Exploring the Yellowstone Supervolcano

Exploring the Yellowstone Supervolcano Theres a powerful and violent  menace lurking under northwestern Wyoming and southeastern Montana, one that has reshaped the landscape several times over the last several million years. Its called the Yellowstone Supervolcano and  the resulting geysers, bubbling mudpots, hot springs, and evidence of long-gone  volcanoes  make  Yellowstone National Park  a fascinating geologic wonderland. The official name for this region is the Yellowstone Caldera, and it spans an area about 72 by 55 kilometers (35 to 44 miles)  in the Rocky Mountains. The caldera has been  geologically active for  2.1 million years, periodically sending  lava  and  clouds of gas and dust into the atmosphere, and reshaping the landscape for hundreds of kilometers.   Yellowstone Caldera is among the  worlds largest such calderas. The caldera, its supervolcano, and the underlying magma chamber help geologists understand volcanism and is a prime place  to study first-hand the effects of hot-spot geology on the Earths surface. The History and Migration of the Yellowstone Caldera The Yellowstone Caldera is really the vent for a large plume of hot material that extends hundreds of kilometers down through Earths crust. The plume has persisted for at least 18 million years and is a region where molten rock from Earths mantle rises to the surface. The plume has remained relatively stable while the North American continent has passed over it. Geologists track  a series of calderas created by the plume. These calderas run from the east to northeast and follow the motion of the plate moves to the southwest. Yellowstone Park lies right in the middle of the modern caldera. The caldera experienced super-eruptions 2.1 and 1.3 million years ago, and then again about 630,000 years ago. Super-eruptions are massive ones, spreading clouds of ash and rock over thousands of square kilometers of the landscape. Compared to those, smaller eruptions and the hot-spot activity Yellowstone exhibits  today are relatively minor. The Yellowstone Caldera Magma Chamber The plume that feeds the Yellowstone Caldera moves through a magma chamber some 80 kilometers (47 miles) long and 20 km (12 miles) wide. It is filled with molten rock that, for the moment, lies fairly quietly below Earths surface, although from time to time, the movement of the lava inside the chamber triggers earthquakes. Heat from the plume creates  the geysers (which shoot superheated water into the air from underground), hot springs, and mudpots scattered throughout the region. Heat and pressure from the magma chamber is slowly increasing the height of the Yellowstone Plateau, which has been rising more rapidly in recent times. So far, however, there is no indication that a volcanic eruption is about to occur. Of more concern to scientists studying the region is the danger of hydrothermal explosions in between major super-eruptions. These are outbursts caused when underground systems of superheated water are disturbed by earthquakes. Even earthquakes at a great distance can affect the magma chamber.   Will Yellowstone Erupt Again? Sensational stories crop up every few years suggesting that Yellowstone is about to blow again. Based on detailed observations of the earthquakes that occur locally, geologists are sure that it will erupt again, but probably not  anytime soon. The region  has been fairly inactive for the past 70,000 years and the best guess is that  will remain quiet for thousands more.  But make no mistake about it, a Yellowstone super-eruption will happen again, and when it does, it will be a catastrophic mess. What Happens During a Super-Eruption? Within the park itself, lava flows from one or more volcanic sites would likely cover  much of the landscape, but the bigger worry is ash clouds blowing away from the site of the eruption. Wind would blow the ash as far as 800 kilometers (497 miles), eventually blanketing the mid-section of the U.S. with layers of ash and devastating the nations central breadbasket region. Other states would see a dusting of ash, depending on their proximity to the eruption. While its not likely that all life on earth would be destroyed, it would definitely be affected by the clouds of ash and the massive release of  greenhouse gases. On a planet where the climate is already altering rapidly, a additional discharge would likely change growing patterns, shorten growing seasons, and lead to fewer sources of food for all of Earths life. The U.S. Geological Survey maintains a close watch on the Yellowstone Caldera. Earthquakes, small hydrothermal events, even a slight change in the eruptions of Old Faithful (Yellowstones famous geyser), provide clues to changes deep underground. If magma starts to move in ways that indicate an eruption, the Yellowstone Volcano Observatory will be the first to alert surrounding populations.

