  • Carbon Dioxide - 319 words
    Carbon Dioxide Carbon dioxide has been rising in the atmosphere throughout time. Recently though, the levels of carbon dioxide have been increasing at a more alarming rate. The cause of this is a direct result of mans burning of fossil fuels. We know that every action we make, as humans, will have some effect on the environment around us and those effects can be either good or bad. The rising levels of carbon dioxide in the atmosphere may potentially inflict some negative effects on our environment. The termed used to describe the rise in CO2 in the atmosphere is the greenhouse effect. Major greenhouse gasses include carbon dioxide, water vapor, and methane. Greenhouse gasses collect in the ...

  • Combustion Carbon Dioxide - 1,146 words
    COMBUSTIOn & carbon Dioxide Research By Rabon Hutcherson II. Combustion and carbon dioxide, what are they? When people think of combustion they probably think of simple just bursting into flames; and for carbon dioxide you probably think of what we breath out and what plants take from the air and turn to oxygen. Even though these thoughts are true there is much more to combustion and carbon dioxide. Things you might not think of about combustion are, mathematical equations, models, solutions and chemical reactions, and for carbon dioxide dry ice, combustion and it being a solid. All of these factors you may not have known are now here for you to see. One of the things that has lead the way f ...

  • Combustion Carbon Dioxide - 1,127 words
    ... carbon dioxide plus carbonic acid. The carbonic acid can neutralize hydroxide ions which if added, would increase the pH of the blood and cause alkalosis. The bicarbonate ion can neutralize hydrogen ions that, if added, would cause a decrease in the pH of the blood and lead to acidosis. Both changes in pH are life threatening. The carbon dioxide in the earth's atmosphere helps regulate the planet's temperature. When sunlight reaches the earth, some of it is converted into heat. The carbon dioxide absorbs some of the heat and so helps keep it near the earth's surface. If all the heat from the sunlight escaped into outer space, the earth would become very cold. The amount of carbon dioxid ...

  • Is Carbon Dating Accurate - 420 words
    Is carbon dating accurate? Carbon dating, used since 1948, is currently the main method of testing artifacts for age. My objective through this essay is to disprove the accuracy of the Carbon 14 dating method. William Libby invented carbon dating in 1948. It works on the principle that the carbon 14-C, is radioactive. It decays at a "known" rate called a half-life. This is balanced by the fact that 14-C is constantly produced in atmospheric reactions. Because of this, 14-C and its breakdown product 12-C, typically stay in balance. Carbon is passed between the ocean, atmosphere, and living things in the "Carbon Cycle". When an animal dies it is taken out of the carbon cycle. After this, the p ...

  • 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 ...

  • 2001: A Space Odyssey - 1,255 words
    2001: A Space Odyssey The concept of space travel has been an interest to many since the beginning of time. Today, scientists are moving at a comfortable pace to expand our vast knowledge of the universe. Many authors dreamed of the possibilities while scientists tried to bring them to reality. The book "2001: A Space Odyssey," written by Arthur C. Clarke in the 1960's, proposed ideas about advanced space travel that took place in a time period only two years from now; however, at the current rate of the space program, mankind is nowhere near the technology showed by the book. Clarke uses concepts of space travel that can still only be dreamed of today. Clarke, an author of the sixties, had ...

  • A Galaxy - 540 words
    A Galaxy A Galaxy: Characteristics, Contents and Types Galaxies are huge and contain billions of stars. They contain all of the stars of the Herzspring-Russell diagram, open cluster, emission, nubula, reflection nubula, nova remnants and supernova remnants. We have three different and distinct types of galaxies, which are spiral galaxies, eluptical galaxies, and last but not least irregular galaxies. The Milky Way galaxy, which is a representative of a spiral galaxy, is basically lens-shaped. Its circumference is about 120,000 light years across. On a dark summer night, we are able to see a few of the Milky Way's arm. The Milky Way, as all spiral galaxies, rotates on its axis. However, it do ...

    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 - 1,218 words
    Acid Rain Acid rain is a serious problem with disastrous effects. Each day this serious problem increases. Many people believe that this issue is too small to deal with right now, and others believe it should be met head on. In the following paragraphs I will be discussing the impact of acid rain effects on wildlife and how our atmosphere is being destroyed. Causes Acid rain is a cancer, eating into the face of Eastern Canada and the North Eastern United States. In Canada, the main sulphuric acid sources are non-ferrous smelters and power generation. On both sides of the border, automobiles are the main sources for nitric acid (about 40% of the total). Power generating plants, industrial com ...

  • 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 - 1,013 words
    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 - 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 ...

  • Acid Rain - 312 words
    Acid Rain Acid Rain Acid rain forms high in the clouds in a gaseous form. Theses gasses stay in the atmosphere until they come in contact with rain that dissolves the gasses. A mild solution of sulfuric and nitric acid is formed. These drops fall to the earth and get into our water table beneath the surface. From there they are collected into streams, rivers, and lakes that eventually will lead to the ocean. Rain isn't the only form acidity falls to the earth. About half of all the acidity falls back through dry deposition as gasses and dry particles. The wind blows the acid particles onto cars, homes, trees, and buildings. The acid discharge is then washed from the surfaces by rain. The run ...

  • 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 ...

  • Active Transport - 1,302 words
    Active Transport Since the cell membrane is somewhat permeable to sodium ions, simple diffusion would result in a net movement of sodium ions into the cell, until the concentrations on the two sides of the membrane became equal. Sodium actually does diffuse into the cell rather freely, but as fast as it does so, the cell actively pumps it out again, against the concentration difference. The mechanism by which the cell pumps the sodium ions out is called active transport. Active transport requires the expenditure of energy for the work done by the cell in moving molecules against a concentration gradient. Active transport enables a cell to maintain a lower concentration of sodium inside the c ...

  • 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 ...
