Examine the physical processes that cause tectonic hazards including plate boundaries and other factors
A range of case studies, scales and locations will be used to investigate physical causes of tectonic hazards. ’A natural hazard would be defined as a natural event that has the potential to threaten people’s lives and property’ Whittow 1980. Therefore, we could define a tectonic hazard as a geophysical process involving seismic activity and the movement of the earth’s plates, creating events such as earthquakes, tsunamis and volcanic eruptions. Physical processes that cause tectonic hazards including plate boundaries and other factors can be separated into 2 categories; these are primary and secondary hazards. A primary hazard is a hazard that came as a direct result of the tectonic activity, whereas a secondary hazard is a hazard which is created by primary hazards, these include tsunamis, lahars and aftershocks. The physical processes that cause tectonic hazards occur at plate boundaries. These plate boundaries are categories as: convergent (oceanic- continental), convergent (continental- continental), divergent (oceanic- oceanic), divergent (continental- continental), transform and collision zone. However these tectonic hazards do occur elsewhere as a result of intra-plate boundaries and hotspots. Other physical factors that cause tectonic hazards include relief of land, geology and aftershocks. Tectonic hazards revolve around the key idea of tectonic theory put forward by Holmes, Hess and Wegener. This is key to understanding and examining the physical processes that cause tectonic hazards as it is a central principle to the idea of plate...

...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......

Disaster Management

...Introduction Natural Hazard any natural event which has an adverse socio-economic impact on the human being. Alternatively, an extreme natural event, such as a cyclone, an earthquake or a flood, that is not caused by human beings. These are naturally occurring phenomena that only become hazardous due to the intervention of human infrastructure. The vulnerability of human infrastructure to destruction (risk) by a disaster is also an important factor in understanding natural hazards. The distribution and impact of natural hazards is unequal with greatest loss of life and property in the developing part of the world. This is not because of greater hazard frequency but simply because of greater vulnerability. Therefore, the people in the developing countries are at high risk than those of developed countries. Combining the risk factor the natural hazard can be defined as the probability of a change in the natural environment of a given magnitude occurring within specified time period in a given area while the associated risk is the consequent damage or loss of life, property and services. The frequency of major hazard appears to have increased since 1960 and the number of people killed each year has decreased at a rate of about 6% and the loss or property has also decreased steadily. This has taken place owing to increased awareness and better hazard management. The increase in the frequency of hazard can be assigned to such factors as better global news coverage, increasing......

Science society. The study of science and technology includes both processes and bodies of knowledge. Scientific processes are the ways scientists investigate and communicate about the natural world. The scientific body of knowledge includes concepts, principles, facts, laws, and theories about the way the world around us works. Technology includes the technological design process and the body of knowledge related to the study of tools and the effect of technology on society. Science and technology merge in the pursuit of knowledge and solutions to problems that require the application of scientific understanding and product design. Solving technological problems demands scientific knowledge while modern technologies make it possible to discover new scientific knowledge. In a world shaped by science and technology, it is important for students to learn how science and technology connect with the demands of society and the knowledge of all content areas. It is equally important that students are provided with learning experiences that integrate tools, knowledge, and processes of science and technology. The Science and Technology Standards outline the essential understandings of these disciplines. Standard A describes four themes that serve as a broad scaffold for understanding and organizing student understanding of the content and processes of science and technology. Standard B describes the processes of scientific inquiry and technological design. As a...

Answers to Conceptual Sciences

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses. They lie outside...

...Knowledge Area Module I: Principles of Societal Development Student: Michael Moore Program: PhD in Applied Management and Decision Sciences Specialization: Leadership and Organizational Change KAM Assessor: Dr. Javier Fadul Faculty Mentor: Dr. Javier Fadul Walden University February 5, 2011 ABSTRACT Breadth This Knowledge Area Module (KAM) broadens common knowledge of societal and cultural development by looking beyond economic and conflict theories for understanding other positions regarding social advancement. The Breadth Component studies societal and cultural development in terms of evolutionary, cyclical, and fundamentalist theories and demonstrates why it is important to looking beyond the popularly accepted knowledge about social development represented by economic and conflict theory. This approach provides a more robust generalization that more adequately describes social advancement, and concludes that classical researchers did not consider leadership as a social segment to be studied, that influences societal and cultural development. Leadership understanding of societal and cultural development is critical for enabling them to lead positive social change. ABSTRACT Depth The Depth section compares modern research in societal and cultural development to the theories of classical researchers in order to further develop the findings of the classical study, and to determine if......

