...29th, 2012 Volcanoes A volcano is a landform that generally is circular in cross-section that is constructed from lava and tephra erupted onto the Earth’s surface, usually the crust. The opening through which the lava and tephra are emitted is called the volcanic vent. Lava is magma that reaches the Earth’s surface. Magma is melted rock at high pressure and temperature. Magma rises because it is initially less dense than the rock surrounding rock. It eventually equals the density of the surrounding rock and becomes a magma chamber. Tephra is pumice or ash that is blown into the air during eruptions. Volcanoes are generally found where tectonic plates converge and diverge; but are usually not created where tectonic plates slide past one another. As a result volcanoes can be found in all sorts of climate locations. There are four primary types of volcanoes which all have varying effects on the environment. This paper will explore these various types of volcanoes and show how they differ, as well as giving examples of eruptions for each of the types discussed. Principle Types of Volcanoes Cinder cones: Cinder cones are built from particles and blobs of congealed lava ejected from a single vent; they are the simplest forms of volcanoes. Gas charged lava is violently blown into the air and breaks up into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most of these types of volcanoes have a bowl shaped...

...were once all joined together in an ancient super continent called Pangaea. Land masses had drifted apart until they got to a certain position. Used 4 different pieces of evidence to help support his theory: 1. Continental Fit – If you placed certain continents together they look like they should/could have been joined together at some point. For example western seaboard of Africa and Eastern sea board of South America. 2. Geological Evidence – Rocks of similar type and age sharing the same formation can be found in South East Brazil and South Africa, which were believed to be joined. Also similar glacial deposits found in the Antarctica, South America and India. 3. Climatological Evidence – Similar coal deposits have been found in places such as Antarctica, North America and UK, all of similar age and all formed in tropical conditions. Neither of these places is still tropical therefore the coal must have drifted apart. 4. Biological Evidence – Fossil formations can be found on either side of the Atlantic. An example of this is the Mesosaurus, this reptile could not fly, however its fossils were found only in South America and South Africa. Therefore they must have been joined; otherwise the fossils would not be in the same place. * Paleomagnestism - The first piece of evidence to support Wegener’s Theory came from the discovery of a ridge of mountains running along the middle of the Atlantic Ocean known as the Mid Atlantic Ridge. 2 British Geologists, Vine and...

...Earth Science: Volcanoes Report by: Kenneth Ragragio What is Volcanoes? * Volcanoes are vents that allow lava, rock fragments and gases to escape from layers beneath the earth's surface. Learn how volcanoes form both on land and underwater and why they erupt. * Volcanoes are spectacular events and because of this, they have found their way into the plot of many Hollywood movies. While the movies have given most of us the vivid image of red-hot lava spewing out of the top of a towering volcano, they do not share the entire story of volcanoes Magma and Lava * So what exactly is a volcano? Well, it can be defined as a vent in the earth's crust through which lava, rock fragments, hot vapor and gases are ejected. In other words, a volcano is the earth's way of letting off a little steam. * The super-heated particles that eject out of a volcano come from deep below the earth's surface where temperatures can become so hot that rock actually melts. Magma is the term used to describe this hot molten rock from deep within the earth. * A volcano begins to form when magma, which is less dense than the rock it originated from, rises toward the earth's surface. This liquid rock collects in chambers called 'magma chambers,' where pressure builds due to expanding steam and gases associated with the magma. As pressure reaches a peak within these chambers, magma finds its way through a vent or fissure in the earth's surface, resulting in a volcanic eruption and the expulsion...

