  • 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 ...

  • To What Extent Does Acid Precipitation Affect Annelids - 648 words
    To What Extent Does Acid Precipitation Affect Annelids? In order to truly understand acid rain and it's eventual effect on earthworms, it would be best to look at the causes of acid rain. How and why does altered acidity in precipitation have a devastating effect? Acid rain is charecterized as "Precipitation that has a pH lower than about 5.0" (Allaby, Michael (1994) Ecology, Oxford Press,). Acid rain is created by many things, of which pollution from cars contributes the most. Ever since the Industrial revolution, the acidity of rain has been haywire. Sulfur and nitrogen are found widely throughout the world in the air, "even in unindustrialized tropics" (Graedel, Thomas, et. al, (1989, V26 ...

    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 ...

Osmoregulation is the process of maintaining the delicate balance of salts and minerals in their tissues. For freshwater fish, maintaining osmoregulation is key in their survival. Acid molecules, which are a result of acid rain in the water, cause mucus to form in the fishs gills. This in return prevents the fish from absorbing oxygen. If the fish are unable to absorb oxygen, the consequence could be the eventual suffocation of fish and the low pH could throw off the balance of salts in the fish tissu ...

    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 ...

    ... . 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 Introduction: What Causes Acid Rain? One of the main causes of acid rain is sulfur dioxide. Natural sources, which emit this gas, are Volcanoes, sea spray, rotting vegetation and plankton. However, the burning of fossil fuels, such as Coal and oil, are largely to be blamed for approximately half of the emissions of this gas in the world. When sulfur dioxide reaches the atmosphere, it oxidizes to first form a sulfate ion. It then Becomes sulfuric acid as it joins with hydrogen atoms in the air and falls back down to earth. Oxidation occurs the most in clouds and especially in heavily polluted air where other compounds such as ammonia and ozone help to catalyze the reaction, changing ...

  • 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 ...

  • Air Pollution - 1,567 words
    Air Pollution Acid rain is a problem that has plagued earth for years. It is poisoning our waters, animals, plants, soil, and more. It is a problem that can not be ignored or it might have catastrophic results on our environment. Acid rain is caused by air pollution, which is due to man-made actions. Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Power plants and factories burn coal and oil, which is used to produce the electricity we need to heat and light our homes and to run our electric appliances. We also burn natural gas, coal, and oil to heat our homes, and our cars, trucks, boats, and airplanes use gasoline to run, whic ...

    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 ...

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 ...

  • Air Quality - 1,726 words
    Air Quality Air Quality & Dispersion Today, the air quality aspect of ARL research is by far the dominant theme, but distinctions among the themes remain somewhat vague. For example, the models developed for emergency response purposes are among those used for air quality prediction. The Air Quality and Dispersion theme is one of the strongest ties that binds ARL's components together. ARL is not heavily involved in the pure science of the business. Instead, ARL focusses on the need to assemble integrated understanding and models from all available sources, to develop the capability to predict changes in air quality that will follow changes in emissions, or that will occur as a result of met ...

I'm not sure what Albania should do for the next ten days, let alone ten years. But, I will try to discuss economics and resources. Second, past and current military and diplomatic policy. Finally, I want to tie all of this to the idea of adopting the policies and philosophies of the Western democracies. Only through the aid, encouragement and protection of the West, can Albania hope to make progress for itself and it's citizens. Economics Albania is the poorest country in Europe.

The people of this area did not totally arrive until the English had colonized the coast of the eastern seaboard forcing the now Appalachian people westward to the interior mountains. The main influx of people came in on the second wave of migrants. This people were of Scotch Irish, German, Welsh, French and Swiss decent. These people from the start were rugged mountain people that were very self sufficient and mainly lived from farming as there means of survival. In the beginnin ...

  • Aztec Nation - 2,986 words
    Aztec Nation The Aztec Nation A distant sound is heard. It sounds like a deep drum being hit with a heavy instrument. You hear it again and strain your eyes in the direction of the sound. All around you is dense jungle. Snakes slither between your legs. You hear the sound once again. In front of you is a dense stand of ferns. You part them and look down into a wide open valley. The valley gets so wide and it is so green that it takes your breath away. But that is not what you are looking at. You are staring at a huge city with glittering buildings shining in the spring sunlight. Smoke rises up from some of the many houses. You can see and hear children playing in the wide open fields in fron ...