Consumer behaviour - Case Study Example Situational analysis on the company is conducted to determine the strengths, weaknesses, opportunities and threats which used as a basis of formulating the various alternative strategies for addressing the underlying issue. The best option is selected for the implementation and this option is cost effective and has significant favorable effects to the company. Problem statement Levi Strauss & Co. is a giant apparel company based in San Francisco and it is privately by the Levis for the last 147 years which has been marked by the years of success characterized with increased profits and the overall sale of its cloth wears. Levi Strauss is an all American brand and that its corporate image among the potential and the existing customers has a higher level of publicity. Therefore the goals and the objectives of this giant apparel cloth wear company for the last few years is to constantly sustain their increased sales and profitability, maintain its market share, consistently develop new products that is available to the existing and the emerging market segments through regular company research and development and finally is to consolidate its customer base by maintaining customers loyalty and satisfaction. Unfortunately Levi Strauss & Co in the recently over a period of time has become difficult in meeting these goals and objectives. Notably this trend has been attributed by the consumer changes in the cloth ware and apparel industry where there is frequent changes in fashion and designs thus affecting the changes and preference of the consumers across the entire market segment (Stamatiadis 2009). The key move that Levi Strauss & Co did not take keenly in during this period of fashion change and designs of the clothing wear in this industry is the failure to make changes according to the changes in the taste and preference of their existing customers thus contributing to Levi Strauss & Co being always seasons behind in terms of the emerging trends and designs hence their major competitors. More important is that they have not been able to sustain the market segment that comprises the young comprising of the under twenty five and the kids who have perceive that the Levi’s styles are too tight and they are suitable for the old generation thus resulting into the loss of the market share in which the younger generation has been Levi Strauss & Co major existing customers. One of the major setbacks is the failure to consolidate the younger generation who have been contributing more to their profits (Stamatiadis 2009). These emerging issues has resulted into the company realizing little success in its operations and the overall revenue generation and the loss of the customers and the reduced market share in the cloth wear industry, the changes in the consumer behavior in due to change in their taste and preference has resulted into their competitors such as JNCO, Old Navy and Kirkwear having an added advantage over them this resulting into th e loss of market share from 31% to 17% despite increase in the market of jeans wear and the overall cloth wear in a span of three years. The implication of these problems to Levi Strauss & Co include tumbling sales due to the loss of market share and the existing customers, layoffs of the employees where they reduced the number of employees by 40% laying off over 15000 total number of employees, plant closings due to the reduced sales and the loss of t

Rhetorical Appeals in Editorials - Essay Example Although the hospitals have their emergency rules as well as total accord privacy to the woman especially since she is in labor-men would feel that they are left out that most laws favor women. Another instance of pathos occurs when the author empathizes with the estranged ex-fiancà ©e, arguing that it would be embarrassing to have a man with whom they have separated being forced to watch her as she goes through the pain of childbirth. Not only would this embarrass her, but it would also remind her of their intimate moments before they broke up. Reference to intimacy is another use of pathos (emotional appeal of the reader). Use of ethos occurs since the guest blogger works for a reputable publisher-the Los Angeles Times. The news agency is a reputable newsroom and people would easily believe the credibility and accuracy of the publications (Behrens & Leonard 27). This makes the whole story believable and very appealing to the readership. Use of logos occurs when the author mentions that devoid of emotions and blame-game, it is always the right of hospital management to reserve the right of entry into hospitals. Fathers are always required to wait outside, not to be in the maternity room. Common sense demands that hospital patients’ feelings are respected. Logic would require that as a father, Plotnick is present during birth because he is the father of the unborn baby (Behrens & Leonard 81). This is an example of logos. Use of logos occur when the author argues that the case should have been dismissed; that in fact, there was no need to file a case since the laws are clear: hospital privacy laws deal with communications and records and gives the patient an upper hand (in this case the pregnant woman) as regards their absolute privacy.