...sources. Small countries have a smaller need. They do not have as much capital, so they rely on the global superpowers. Renewable energy is the cleanest way to keep earth clean and free of pollution. Global powers have the resource to advance renewable energy quickly. They have professional people, machinery, technology, money know-how, etc. to make things happen. Different countries in different parts of the world use different kinds of renewable energy. Countries can share with other countries what they’ve learned. This is an effective way to increase renewable energy. The population of the world will greatly benefit from renewable energy. People will be healthier and pollution will be greatly decreased. There will be an ongoing supply of power for every facet of life. Renewable energy must be developed because nonrenewable energy is becoming expensive and environmentally damaging to retrieve. Renewable resources are constantly replenished and will never run out. A clean energy revolution is taking place among global super powers. This generates hundreds of billions in economic activity, and is expected to continue to grow rapidly in the coming years. This...

...silicate mantle and crust - which, along with surface water, made it different from the other planets in our Solar System. The formation of the early mantle was important as it consisted primarily of ferromagnesium silicate minerals, some of which contained water as an essential component (e.g. amphibole group minerals). Water-bearing magmas (molten rock) from deep in the lower mantle then rose towards the surface (being liquid, they were lighter than the surrounding solid rock) and emerged as volcanic eruptions. The Earth's atmosphere and hydrosphere developed from the degassing (loss of gaseous elements such as carbon, hydrogen and oxygen) of the early-formed core and mantle during this volcanic activity. In the present, abundant gases are still released from the Earth during volcanic eruptions and these are mainly composed of water (77%), carbon dioxide (12%), sulfur dioxide (7%), and nitrogen (3%), with minor amounts of hydrogen, carbon monoxide, sulfur, chlorine and argon. The Earth can be divided into two main parts. Atmosphere: measured from the surface of the Earth upwards to 150 km (anything above this is called space) Solid Earth: measured from the surface of the Earth downwards to the core The atmosphere The atmosphere makes up less than one millionth of the total mass of the Earth, and contains mainly nitrogen and oxygen (99% of the total) as gases. Other important components of the atmosphere are hydrogen, carbon dioxide, and inert gases such as argon and helium...

The landscape, for example, is bare and strange—though many consider it beautiful in its own way. Then, too, the far northern climate is not ideal for tourism. The winter weather is extremely severe and the summers are short and cool, with constant strong winds. The remote location also means that many products have to be imported and so they are expensive. However, the few tourists who do put up with these difficulties are warmly welcomed by the Icelanders. Is this a paragraph? _______ If it is a paragraph, what is it about? _____________________________________________ 2- For fewer tourists, lower prices, and more beautiful scenery, head for the Sagres Peninsula. The regional museum has a rich collection of costumes, weapons, and handicrafts. Buses will get you to most places, but for long trips, trains are cheaper and more comfortable.

Lutgens and Tarbuck Textbook: Earthquakes and Structures (Chapter 6) * Know the definition of an earthquake (pg. 190). --ground shaking caused by the sudden and rapid movement of one block of rock slipping past another along fractures in Earth’s crust called faults * Know the difference between the focus and epicenter of an earthquake. Which is located at the source of the earthquake? Which is located on the surface of the earth directly above the source? --Focus=Earthquakes tend to occur along preexisting faults where internal stresses have caused the crustal rocks to rupture or break into two or more units. The location where slippage begins is called the hypocenter, or focus. --Epicenter=The point on Earth’s surface directly above the hypocenter * Understand the concept of elastic rebound. What is it? How are earthquakes produced via elastic rebound? * --Elastic rebound=At some point, the stress along the fault overcomes the frictional resistance, and slip initiates. Slippage allows the deformed ( bent) rock to “ snap back” to its original, stress- free, shape; a series of earthquake waves radiate as it slides. Reid termed the “ spring-ing back” elastic rebound because the rock behaves elastically, much like a stretched rubber band does when it is released. * Know the three basic types of seismic waves...

...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...

...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 the realm of science. 11 Science, art, and religion can work very well together; like strings on a guitar, when played together, the chord they produce can be a chord of profound richness. 12 Science is concerned with gathering knowledge and organizing it. Technology lets humans use that knowledge for practical purposes, and it provides the instruments scientists need to conduct their...
