decided to make the natural sciences his profession. He was appointed as a demonstrator at the Academy of Turin in1806 and the Professor of Natural Philosophy at the College of Vercelli in 1809, and in 1820, he was appointed the professor of mathematical physics. He was a physics professor but he also experimented in chemistry using mathematics to base most of his findings. Avogadro is well known for his hypothesis known as Avogadro's Law. His law states that a ...

    Abortion "You wake up in the morning and find yourself back to back in bed with an unconscious violinist. A famous unconscious violinist. He has been found to have a fatal kidney ailment, and the Society of Music Lovers have canvassed all the available medical records and found that you alone have the right blood type to help. They have therefore kidnapped you, and last night the violinist's circulatory system was plugged into yours, so that your kidneys can be used to extract poisons from his blood as well as your own. The director of the hospital now tells you, 'Look, we're sorry the Society of Music Lovers did this to you-we would never have permitted it if we had known. But still, they d ...

  • 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 ...

    Acid Rain Pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous, to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or cloud vapors. The acidity of substances dissolved in water are measured by their pH levels. Normal precipitation pH levels fall between 5.0-5.6.2 When levels fall below these numbers, then the precipitati ...

  • Acid Rain - 1,774 words
    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 ...

    ... . These particles collect on the leaves of the tree, and studies have shown that when these particles contain acid they can cause damage to the leaves. The leaves are the part of the tree that help make food, hence any damage to the leaves will result in harm to the health of the entire tree. Coniferous trees are vulnerable to the harmful effects of acid rain as well. The tree's needles are designed to nourish the tree after they fall to the ground. Each needle houses whole colonies of microscopic bacteria and algae that help the tree change nitrogen into food at the roots. Acid rain will often burn away this material, thereby reducing adequate food supply, and weakening the tree's healt ...

  • 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 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 ...

  • Against Ufos - 809 words
    Against Ufos UFOs: Neither Here nor There Throughout the past, the existence of unidentified flying objects and aliens has been disputed over and over. Many different platforms and viewpoints have been taken in order to support the respective sides of the issue. The main argument against intelligent life existing somewhere other than Earth is that of where they derive. The truth of the matter is there is no place in the universe that UFOs and aliens could exist. Skeptics are faced with the fact that modern science has stated that no other orbital body in our solar system or immediate surrounding area is able to sustain life (Blum, 1990). Our solar system is a collection of planets, comets, a ...

  • Air Pollution - 1,546 words
    Air Pollution Air Pollution is addition of harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life. One of many forms of pollution, air pollution occurs inside homes, schools, and offices; in cities; across continents; and even globally. Air pollution makes people sick, it causes breathing problems and promotes cancer, and it harms plants, animals, and the ecosystems in which they live. Some air pollutants return to earth in the form of acid rain and snow, which corrode statues and buildings, damage crops and forests, and make lakes and streams unsuitable for fish and other plant and animal life. Pollution is changing the earth's atmosph ...

    ... ures have in fact been rising, and the years from 1987 to 1997 were the warmest ten years on record. Most scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is on its way. Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate change are unknown, some predict that exaggerated weather condi ...

  • Air Pollution - 375 words
    Air pollution Heres a little introduction to this project. There are always two ways to look at something. There is the good way, which in this case would mean looking at all the positive effects that human intervention has created, These are very few if there are any at all! Also, there is the other way. This would be the bad way consisting of basic criticism of all the negative effects that human intervention has caused. These are quite a few and therefore we shall talk about them. Fortunately for the Amazonian forest, I am not going to write about every single thing connected to the negative effects on the environment, but I will talk about several cases, all connected some how to polluti ...

Ozone depletion is looked upon as a problem that up till now, we can not fix. Air pollution has caused this hole in the ozone layer. The ozone layer absorbs 99% of the sun's harmful energy. It prevents ultraviolet radiation from reaching the Earth's surface and the troposphere. It protects humans from sunburn, skin and eye cancer, and cataracts. It also prevents much of the oxygen in the troposphere from being converted to ozone (gas). In the mid-seventies chemists F. Sherwood Rowland and Mario J. Malian discovered CFC's were creating a global chemical time bomb by ...

You step further into the street be it busy or not, and you begin to turn in 360 circles. For what your eyes behold is far from anything you have ever seen. A circle of green and blue swirl through the night sky, I could best describe this as two ballroom dancers doing a Waltz through the night sky. They flow, they glide so gracefully that they capture you and keep you entranced for a very long time. This my first experience viewing the amazing Aurora Borealis, it did not matter that people were watching, or that the roads were iced over and that I could not stand on ...
