1. Cite the lines of evidence Alfred Wegener used to support his idea of continental drift. Why did scientists doubt that continents drifted?
Alfred Wegner’s evidence was the way the continents fit together like a jigsaw puzzle, fossils of the same prehistoric species were found where continental drift was expected to be (for example fossils of the same species were found in western Africa and South America), matching mountain ranges, and land features and climate change. His ideas were not accepted because Wegner could not give an explanation of what caused the continental drift.

2. Discuss the trade-off between money and human lives when considering construction in earthquake-prone zones. Consider factors such as housing costs, taxes for safer public facilities, different standards for different types of buildings (e.g., homes, apartments, stores and shopping centers, nuclear power plants, etc.).
Building in earthquake-prone zones can be costly as the codes for creating buildings that can withstand earthquakes changes almost yearly, and several factors outside of an earthquake can cause the building to fail and cost human lives. Most earthquake related deaths come from human construction failing and killing people in or near it. When building in these high risk zones, companies and the government must decide is it better to spend a lot of money on constructing building, roads, and bridges that can withstand an 8.0 magnitude earthquake where few have been but many smaller earthquakes are or where once in a great while an earthquake will occur. Higher cost in taxes, rent, and construction will save more lives but at a price. Cheaper solutions, mainly building for weaker earthquakes, will keep people safe, but at the cost of countless lives if a major earthquake were to hit.

...Medhurst General Purpose: To inform (Theory) Specific Purpose: My purpose is to inform my audience about the theory of Continental Drift. Central Idea: My central idea is making sure my audience has a better understanding of the Continental Drift and how the theory was formulated. The Continental Drift Theory` I.(Introduction) For years scientists struggled to explain how similar rocks and fossils were found on continents that are far apart from each other. Until the 20th century when scientist Alfred Wegener's theory of Continental Drift was introduced. A. "Before Wegner introduced his theory it was thought that mountains formed because the Earth was cooling down, and in doing so contracted. This was believed to form wrinkles, or mountains, in the Earth's crust. Wegener suggested that mountains were formed when the edge of a drifting continent collided with another, causing it to crumple and fold". ("The Earth in the Universe,"1999) -BBC reference. 1. Alfred Wegner noticed that the continents seemed to fit together at the edge of their continental shelves . 2. He noticed this because he observed that continents in the Southern Hemisphere have similar rock and fossil patterns. B. He believed that the continents were all once apart of a large supercontinent called Pangea. II. Aside from fossils and rock patterns there were other observations that led to his theory. A. "Glacial till deposits in the Southern Hemisphere aided Wegners hypothesis".("The supporting...

The Summary of the Deep

...The summary of the Deep… Everyone used to think that the bottom floor was a mystery. Many scientists were baffled as how it looks like and the map details of it. In fact it was said that mars was more known than the ocean floors. It was not until German scientist Alfred Wegener came up with the idea after extensive research and travelling. He had finally collected enough samples to conclude that all dry lands were once one continent called Pangea. This continent broke up 200 millions years ago and drifted to their present positions. He reasoned that south America and Africa were once connected with many evidence to back up his theory he pointed out the ancient climate similarities, fossil evidence and similarity of rock structures. Years later this theory was finally accepted and Mateen de Wit an ecologists one of whom also found his theory to be correct as all the proofs of fossils and rocks in the ocean of south America and Africa shared some similarities. Also marine geologists Joe Cann, found this to be true from his findings regarding undulation of ocean floor from time to time. During the cold war, submarines were commonly used. By both the Americans and the Soviets, but in order for the submarines to travel safely through the unknown deep seas, a map of the ocean floor must be made to guide these submarines. So American oceanographer Bruce Heezen and Marie Tharp and others prepared maps of the ocean floor and the mid-atlantic ridge and rift system, a mountainous chain...

