  • Effects Of Acid Rain On North Americas Aquatic Ecosystems - 1,898 words
    Effects Of Acid Rain On North America's Aquatic Ecosystems 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 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 For years ever since most of the world has been industrialized, the effects of pollution have plagued nations alike. Acid rain is one of the largest contributors to this industrialized form of pollution. Throughout this report an explanation of the devastating effects to the environment caused by acid rain will be given along with what is being done to stop it. Acid rain is made when pollutants arise from the use of coal in the production of electricity, from base- metal smelting and from fuel combustion in vehicles. Once the sulfur and nitrogen oxides from these man made causes are released into the air they are caught by wind currents and are blown hundreds of miles away. The gas ...

    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 ...

  • Acid Rain - 1,731 words
    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 Legislation - 824 words
    Acid Rain Legislation Acid Rain Legislation Acid rain is a destructive force as a result of nature and man colliding. It is formed through harmful industrial emissions combining with contents of the earth's atmosphere; a dangerous combination. This prompted governments throughout North America to take action. Many laws and regulations have been implemented, yet the question still remains, Should tougher legislation be implemented to force industries to reduce acid rain emissions? To decide whether tougher legislation should be implemented, one must first understand the details of what exactly acid rain is. Acid rain is a result of mankind's carelessness. It travels a long one of the most eff ...

  • 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 ...

Furthermore, every time the trout moved, it always returned to the same position it left from. Conveniently, the trout may have used the three stones at the base of it's schooling position as a marker Also, the school showed something that resembled a hierarchy of order. It appeared that the larger fished floated toward the bottom, while the smaller fished floated at the top. During the observation period, the fish dispersed in a rapid manner on three occasions. On the first random dispersement, no significant signal was apparent. However during the second rapid dispersion! ...

  • Animal Species - 650 words
    Animal Species Living creatures on Earth need three basic things in order to survive: the ability to eat, breath, and reproduce. All animals are able to do so. Animals are divided into species, among these species are: Mammals, Reptiles, Arthropods, and Aves. Mammals, also known as Mammalia, come from Latin meaning mamma breast. They are called this due to the fact that Mammals are the only animals which have mammary glands, which enable them to nourish their young solely on milk secreted from these glands. Mammals are warm blooded, and all, except for marine mammals, are mostly or completely covered with hair. Mammals give birth to live young, however, there are a few rare exceptions to thi ...

  • Aquaculture - 1,393 words
    Aquaculture Aquaculture is the farming of aquatic organisms in fresh, or salt water. A wide variety of aquatic organisms are produced through aquaculture, including fish, crustaceans, mollusks, algae, and aquatic plants. Unlike capture fisheries, aquaculture requires deliberate human intervention in the organisms' productivity and results in yields that exceed those from the natural environment alone. Stocking water with (juvenile organisms), fertilizing the water, feeding the organisms, and maintaining water quality are common examples of such intervention. Most aquacultural crops are destined for human consumption. However, aquaculture also produces bait fishes, ornamental or aquarium fish ...

  • Bacteria Reproduction - 916 words
    Bacteria Reproduction Bacteria are microscopic singular celled organisms grouped in the prokaryote kingdom. They have a seemingly simple internal structure but that is not so the internal structure of a bacterium is quite complicated . Bacterial growth is generally studied in cell cultures by "visible count" estimation which shows an apparent growth curve. (Stephenson 50) The growth curve shows the stages of bacterial growth within a cell culture. (Thimann 623). Bacteria can survive in a number of different extreme environments from extreme heat to little water. Bacterium have a internal structure that is more complicated than it seems at first. The first part of the bacterium is the plasma ...

The first and most top layer is the emergent, which are widely spaced trees 100-120 ft tall with canopies above the general canopy of the forest. The second, middle layer is a closed canopy of 80-foot trees. Here light is available to this layer, but blocks out the light of lower lays. The third layer is a closed canopy of 60-foot trees. This is where little air movement occurs and there is high humidity. Another lower layer is the shrub/sapling layer. In this place of the forest less than 3% of light reaches ...

Most people believe that the migration north and the migration south are the same but actually they are different (Breen). The migration north to the breeding grounds is a slower and more relaxed one than that of the one moving south (Wormer). The migration north sometimes begins in late January for Canada Geese that are wintering far south, but the majority of movement occurs in March (Resource Reader). The femal ...

  • Causes Of Endangered Species - 1,209 words
    Causes Of Endangered Species CAUSES OF ENDANGERED SPECIES The term endangered is used by international and national organizations to define plants and animals currently in danger of becoming extinct. Although the term endangered is universally used, the definition of an endangered species is greatly varied. In most cases, the factors causing an organism to become endangered are human- related. When discussing the causes of endangered species, it is important to understand that individual species are not the only factors involved in this dilemma. Endangerment is a broad issue, one that involves the habitats and environments where species live and interact with one another. Although some measu ...

    Costa Rica Greg Coffta Bio190/Costa Rican Adventures 11/30/1999 Part I Banana: Bananas were most likely picked up by the European traders in Southeast Asia when in search for spices. Soon, as the discovery of the Tropics arrived, traders took bananas to Central America. Breadfruit: this fruit commonly grows among the southern Pacific islands, and it probably found its way to Costa Rica when the natives started to explore on boat. Chocolate: as far as I could find, chocolate is native to Central America. It comes from the fruit of the Cacao Tree, and was traditionally used by the Aztecs. Coconuts: Coconuts also come from Tropical Pacific islands, and the actual coconut itself probably floated ...
