fresh water



One of the earth's most precious resources is in great peril. Water, the substance
required by all living beings as a means of survival, is succumbing more and more to the
ravages of pollutants, most -- if not all -- of which are the cause of humanity's
environmental carelessness and neglect. Indeed, water sources of decades past were only
beginning to show the signs of contamination, still remaining well within the parameters
of what is considered to be safe; however, the water sources of late are clearly
demonstrating the consequences of overwhelming pollution by killing off a significant
amount of the plant and animal life that depends upon it for existence. What is being done
to correct this drastic situation is too little too late according to critics, who contend
that the world's water source has been left to fight for its health for far too long to be
expected to regain its soundness

  • Study on Rana Pipiens
    Study on Rana Pipiens Leopard Frog - Rana Pipiens Distribution: Found throughout Ontario but more abundant in southern and central Americas. Range: Adults maintain small home ranges (up to 500 m2) in fields or open forest during the summer. Where terrestrial habitats are quite dry, home ranges include some shoreline. A minimum of 4 ha of terrestrial habitat is recommended for the vicinity of breeding sites, however, individual adults may move several kilometres away. Most recently metamorphosed

  • Soil erosion
    Soil erosion SOIL EROSION Soil erosion is a gradual process that occurs when the actions of water, wind, and other factors eat away and wear down the land, causing the soil to deteriorate or disappear completely. Soil deterioration and low quality of water due to erosion and run off has often become a severe problem around the world. Many times the problems become so severe that the land can no longer be cultivated and is abandoned. The key to minimizing soil erosion and saving the farm lands is

    Invasion of Salvina Molesta kariba weed Introduction The plant Salvinia molesta , generally known as Giant Salvinia or Kariba weed, is a free floating pterophyta indigenous to south-east brazil (Julien et. al 1987). Today plants and animals are shipped, sometimes accidentally, all over the globe to zoos, botanical gardens, and for commercial and agricultural purposes. A small minority of alien plants, or introduced, species become ecological as well as economic disasters. Although they may hav

    GIS Geographic Information Systems Geographic information systems (GIS) technology can be used for scientific investigations, resource management, and development planning. For example, a GIS might allow emergency planners to easily calculate emergency response times and effected areas of the ocean during an oil spill based on the spills location. You may ask, what is GIS? In the strictest sense, a GIS is a computer system capable of assembling, storing, manipulating, and displaying geographical

Wetlands are found in flat vegetated areas, in depressions on the landscape, and between water and dry land along the edges of streams, rivers, lakes, and coastlines. Wetland areas can be found in nearly every county and climatic zone in the United States. Inland wetlands receive water from precipitation, ground water and/or surface water. Coastal and estuarine wetlands receive wat

Over the next few millennia, the building of dams for water retention spread throughout the Mediterranean, the Middle East, Southern Asia, China, and Central America. Later, as technologies increased and industrialization took hold in Europe, dam mechanisms advanced to incor

  • Radio Carbon Dating
    Radio Carbon Dating Radiocarbon Dating When we think of history, we think of important people, places, cultures, events, and much more. The backbone of history rests on its chronology. It gives us the "when" of basic analysis. It gives us a frame of reference, the order of things. Before having an "absolute" way of determining dates, history was based in guesses and assumptions. Many attempts were made to organize the dates of the past. Some of these attempts were made by geologist. Geologist u

  • Global Warming
    Global Warming Two issues that worry many geologists are global warming and the greenhouse effect. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming? When humans release gases into the air, the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer, and the result is global warming. On the other hand, if there was

Rising in the Alps, it passes through Lake Geneva (French: Lac Leman) to enter France, which has 324 miles of its total length of 505 miles. At Lyon it receives its major tributary, the Saone. In eastern France the direction of the main rivers is predominantly north-south through the Alpine furrow. The regime of the Rhone is complex. Near Lyon the Rhone and its important Isere and Drome trib