Frankenstein | Feminist Interpretation

Frankenstein | Feminist Interpretation In most 18th century stories, men portray to be the more dominate figure in the story or family. Women in the stories tend to be less important than the males. In Mary Shelleys Frankenstein: or, The Modern Prometheus, women are mention that much and even if they are, they end up being killed or dying. Feminist interpreters tend to think Shelley has patriarchal man-centered views regarding gender roles. The idea of inactive women in a patriarchal society tremendously impacts the scheme of the novel. This is a complicated topic because most of her women characters are quiet, content women who, at first, share little similarities with self-confident women. Women did not have many rights as men and they could not stand up for themselves. If a woman were to do so they would be label as impertinent and unthankful. Shelleys approach on women is more complex than what we know it. She reveals to us that women are ambiguous and conflicting people, without a vast amount of control. Shelley reve als the injustice discreetly all through the book. All through the novel, Mary Shelley suggests that women are victims in a patriarchal world. In Frankenstein: or, The Modern Prometheus, Caroline Beaufort Frankenstein, Justine Moritz, and Elizabeth Lavenza are examples victims of a patriarchal world, dominated by men Caroline Beaufort Frankenstein, Victors mother is a victim in a patriarchal world. After her fathers death, Caroline is taken in by, and later marries, Alphonse Frankenstein. She ends up marrying Alphonse, a friend of her father. Alphonse later became her protector, he came like a protecting spirit to the poor girl, who committed herself to his care; and after the interment of his friend he conducted her to Geneva and placed her under the protection of a relation. Two years after this event Caroline became his wife (18). Alphonse is the dominate figure over Caroline, he is her protector. This shows women, like Caroline are not capable of taking care of themselves. In chapter 1, Shelley portrayal of Alphonses care for Caroline sounds as if she is in charge, Everything was made to yield to her wishes and her convenience (19). This short description shows that Caroline is cherished by Alphonse, making her more dominate. Shelley tells how Alphonse, strove to shelter her, as a fair exotic is sheltered by the gardener, from every rougher wind and to surround her with all that could tend to excite pleasurable emotion in her soft and benevolent mind (19). Shelley seems to portray women as a delicate person they needs to be care for by a man. Women, like Caroline appears to being incapable of taking care of themselves. This implies that women are victims in a patriarchal society, dominated by men. Justine Moritz lives with the Frankenstein family as their servant after her mother pass away. She is a victim in a patriarchal world, dominated by men. After William is murdered, the creature puts an image of Caroline, Williams mother, that William was carrying in Justines pocket and she is blame of murder. She later confesses wrongly to the crime out of trepidation of going to Hell. Victor did not believe that she has murder William saying, Justine Moritz! Poor, poor girl, is she the accused? But it is wrongfully; everyone knows that; no one believes it surely, Ernest? (62). Even after this she is still guilty of the murder and is executed. This reveals that Justine is a victim because even though she did not actually murder William, she was found guilty. The murdered was actually a male, the creature, yet Justine was punished. She is wrongfully executed for an action of a man. Justine is an innocent girl; she would rather face the consequences of a murder conviction than be excomm unicated by the church. Justine, a pure innocent soul, has no one defend her in trial. Yet, when Victor, a men, accused of killing Henry Clerval, has many people to defend him, a much more corrupt soul. For this reason Justine is put to death, therefore she is also a victim of a male dominate world. Elizabeth Lavenza is an example of women being victims in a male dominated world. Elizabeth is an orphan taken in by Victors parents. She is passive, waiting for Victors return. She is a victim is a mans whole because all she does majority of the time in the novel is wait for him to return. After receiving the news that Victor has fallen deeply ill she immediately writes him a letter, My dear Friend, It gave me the greatest please to receive a letter from my uncleà ¢Ã¢â€š ¬Ã‚ ¦my poor cousin, how much you must have suffered! I expect to see you looking even more ill than when you quitted Genevaà ¢Ã¢â€š ¬Ã‚ ¦My uncle will send me news of your health, and if I see but one smile on your lips when we meet, occasioned by this or any other excretion of mine, I shall need no other happiness (165-166). Elizabeth seems obsess with Victor, Shelleys portrayal of her seems to be as if she is in need of Victor, as if she would die without him. Elizabeth models the Victorian angel in the house. Victor describes her as a being heaven-sent. bearing a celestial stamp in all her features, fairer than pictured cherub (20). Victors description of Elizabeth makes us think that she is an angel. Victor is very fond of her, this show that Victor treasures her greatly, hence her being dominate over Victor for a moment. Victors action is the cause of Elizabeths death, because of the promise Victor broke to the creature he vows to take revenge on Victor. The creature ends up murdering Elizabeth on her honeymoon night with Victor. Even though at times Elizabeth appears to be dominating over Victor, he still surpasses and controls her, thus Elizabeth being a victim of a patriarchal world. Throughout the story Shelley suggests that women are victims in a patriarchal world, dominated by men. Frankenstein: or, The Modern Prometheus is an embodiment of Shelleys concern for feminine position and importance in the 18th century patriarchal society. Shelleys approach on women tells us that women are ambiguous and contradictory, lacking power. Shelley reveals the inequality inconspicuously all through the story. Throughout the novel, Mary Shelley suggests that women are victims in a patriarchal world. Caroline Beaufort Frankenstein, Justine Moritz, and Elizabeth Lavenza are victims of a patriarchal world, dominated by men. Men are the reasons why these women were punished. The novel exemplifies the unfairness of women in the 18th century and in the novel.

