Mountains
Mountains I. INTRODUCTION A mountain is an elevated land mass usually higher than its surroundings. Some are isolated, but they usually appear in ranges(MsBs95W32). A group of ranges closely related in form, origin, and alignment is a mountain system; an elongated group of systems is a chain; and a complex of ranges, systems, and chains continental in extent is a cordillera, zone, or belt.(MsBs95W32). Some mountains are remains of plateaus, mesas, and buttes, through erosion(Summerfield). Oth...

New Zealand First Appeared About 140 Million Years Ago, During The Mes
New Zealand first appeared about 140 million years ago, during the Mesozoic Era. This landmass gradually eroded until about 80 million years ago, when sea floor spreading started and the Tasmanian sea formed. However, it wasn't until 10,000 years ago when the land formed the shape, as we now know it. The oldest rocks in New Zealand are approximately six-hundred and eighty million years old. These rocks were found on the west coast of the South Island. Although, at one point in its history, New ...

The Caribbean Sea Is Geologically Separate From The North And South Am
The Caribbean Sea is geologically separate from the North and South American continents. Together with Central America, it forms a tectonic plate which is moving W at about 4 cm a year. At the same time, the North American and South American plates, which lie under the continents and the eastern half of the Atlantic Ocean, are moving W. Most of the Caribbean islands are close to the boundaries of the Caribbean plate. Plate boundaries are geologically active; this is why most parts of the Caribb...

Volcanoes
Volcanoes By Tricia Severson 2nd hour Science 4/30/98 A volcano is a vent, or opening, in the surface of the Earth through which magma and associated gases and ash erupt. The word also refers to the form or structure, usually conical, produced by accumulations of erupted material. Volcanoes occur mainly near plate tectonic boundaries and are especially common around the Pacific basin, called the Pacific Ring of Fire (see Plate Tectonics). ???Humanity has long been awed by this powerful force of...

Shiven Patel
Shiven Patel The geography of China and Japan is quite different. They are both located in Eastern Asia, but China is apart of the mainland, while Japan is a group of islands off in the North Pacific. China, the world's fourth largest country, is considerably larger than Japan. China has a total area of 9,596,960 square kilometers while Japan is only 377,8356 square kilometers. Of course Japan has double the coastline of China for it is an island chain. China has an eastern coastline along the ...

The Greenhouse Effect
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...

It Has Been Said That A Country That Goes Through Hard Times, Will Oft
It has been said that a country that goes through hard times, will often rebound and become stronger as time passes by. Guatemala is one of those countries. It may not be situated in an area of peace and wealth. It may not have the best medicine. It may not have enough of an army to defend its patriots. All in all, Guatemala has survived through the many hardships and warring and has come out as the stronger of the nations. Guatemala may not be the best of the best, but it has survived through ...

Literary Criticisms Of Emily Dickinsons Poetry
Literary Criticisms of Emily Dickinson's Poetry -1- Throughout Emily Dickinson's poetry there are three main themes that she addresses: death, love, and nature; as well as the impact of the word. When discussing these themes she followed her lifestyle and broke away from traditional forms of writing and wrote with an intense energy and complexity never seen before and rarely seen today. She was a rarity not only because of her poetry but because she was one of the first female pioneers into t...

This Theory Of The Universe Is Based On The Ideas Of A Caveman, Named
This theory of the universe is based on the ideas of a caveman, named that lived many thousands of years before the birth of Christ. His observations were made only through the use of his body, for there were no tools to aid him in his findings. His findings were based on his observations and the accepted views of the world during his lifetime. This is what he had to say: The earth was the center of the universe. This is an absolute, indisputable fact because it is obvious that the moon, sun, a...

Lab Report The Structure Of The Earth Is Made Up Of Many Layers, But T
Lab Report The structure of the earth is made up of many layers, but the crust and the upper mantle make up the lithosphere. The lithosphere is divided into individual sections called plates. The rest of the mantle makes up the asthenosphere. Convection in asthenosphere causes the plates to shift and move about. We can tell where the plates are or have been because volcanoes and earthquakes have their own boundaries when the are active. Tectonic plates have three relationships with each other. T...

Mountain Gorillas
Mountain Gorillas Half man and half beast. This is what is usually said about the gorilla. They say that the gorilla is related to us. You can find mountain gorillas in the Virunga Volcanoes, which are located on the boundaries of Zaire, Rwanda, and Uganda. The Virungas are 600 miles of tropical rainforest. You'll find then roaming around 7,800 and 11,000 feet, but at low elevations. The gorillas live in units. Most of the units consist of about 6-12 members in it, most of them being related in ...

Aztec Culture
Aztec Culture 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 l...

Galapagos
Galapagos I. First Reactions A. After I read Galapagos, I thought it was a good story. It was a little different from other novels I have read in that the author, Kurt Vonnegut, had a different style than most other authors. I liked how he made comments about humans' ?big brains? that always gave them foolish or reckless ideas that almost always had negative results. The way he showed how a world changed because people no longer thought that paper money was valuable provoked many thoughts about...

Landslides
Landslides Causing $1-2 billion in damages and more than 25 deaths per year, landslides are a major geologic hazard, caused by earthquakes and floods. Although, landslides are generally not as exciting or costly as earthquakes, major floods, tropical storms, and other natural disasters, they occur in more expanded places and may cause more property damage than any other geologic hazards. A wide variety of ground movements, such as rock falls, slope failure, and shallow debris flows can classify ...

Acid Rain
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 ...

