Volcanoes - 1,488 words
Which are the biggest (tallest and largest volume) and smallest volcanoes on Earth? The island of Hawaii is probably the largest volcano on earth. From its base (on the floor of the Pacific Ocean) to the summit of Mauna Kea (about 13 000ft) is some 30 000ft i.e. higher than Everest. The island comprises several coalescing volcanoes including Mauna Loa, Mauna Kea and Kilauea. Mauna Loa alone has an estimated volume of 40 000km**3. It is impossible to say which is the smallest volcano since there are thousands of small eruptions on the ocean floor and around already established volcanoes only a few yards across. Volcanoes are caused when molten rock from within the mantle breaks through the cr ...

... locked into the melted minerals. If volcanic rocks erupt on the earth's crust, such as the Andean volcanoes, then magma can interact with carbonate rocks such as chalk as it travels up through the mantle or lower crust, picking up carbon dioxide on the way. In subduction zones, where the ocean floor goes down into the mantle some carbonate rocks do get taken down and melted, recycling their carbon dioxide content, but this is a minor source compared with the mantle. Carbon is quite common deep in the earth, found either as the element itself (graphite or diamond under very high pressures), or as carbon dioxide. None of the common minerals in magmatic rock contains carbon, so when magma ...

EXPLORATION AND DISSECTION OF A MAMMALIAN HEART In this experiment, we obtained a fresh heart and dissected it to examine and observe the different parts of the heart, as well as studying how they function and work Problem: How can we study the heart through dissection? The most basic function of the circulatory system is to move the blood. The organ that provides the force to push the blood through the vessels is the heart. The mammalian heart is composed of four chambers to which large blood vessels are connected. The walls of these chambers are made of cardiac muscle tissue. It is the contraction of these muscular walls in a synchronized manner that moves the blood through this pump and i ...

A Look Into Volcanoes - 1,067 words
Volcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth's surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the best known, but the vast majority of the world's volcanoes lie beneath the sea, formed along the global oceanic ridge systems that crisscross the deep ocean floor. According to the Smithsonian Institution, 1511 above-sea volcanoes have been active during the past 10,000 years, 539 of them erupting one or more times duri ...

Explosive eruptions can eject liquid and semisolid lava as well as solid fragments of volcanic or nonvolcanic rock that have been carried along by the rising magma before eruption. Very violent explosive eruptions are called Plinian eruptions, after Roman naturalist Pliny the Elder. These eruptions can last for several hours to days and eject a large amount of pyroclastic material. Some volcanoes can produce much more energetic eruptions that eject materials farther from the vents because of their andesitic and dacitic composition. Andesitic and dacitic lava i ...

Hawaiian Volcanoes - 1,328 words
Viewing an erupting volcano is a memorable experience; one that has inspired fear, superstition, worship, curiosity, and fascination throughout the history of mankind. The active Hawaiian volcanoes have received special attention worldwide because of their frequent spectacular eruptions, which can be viewed and studied with a relative ease and safety. The island of Hawaii is composed of five volcanoes, three of which have been active within the past two hundred years. Kilaueas latest eruption still continues as of today. Mauna Loas latest activity was in 1984 and Hualalais in 1800-1801, but is likely to erupt again within the next one hundred years. East Maui, or Haleakala, one of the oldest ...

Acne - Skin's Miniture Volcanoes - 843 words
This purpose of this paper is to explain the cause of acne, give some examples, and how to get help prevent it. This paper will also dispel some of the myths of acne and how it is caused. Acne is a condition of the skin that ranges in appearance from raised bumps to pustules (large cysts and pimples). Acne is so common that more than 80 percent of the population will have some form of it at some time in some time of their lives. Although there are several theories about what causes acne, authorities generally believe that acne is a by-product of hormonal changes in the body during puberty- that period of life when a child develops the secondary sex characteristics (such as facial and body ha ...

Earthquakes, Volcanoes And Mountain Ranges - 579 words
Volcanoes, earthquakes and many of the great, in size, mountains (the Himalayas, Rockies, Urals, Alps, and the Appalachians) will all be marked on my map at some point in this project. Now just let me tell you some interesting facts about some of these topics. Since recorded history, 550 volcanoes have erupted on the earths surface, but even far more have erupted unobserved on the ocean floor. The enormous Himalayas and many other great mountains are known to be young Fold Mountains. Young, because these have been formed relatively recently in the earths history, compared to other mountain ranges like the Aravallis in India and the Appalachian in the USA. These are known as fold mountains be ...