...文勇的新托福精选阅读(原黄金29篇)真题[2010年4月3日 5.8版本] 俺常常收到同学们的邮件,要我推荐各种各样阅读材料,问我iBT的复习资料中 Barron, Longman, Delta等等哪个更好。我其实很无奈---因为尽管这些机构很大牌,但大牌丝毫都不意味着文章“质量高”(比如你可以想想三鹿奶粉)---说这些机构的文章质量不高,并不是说文字写得不好,而是说这些文章的句子结构, 论述方式, 出题思路与ETS的并不一致(有时候甚至大相径庭):用这样的材料训练,实在是 事倍功半。 于是,我们实在应该去找找由ETS出的iBT文章来做:(我们能够找到的|由ETS编纂的标准iBT文章有) 1. OG[1]之中的13篇文章[2];(其中3篇为第三版OG之中的文章) 2. 13次(套)TPO[3]之中的3*13=39篇文章[4]; 3. 早期[5]报名之时ETS赠送的3篇在线测试题 4. ETS官方给出的模考软件之中抽出的1篇文章; 于是这个文档在我的一时兴起之下,出现了: OG拿在手上,可以一个个字的敲成电子版;TPO的所有考试都是在自己的计算机进行,于是可以一边花钱参加考试,一边截图与录像---再利用截下来的图片,逐个的敲下来;早期的ETS赠送的3篇在线测试题,我也恰好有电子版本;官方的模考软件稍微用点功夫,就能将文章提取并复制出来。虽然工作有些繁杂,但总算完成了所有文章的敲打工作。再花了些时间,把这53篇文章都做了答案,附在文章的后面。(由于TPO之中有3篇文章与OG中完全重复,于是减去3篇,只剩下53篇。)同时我还更正了OG上几个明显的错误(详见文后附录)当然,我还做出了方便大家理解文章的参考译文,附在文章的后面。 在这53篇由ETS出的文章没有做完之前,我们实在不应该花时间在任何其他的题目之上。我有时候甚至会对着我的弟兄们高呼:“没有把这53篇做3遍,你好意思上考场么?你好意思花钱在任何一本垃圾书上面么?[6]” 另外,如果你正在准备iBT-SAT-GRE的作文部分或者写留学文书,也应该仔细的琢磨一下这些文章:经过ETS打磨的文章,无一不是精妙绝伦,极具模仿价值。常常有同学拜托我帮她(他)写PS,也说起自己的句子怎么看都像是小学生写的(尽管用上了GRE里面的单词),于是会随口问我“勇哥,您的写作能力是怎么训练出来的。”我说,“看呗,看呗:托福文章看多了,写作能力自然就提高了。” “这ETS的这些文章真的那么好?”。每当听到这个问题,我都会装做赵本山的样子来一句“谁用谁知道~~” 文勇 欢迎进行未删节的转载|且不必告诉我你转载到哪里去|都是一个战壕里面的弟兄啊… 告诉大家一个好消息,本文档中的TPO1-TPO9,以及在线测试题和官方模考题目的解析已经在市面上可以买到了!(好吧,我承认以下显然是广告部分): 这本《托福真题详解-阅读分卷-第一册》是给弟兄们现在市面上可以获得的TPO1-TPO9阅读部分的文章解析,题目解析,中文翻译和每篇文章的必备词汇:文章解析是为了让大家养成从整体抓文章结构的感觉,题目解析是为了使大家能够在做完题之后知道正确选项为什么对,错误选项为什么错——并且因此来培养良好的做题思路,中文翻译是为了帮助大家扫除那些自以为理解对但实际理解有误的句子,在每篇文章后面配上必备词汇无非是为了节省大家的一些查单词而已。 另外,这本书还包含了一张CD(我想你可能第一次听说阅读书...
