Article Summary of What Lies Beneath in America? USArray is a huge seismology project. The purpose is to basically take an ultrasound of the contiguous United States to understand the past and possibly the future of what goes on underneath the surface. Our current picture is mostly blurry, full of educated guesses and theories. By capturing all the sounds underneath and on the earth’s surface, a 3D picture will emerge that will clear the picture for us dramatically. We will be able to see what goes on underground all the way to where the mantle touches the core, maybe even further (Courtland, 2009).
The project consists of 400 seismometers that are buried underground in a remote, quiet place for 2 years, power by the sun. The seismological readings are continuously being relayed by satellite to a center in Seattle. These seismometers are about 70 kilometers apart. After 2 years, they get pulled and buried again more eastward eventually reading the entire contiguous states. After many years, we get have a clear picture of what goes on underneath. A total of 1624 sites are planned (Courtland, 2009).
2004 in California was the beginning of the project. During the writing of Courtland’s article, it was covering the Rocky Mountains. The plan moves eastward covering the entire vertical area as it moves along. While covering the Rocky Mountains, it
• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.
1. During the rise up between the North and South a new movement formed in the South, and it was the white supremacists movement. This movement stemmed from one issue that dominated decades of American history, slavery. The book Becoming America and our reader comes to terms with trials and tribulations of this time and the strain it put on connections among the nation.
The series Untold America: Divided Chicago delves into the issues surrounding urban poverty in Chicago. It showcases various community members from public school students, to school district administrators, and other community organizers. Overall, it offers a credible and realistic analysis of some of the problems in Chicago and also provides insight on the ongoing work to alleviate and solve them.
What is interesting about this paper is the author’s purpose. It seems as though he is attempting to raise awareness and support geophysics. However, all the points he brings up to discuss he quickly refutes with dangers. This confuses the reader as the article is more intimidating rather than informational. The overwhelming sense of danger associated with each
By 1600, England’s feudal system was nearing extinction, as a new family (Tudor’s) came to power and wanted support from the middleclass and the establishment of new liberties for Englishman (i.e. trial by jury and no arrest without a warrant), which resulted in a large amount of local and self initiative to prosper in the community: yet many beggars now existed, culminating in an increased need for colonial expansion both for personal prosperity and more space for the existing population.
Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.
The supervolcano in Yellowstone had an earthquake swarm that hit more than 1,200 events. Most park roads in yellowstone are closed for the season because of safety precaution this event and there are currently 1,284 tremors. Together with frequent earthquakes, vigorous hydrothermal activity, and abundant emissions of volcanic gases, relatively slow movements of the ground surface attest to ongoing activity in the vast magmatic-tectonic system beneath Yellowstone National Park. Imperceptible to the naked eye, episodes of uplift, subsidence, and stretching or contraction of the surface are monitored by repeated surveys and networks of sensitive instruments operated by YVO and its partners. Yellowstone is one of the most seismically active areas
Over the past few weeks of class, we have covered the first five chapters of our textbook, written by George Brown Tindell and David Emory Shi called, “America, A Narrative History.” Each chapter told the reader a narration of the history of America, as opposed to an expository version of America’s history. Each chapter had its own main idea over a portion of history, along with many details that cover the importance of the main idea. As a reader, one may obtain a deeper appreciation for the country 's history, prior to entering the class on the first day. The most important aspect of history, besides the battles that are fought, is the different cultures that make up today’s modern America.
The job of a President should not be taken lightly. The behavior of the political opponents is a disgrace. Donald Trumps goes against everything American. Everybody has there own opinion on who they believe should be President, so mine is it should be based off there success and what they want to improve, change and everyone benefits from the decision. It's not a game everyone's lives are at state.
The earthquakes above give a brief glimpse into the importance of analyzing past and present fault configurations. If scientists could make a breakthrough in this area perhaps we could better predict earthquake activity and better prepare ourselves if it is deemed a potential disaster is looming.
Two of Dr. Chafes primary points were that individualism challenged the normal and Christianity was practiced once a week worship. For entrepreneurs, individualism meant that one could begin to explore their own individual aspirations and be creative with no limits. “The natural result of individualism is innovation. It’s led to an invention, agricultural revolution, the industrial revolution, and affordable necessities and luxuries. None of this would have been possible if individuals weren't encouraged to think independently and create new things and keep some of the wealth from what they built” (Abbo, 2015).
In the book Rereading America, written by Gary Colombo, Robert Cullen, and Bonnie Lisle, the introduction of the book discusses how college students face different situations and have more control with one’s own actions. College typically have more workload and sometimes, that much work could impact a student’s quality of work. Students may rethink about their old habits and would have to readjust them to fit this new college life to become a critical thinker. In order to think critically, one must learn different perspectives and understand them. This is difficult because it requires a person to think deeply about things they wouldn’t previously think about and to see the world in multiple viewpoints.
This allows geologists to study what’s happening and how geological processes work and progress through time.
The earthquake was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada, an area of approximately 200,000 square miles. The ground motion caused by the earthquake source is recorded by instruments called seismographs. The zigzag trace made by a seismograph, called a "seismogram," reflects the changing amplitude and frequency content of the ground shaking beneath the instrument (usgs.gov). Using seismograms, scientists can determine the time, the epicenter, the depth, and the type of faulting of an earthquake as well as estimate how much energy was released by it.
The textbook, Portrait of America: Volume 2, 10th Edition, organized by co-authors, Stephen B. Oates and Charles J. Errico, is supplied with various historical topics written by different, credible authors. The textbook is, indeed, worth the time to read and understand. The authors express historical people and events many people have heard of, and expands the reader’s mind with personal stories and unconventional facts, one has not heard of. Most textbooks offer concise information about a person or event; Portrait of America authors take an unorthodox approach by stating information as well as revealing their own perspective on the topic. Such a technique as this is unfamiliar to the average student. Though an unconventional method, the authors are most effective at distributing information to the reader. Topics covered such as presidents, women, and events that changed America hold significance to the theory, Portrait of America authors take an idiosyncratic yet superb approach to delivering information to the reader.