Earthquakes
Earthquakes EARTH QUAKE REFERENCE FILES EARTHQUAKE REFERENCE FILES Earthquake, shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. Earthquakes occur when energy stored within the earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to the surface of the earth by earthquake waves. The study of earthquakes and the waves they create is called seismology. Scientists who study earthquakes are called seismologists. (Webster'...

Kilauea
Kilauea Kristin Laske Science-2 2/14/00 Kilauea Hawaii consists of a string of islands, or an archapelago. Kilauea is located on one of these islands, the central Hawaii island. Kilauea is one of the world's most active volcanic craters. Craters are formed either by the massive collapse of material during volcanic activity, by unusually violent explosions, or later by erosion during dormancy (Comptons). It is situated on the southeastern slope of the great volcanic mountain Mauna Loa. Its elevat...

Sources Of Energy
Sources Of Energy Sources of Energy Have you ever thought about how we get the energy to run the things we take for granite every single day. There are many sources of energy that that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is closely linked to the availability of energy in useful forms. The seven main energy sources are fossil fuels, hydroelectric, solar power, win power, geothermal, nuclear power, and b...

The Principle Events In The Evolution Of The Earth
The Principle Events In The Evolution Of The Earth The Principle Events in the Evolution of the Earth's Atmosphere The literal translation of the word atmosphere is sphere of vapors. The Earth's atmosphere is a protective sphere of vapors, or air that surrounds the Earth and provides it with a layer of insulation from the harmful rays of the sun. It is a vital part of the Earth, and has changed dramatically since the beginning of time. The earth's atmosphere has gradually changed since the Earth...

Valcanoes
Valcanoes The distructive power of a valcano is one of the most violent and deadly of all natural forces. In a short period of time, these massive explosions of the earth's crust can shatter whole communities. Valcanoes are very distructive no matter how big or how small they erupt at. They cause the highest amount of deaths and the greatest amount of damage. Of the two major types of Volcanoes, andestic and basaltic, the two typical volcanoes begin life when a mass of low-density magma forces i...

What Is Darwins Theory?
What is Darwin's Theory? Many scientists have different understandings and uses of bioengineering. Darwin's Theory on natural selection has stirred up some controversies on whether or not to remain studying and researching for information on the theory. Jeremy Rifkin, a philosopher and environmental activist, portrays in his article the world will be coming to an end if we remain to use bioengineering the way that we have been. He feels it is a waste of time and money to keep researching on Darw...

The Theory Of Evolution
The Theory of Evolution The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a warm warm little pond and that it took billions of years for the present diversity of living things to evolve. At the time, it was thoug...

Earthquake
Earthquake What is an Earthquake? An earthquake is a shaking of the ground caused by the sudden shifting of large sections of the earth's crust. Earthquakes are one of the most powerful events on earth, and they can be terrifying. A severe earthquake may release energy 10,000 times as great as that of the first atomic bomb. Rock movements during an earthquake can make rivers change their direction. Earthquakes can trigger landslides and Volcanoes that cause great damage and loss of life. Large e...

Exploring Mars
Exploring Mars MARS SURFACE EXPLORATION One question that is being asked by people is, Why go to Mars? The reasons are very simple. People want to gain recognition of how they were the first people who went to Mars and opened up a whole new world and most importantly to move forward in economics. As humans waste the precious materials and resources found on this planet we have to consider going to other planets to explore for materials and energy resources. Mars would be the first area for ind...

Mars Polar Landing
Mars Polar Landing A momentous occasion has been bestowed upon us. The Mars Polar Lander will try to reach its destination of Mars' southern polar ice cap. The Lander was presumed to touch down on Friday December 3, 1999. It was launched from Cape Canaveral Air Force Station Space Launch Complex 17 on January 3, 1999 and hopefully it has finally reached the surfaces of Mars. This mission is worth $327.6 million total for both orbiter and Lander (not including Deep Space 2). Those figures come f...

Mars
Mars Mars is the fourth planet from the sun and orbits the sun at a distance of about 141 million mi. Mars is named for the Roman god of war because it appears fiery red in the earth's night sky. Mars is a small planet that has about half the diameter of Earth and about one-tenth Earth's mass. The force of gravity on the surface of Mars is about one-third of that on Earth. Mars has twice the diameter and twice the surface gravity of Earth's moon. The surface area of Mars is almost exactly the s...

Ozone Layer
Ozone Layer Some scientists have proclaimed that the human race is slowly depleting the layer of ozone which protects us from ultra violet light. In reality, humans have very little control of the world in which we live. Scientific evidence has shown that there is very little depletion in the ozone layer and the contributions the human race makes towards this depletion is and always will be insignificant compared to nature. The theories of the depletion and what it would cause are flawed and co...

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...

Dinosaurs Extinction
Dinosaurs Extinction The first question that must be posed when trying to crack the mystery of the mass extinction is to ask, throughout history were there any other occurences of this magnitude? The answer is a resounding yes. Altogether over time there has been about eight mass extinctions to large land dwelling vertebrates. The most recent was about ten thousand years ago, killing most of the giant mammals like mammoths, mastodons, super-large camels, saber-toothed tigers, and others (Bakker...

Dinosaurs
Dinosaurs Dinosaurs: How they became extinct Something happened 65 million years ago, at the end of the Cretaceous period, something so devastating that it altered the course of life on earth. It seems like it happened so sudden, as geologic time goes, that almost all the dinosaurs living on earth disappeared. So how did these dominant creatures just die off? Was it a slow extinction, or did it happen all of the sudden? These questions bring rise to many different beliefs on how the dinosaur di...