Throughout The Little Prince, Antoine de Saint-Exupery uses his life experiences to help write this book. He uses his life to create a plot; these experiences will both be described in this paper, along with how they are related to each other. Exupery grew up in Saint-Maurice de Remens. He lived in a castle with a fairytale atmosphere. Joelle Eyheramanno stated that Antoines childhood turned around two poles, Saint-Maurice de Remens and his mother. His brother died when he was a teenager; during the years following his brothers death, his higher education was focused on astrology and literature. While in school, he was called for military service. The military introduced him to aviation. His ...

Auroras - 887 words
In certain polar regions of the earth, a rare and fascinating phenomenon occurs in the dark season of winter. This phenomenon is called the Northern Lights, or auroras. In areas where auroras can be seen, the sun shines brightly for six months and then disappears for the next six. The sun follows a straight path across the sky, rising in the north and setting in the south. This is because of the latitude of these regions. Unlike other regions of earth, the polar regions either completely face the sun or don't face it at all. During the first six months of the long, endless nights of dark winter, auroras are frequently seen, almost every night, in fact. During the rest of the year, the summer ...

The narrator, Richard Kiley, progressed through many points about our precious earth including her beginnings, her slow deterioration by man as well as other factors, and theories as to her what could be her end. The beginning images of earth, approximately four million years ago, can be described a barren yet fertile land with the prospect for life to flourish. Prehistoric volcanoes exploded with gases and lava, that created the crust of our land. Eventually the gases cooled and it began to rain, eventually forming the oceans that is the birthplace of life. Biologist Prof. Deemer believes that seasho ...

Policy Memo Global Warming - 1,815 words
Global Warming Is A Serious Issue That Should Have Immediate Attention As Vice President Al Gore has said about the threat of global warming, it is "the most serious problem our civilization faces" (2). It has become quite an issue internationally because of the threat of increasing greenhouse gasses. It is these gasses, when released into the air, accumulate and then trap the heat inside our atmosphere. Our climate is greatly affected by this. Therefore, affecting all of the organisms on earth, including humans. Usually these gasses should be able to move out into the upper atmosphere, where they are not as harmful. There are three important greenhouse gasses: Methane primarily comes from ...

Atlantis Fact Or Fiction - 1,005 words
... , the Atlanteans attempted to leave the continent in order to teach other civilizations what they had learned and about their culture (Starbuck). Arysio Nunes dos Santos has a different theory than the others. Santos places the continent of Atlantis in the Indies, India and Indonesia. So far this is the only place where there have been virtually no sightings of Atlantis. He believes that the remains of Atlantis lie at the bottom of the of the South China Sea. He also agrees with Plato on how Atlantis was destroyed and also when Atlantis was destroyed. With the location that Santos places this continent, it could explain why so many civilizations have made references to this mysterious is ...

Mt St Helens - 793 words
The two case studies I chose for my paper are the Mount St. Helen and Mount Pinatubo volcano eruptions. In this paper I will compare and contrasts the two volcanic eruptions on an individual, economic, and globally implications. The Mount St. Helens eruption took place on May 18, 1980. The eruption was designated as a five on the volcano index. The Mount Pinatubo eruption took place on June 15, 1991,and it was designated as a six on the volcano index. Mount Pinatubo eruption was about ten times larger than Mount St. Helens. Both volcano eruptions experienced a similar pattern. Both volcanoes had earthquakes before the actual eruption. Both eruptions generated tremendous amounts of ash and vo ...

Mountain Gors - 1,482 words
Mountain gorillas are the most endangered of the gorilla species. Approximately 600 or so remain. They are massive in size, with a short, thick trunk and broad chest and shoulders. Its eyes are very small in proportion to its other features. Older males develop longer heads, and are twice the size of females. The most severe threat to mountain gorillas is habitat loss. The fertile volcanic soil of the Virunga Mountains is as highly valued as farm land. Conservation programs have been set up in Rwanda, Uganda, and Congo to lessen trespassing. However, it still poses a major problem. By nature, gorillas are very shy and easy going, and seek no trouble. The only exception to this is if the fami ...