...features of the earth like Catastrophism, Uniformitarianism, the Contracting Earth Theory, the Land Bridges Theory, and the theory that Plate Tectonics Theory stemmed from, the Continental Drift Theory. In this essay, I will explain why Plate Tectonics was not widely accepted until 1968 and how the formation of the earth was explained before it. In the late 1700s, Georges Cuvier proposed a theory called Catastrophism which explains Earth’s features like mountains and volcanoes by summing it up to a series of catastrophes. The evidence for Catastrophism was legends...

Tectonic Hazards

...Option 1 – Tectonic Activity and Hazards What are tectonic hazards and what causes them? 1. Introduction Tectonic hazards have to be distinguished from tectonic events. Hazards tend to refer to those events or items that pose a threat to humans and their lifestyle. Therefore, a tectonic hazard is one which involves tectonic processes being hazardous to humans. In the first part of my essay I will be explaining exactly what is meant by tectonic processes and will be referring to the relatively new concept of Plate Tectonics which, although being presented as a theory in 1912 by Alfred Wegener, was not actually taken as the standard model until the late 1960’s and even then was being criticized by many learned scholars into the 1980’s. I will then explain what the main types of hazards are in tectonics, namely volcanoes (openings in the earth crust from which material from below the earth’s surface can be ejected) and earthquakes (movement in the earth’s crust that causes shaking of the ground above). However, there are many more hazards that can be associated with these two, namely tsunamis and from volcanoes, pyroclastic flows, lahars and volcanic gases. What causes these hazards should be explained in my explanation of plate tectonics. Throughout my assignment, I will be using many examples of tectonic hazards from around the globe, but will be focusing on certain case studies to try and explain exactly what causes tectonic hazards. I will be using the San Andreas Fault...

Yet when we recall the discussions we’ve had with colleagues about instructor’s manuals over the years, two unnerving comments stick with us: “I don’t find them much help”; and (even worse) “I never look at them.” And, if the truth be told, we were often the people making such points! With these statements in mind, we have done some serious soul-searching about the texts that so many teachers—ourselves...

...What Is LGBT? LGBT stands for lesbian, gay, bisexual and transgender and along with heterosexual they describe people's sexual orientation or gender identity. These terms are explained in more detail here. Lesbian A lesbian woman is one who is romantically, sexually and/or emotionally attracted to women. Many lesbians prefer to be called lesbian rather than gay. Gay A gay man is one who is romantically, sexually and/or emotionally attracted to men. The word gay can be used to refer generally to lesbian, gay and bisexual people but many women prefer to be called lesbian. Most gay people don't like to be referred to as homosexual because of the negative historical associations with the word and because the word gay better reflects their identity. Bisexual A bisexual person is someone who is romantically, sexually and/or emotionally attracted to people of both sexes. Transgender or Trans Is an umbrella term used to describe people whose gender identity (internal feeling of being male, female or transgender) and/or gender expression, differs from that usually associated with their birth sex. Not everyone whose appearance or behaviour is gender-atypical will identify as a transgender person. Many transgender people live part-time or full-time in another gender. Transgender people can identify as transsexual, transvestite or another gender identity. Gender Identity One's gender identity refers to whether one feels male, female or transgender (regardless of one's biological...

...C hapter Two: The Basics of Logical Reasoning The Logical Reasoning Section The focus of this book is on the Logical Reasoning section of the LSAT, and each Logical Reasoning section contains a total of 24 to 26 questions. Since you have thirty-five minutes to complete the section, you have an average of approximately one minute and twenty-five seconds to complete each question. Of course, the amount of time you spend on each question will vary with the difficulty of each question and the total number of questions per section. For virtually all students the time constraint is a major obstacle, and as we progress through this book we will discuss time management techniques as well as time-saving techniques that you can employ within the section. The Section Directions Each Logical Reasoning section is prefaced by the following directions: “The questions in this section are based on the reasoning contained in brief statements or passages. For some questions, more than one of the choices could conceivably answer the question. However, you are to choose the best answer; that is, the response that most accurately and completely answers the question. You should not make assumptions that are by commonsense standards implausible, superfluous, or incompatible with the passage. After you have chosen the best answer, blacken the corresponding space on your answer sheet.” On average, you have 1 minute and 25 seconds to complete each question. Because these directions precede...
