Earthquake -Shake, Rattle, & Roll

...“Earthquake - Shake, Rattle, & Roll” Submitted by: Dana Peebles For Instructor: Stephen Underwood July 14, 2014 PHSC 210-A02 Liberty University Online Elements of Earth Science   I. Introduction Music can be calming and even sometimes relaxing. However, the only music that might describe an earthquake, would be the song “Shake, Rattle, and Roll”. The very nature of earthquakes cause us to get anxious, and there is nothing calming about the “earth moving under your feet.” In this short report, I will be giving a general overview of how earthquakes are formed and what causes them. I will also discuss the methods that seismologist use to study these occurrences. As humans, curiosity can get the best of us. This curiosity causes us to ask questions and seek further discoveries as to why these events happen. In addition, I will also talk about the new inquiries concerning earthquakes and what leads up to these questions that may still be unanswered. II. General Overview To understand how earthquakes form, what causes them, and the components that make it up, one must know exactly what an earthquake is. Webster’s Dictionary states that an earthquake is the “shaking or trembling of the earth that is volcanic or tectonic in origin.” While this describes the movement and the cause, it doesn’t describe why. Earthquakes happen when the underground rock immediately burst against the fault. This activity causes seismic waves that travel along the earth’s......

Earthquake

...Earthquake From Wikipedia, the free encyclopedia This article is about the natural seismic phenomenon. For other uses, see Earthquake (disambiguation). [pic] An earthquake (also known as a quake, tremor, temblor or seismic activity) is the result of a sudden release of energy in theEarth's crust that creates seismic waves. Earthquakes are measured with a seismometer; a device which also records is known as aseismograph. The moment magnitude (or the related and mostly obsolete Richter magnitude) of an earthquake is conventionally reported, with magnitude 3 or lower earthquakes being mostly imperceptible and magnitude 7 causing serious damage over large areas. Intensity of shaking is measured on the modified Mercalli scale. At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacing the ground. When a large earthquakeepicenter is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami. The shaking in earthquakes can also trigger landslides and occasionally volcanic activity. In its most generic sense, the word earthquake is used to describe any seismic event — whether a natural phenomenon or an event caused by humans — that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults, but also by volcanic activity, landslides, mine blasts, and nuclear experiments. An earthquake's point of initial rupture is called its focus orhypocenter. The term epicenter refers to the point......

Ancient Chinese Contributions

... 2 The Ancient Chinese culture was a very successful culture that created many inventions and contributed to the advancement of not only the Chinese civilization but also to the civilization of the world. According to Henry Sayre, the Qin Dynasty, which was said to exist from 221BCE until 206 BCE, was the first empire in China to rise to dominance; however, the Han Dynasty was given credit for the most Ancient Chinese contributions and inventions (Sayre, 2012). The Han Dynasty existed from 206 BCE until 220 CE, and during the Han Dynasty contributions and inventions by the Ancient Chinese included: the wheelbarrow, seismograph, paper, compass, map, glazed pottery, hot air balloons, and silk. While the Ancient Chinese made many contributions and inventions for the world, the four most useful are the wheelbarrow, the seismograph, paper, and the map.    Today the wheelbarrow is commonly used for farming, gardening, and construction work such as moving dirt, bricks, mulch. It is suitable for many jobs because it allows the weight of the contents to be evenly distributed between the wheel and the operator. For many of the same purposes as we use the wheelbarrow today, the Ancient Chinese invented the wheelbarrow. It served the purpose of transporting things from one place to another that could not easily be one with just one person alone. According to Jeff, the earliest form of the Chinese wheelbarrows was said to be invented by a famous prime minister of the time named......

Lorenzo in the Lige

...FINAL EXAM STUDENT’S MANE: LORENZO NICOLAS MBA OBAMA PROFFESOR’S NAME: NINA WALKER SCI110 STRAYER UNIVERISTY March 19, 2014 1. There are two types of weathering. The first is mechanical weathering, the gradual breakdown of rock to sand, and then to silt, or powdered rock, and finally to clay through physical means. Mechanical weathering occurs in a variety of ways. For example, Heat and cold may cause minerals within a rock to expand and shrink at different rates, creating cracks. Water may seep into those cracks and freeze, expanding and splitting the rock. A raging river or ocean waves can smash rocks against each other, wearing the outsides smooth and turning rocks into sand. Or sand carried by the wind can act like sandpaper, slowly wearing rock away. A Glacier can rub debris against the rock beneath it, also acting like sandpaper. Even plants can force rocks to split as roots creep into cracks and grow. The second type of weathering is chemical Weathering, the breakup of rock caused by a change in its chemical makeup. Rain is the most common producer of chemicals that can weather rock. For example, Rain absorbs carbon dioxide and sulfur dioxide from the atmosphere, forming carbonic acid and sulfuric acid, two liquids capable of dissolving other materials. The levels of carbonic and sulfuric acids in rain, while generally weak, can over time dissolve rock such as limestone, freeing other types of rock. Over very long periods, rain can even dissolve enough......

Controversies Around Dam Reservoirs Benefits, Costs and Future

...Kołłątaja 1, 81-332 Gdynia, Poland 1University Abstract The paper reviews the social and environmental problems concerning the functioning of dams including their local and global effects. Particularly emphasized is a trend toward removing dams in many countries. These are issues of significant importance, particularly in view of the current discussions on justification of investing in new dams, and seeking safe and economical solutions for aging dams, risky in their further operation. Key words: dam building and removal, local and global effects. „Dams are both a blessing and a curse” Dr. Ute Collier 1. Introduction The above citation accurately, although briefly, reflects general perception of dams. On the one hand, they have undoubtedly played, and still play a significant role in the development of the civilization. On the other hand, their construction and functioning entail incurring immense social costs, often disproportionate to the resulting advantages. Dams have also caused vast irreversible damage in the natural environment. Therefore, there is growing opposition against constructing dams, and even demands to remove the already existing ones. This, in turn, leads to the mobilization of the hydrotechnicians’ circle, seeking possibilities for initiating new investments, which results in a larger and larger gap between the proponents and opponents of hydrotechnical structures on rivers. The objective of this paper is to discuss the social and environmental......

This energy crisis, along with economic growth and environmental stability must be sustained by developing alternative, renewable energy sources. Population is expanding at a geometric rate and each doubling will increase energy demand that will far exceed supply. China and India have recently developed into industrialized nations and several more will follow. Many leading scientists describe the “tipping point” for carbon dioxide emissions as having already passed, meaning it could be too late for renewable energy options to have an impact (McKibben, 2008). However, until the full impact is determined, scientists worldwide should be developing energy alternatives, in order to help stabilize the environment, secure national policy interests and boost to the economy. Geothermal energy represents a sizeable, renewable power source and is one of several alternative energy options that should be utilized. In order for this technology to be able to move forward with any success, it must achieve......
