  • Cold Water Discovered In The Subtropical Atlantic Was Brought There By A Current Which Had Originated In The Polar Region Tem - 638 words
    Cold water discovered in the subtropical Atlantic was brought there by a current which had originated in the polar region; temperature measurements in the real ocean and computer models show there is a southward outflow of cold deep water from the Arctic throughout the Atlantic. This cold water is replaced by warm surface waters, which gradually give off their heat to the atmosphere as they flow northward towards Europe. This acts as a massive heating system for all the land downwind. The heat released by this system is enormous: it measures around 1015 W, equivalent to the output of a million large power stations. If we compare places in Europe with locations at similar latitudes on the Nor ...

  • El Nino Has Been A Reoccurring Phenomenon For Centuries Man Has Only Started To Realize How Much Of The Worlds Weather Is Eff - 1,334 words
    El Nino has been a reoccurring phenomenon for centuries. Man has only started to realize how much of the worlds weather is effected by it. The term El Nino refers to an irregular warming of the seas surface. During the last 40 years there have been 10 significant El Nino occurrences. Most affecting the coast of South America. Water temperatures increase along the coast as far as the Galapagos islands. Weak events will raise the water temperature 2 to 4 degrees Celsius and will have minor impact on fishing. However strong events such as the 1982-83 event will disrupt climate conditions around the world as well as local conditions. It has been linked to floods and droughts all over the world. ...

  • Freshwater Regions - 1,507 words
    Freshwater Regions Freshwater is defined as having a low salt concentrationusually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e, ocean). There are different types of freshwater regions: ponds and lakes, streams and rivers, and wetlands. The following sections describe the characteristics of these three freshwater zones. Ponds and Lakes These regions range in size from just a few square meters to thousands of square kilometers. Scattered throughout the earth, several are remnants from the Pleistocene glaciation. Many ponds are seasonal, lasting just a couple of months (such ...

  • Introduction - 1,018 words
    INTRODUCTION Ecology is the study of living things interacting with its environment, other species, and its own kind. Its a study of all external condition and factors, both biotic ( living ) and a-biotic ( nonliving ), that affect an organism. To carry out this study, scientists observe different ecosystems: forests, deserts, grasslands, oceans, or any kind of interaction between organisms and their surroundings, or with each other, which are called ecosystem effects. There are four components within an ecosystem. The a-biotic component, which determines the types of organisms found there, the producers, the consumers, and the decomposers. These components cause continual change within the ...

  • Lithosphere - 1,200 words
    Lithosphere Notes on the lithosphere- (rock sphere) Upper most part is crust of earth. Compiled of rocks of outer crust. Outermost shell. Upper part- rocks we see at and near the earths surface. Crust is 5 to 10 km thick under most oceans and 24 to 60 km thick under the continents. The lithosphere under the crust is solid, dense material. (more dense than surface materials). Lithosphere 100-200 km. Notes on the aesthenosphere- zone beneath the lithosphere. Thick like tar. Weak because of high teperatures at that depth. Density- 2.7-3.4 to about 12. Notes on the hydrosphere- (Water-bearing) Too small due to the irregularity of upward projection. Density-1.1 Notes on the Atmosphere- only 10 km ...

  • Oceanography From Space - 1,181 words
    Oceanography From Space At first thought, studying the oceans from space seems to be a bizarre idea. Space observation helps oceanographers do research with manned and unmanned space systems. The space systems can be satellites and/or space shuttles that observe various features of the ocean such as sea-surface winds, sea-surface temperatures, waves, ocean currents, frontal regions, and sea color. Technological advances have greatly improved the ability of oceanographers to gather and use information that is received. Oceanography as viewed from space has and will become more and more valuable as we begin to understand more of the world's oceans. Projects Space oceanography uses a number of ...

  • The Artic - 930 words
    The Artic Introduction. The Artic is a region at the upper most tip of the Northern Hemisphere. The Artic includes the area around Greenland, USSR, Canada and Alaska. Much of the Artic circle is permanently frozen ice. The Artic is a pristine environment, clean and void of human interference. However as humans move into these areas and begin to extract what ever they can be balance can be tipped, resulting in pollution and destruction of the environment. Climate. The Artic winters much longer than the Summer. In the winter the sun never rises and in the summer it never sets. The average temperature for the Artic is zero degrees of less. Industry and the Artic. There was once a time when the ...

  • The Greenhouse Effect - 1,125 words
    ... ffect worldwide temperatures dramatically. In 100 years time the average temperature for most parts of the world will increase from between 2 degrees C to 6 degrees C if greenhouse pollution continues at its present rate. (Baines, p. 190) This temperature increase would drastically affect the growth of many different crops and cause the polar ice caps to melt, thus increasing sea levels. If this rise in sea level was to occur many areas would be much more prone to flooding, and generally much deeper floods would be experienced than nowadays. This flooding would happen particularly around coastal regions worldwide, and also along many rivers that flow to or from coastal inlets. The greenh ...

  • 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 ...

  • The Pequod's Leaders: Their Differing Characteristics - 584 words
    The Pequod's Leaders: Their Differing Characteristics L.R.G. Captain Ahab, First Mate Starbuck, Second Mate Stubb, and Third Mate Flask. From the time they are first introduced, the Pequod's leaders are noticeably very different from each other. Almost everything is different about these men save the fact that they are all four on a whaling ship. Why did Melville take such care to develop these four men as he did? Would the story have been as profound without these distinct character foils? Probably not. I think what Melville was trying to accomplish by having such differing personalities aboard the Pequod was to keep the reader interested on the personal level of the story as well as to put ...