China Market: Analytical Report Essay

As we will be entering into the business world in China in the upcoming months, we have prepared a report on common business etiquette to be used when dealing with Chinese businesses. There are many ways in which we can unintentionally ruin relationships with China, so it is important to choose your words wisely. The following ideals will help us to present the company in a favorable light, and to avoid jeopardizing any potential relationships with Chinese businesses. According to Williams (n.d.), Before you approach a civilian of china, be prepared to do the proper greeting first. Proper greetings in china are generally a smile, good eye contact, politeness and a proper bow. The deeper the bow is, the more respect the Chinese believe you possess towards your acquaintance. These are considered a means of sincerity in their culture which will allow you to engage in further discussion with the business people you are making business with. Avoid informal greetings like â€Å"Hey, how are you?† instead use a formal greeting like â€Å"How do you do?† or â€Å"Glad to see you† as they seem like improper and disrespectful in their culture. When referring to someone of importance in China, you usually use their professional title rather than a Mr. or Miss. For example, use Chairman Freeman, rather than Mr. Freeman. This is important because it addresses your target with respect and shows that you acknowledge his or her position in the company. (Executive Planet. China n.d.). Typically, before any serious business discussion can happen, casual conversation is encouraged to relate to the person to whom you are writing. Good topics to include are those through which you can relate, such as the  weather, climate, and the geography of China. (Leung, 2008, p.21). Educating yourself on these subjects beforehand is very effective, as it will reflect well to your recipient that you have a good initiative in learning more about Chinese culture. However, there are some subjects to avoid discussing such as the history of China and Taiwan territory. (Executive Planet. China n.d.). Williams (n.d). has stated do not try to mention nor talk about religion in china. Even though China does have some basic religions like Buddhism, Confucianism, and Taoism, they do not worship as much as other countries do such as the USA and Japan. It is important to respect their culture and not engage in a conversation which would include speaking about their religion in any way. If you go out to eat at a restaurant with a possible customer or future employee whom is Chinese, there are some table manners that differ from that of westerners. For instance, a round table is more popular than the basic square table which is known in the western hemisphere. Make sure that the guest of honor is always seated to the right of the host (I.E. the employer or employee). Make sure you seat your guests and invite them to enjoy their meal and sitting the guests next the where the dishes are is disrespectful. Serving soda while on a business meeting is considered disrespectful to your guests. Ensure that you serve something more elegant like tea or distilled water, with the occasional beer and it’s important that you pour all your guests a cup of tea as it is not expected of the guest to pour their own tea.(Williams n.d). When writing the sales letter you should stay away from using colors because they can send a negative message. (Cimasko, 2010). It is important to make sure you keep your sentences short and concise and avoid using slang. It’s important to bring a minimum of at least 20 copies of your sales letter as it shows that you are well prepared. (Executive Planet. China n.d.). When it comes to composing your sales letter, it is more common to take the indirect approach. For example; in the Chinese culture, it’s more respectful  to use the words try or maybe instead of directly saying no. (Cimasko, 2010). Since the Chinese typically do not trust outside information you really must convince them that making business with your company would be in their best interest. Keep in mind not to offend anyone in your letter because embarrassment of a potential business partner would mean loss of that business. (Executive Planet. China n.d.). Recommendation Focus on how the job would be useful in China and avoid using slang or big words that would confuse our potential partners. Don’t make the sales letter too flamboyant or colorful because that might seem disrespectful. Resources De’Edra Williams. China.

Effects Of Social Networking On The Internet - 3661 Words

Do you recall your way of living preceding the invention of the Internet? Can you remember how you drew out necessary information concerning studies, weather patterns, or directions? More pressing, how did you have access to the where-abouts and status’ of your closest four hundred friends? While social networking has become an essential tool in modern day life, our dependence on the Internet has proven itself flawed in that it leads to the increase of adolescences’ diagnosed with depression. An ever increasing number of studies has examined this phenomenon in search of a correlation between social networking and depression in children maturing into adulthood. According to Guralnik (1984), depression is defined as â€Å"a psychoneurotic or psychotic disorder marked especially by sadness, inactivity, difficulty in thinking and concentration, a significant increase or decrease in appetite and time spent sleeping, feelings of dejection and hopelessness, and sometimes suic idal tendencies.† (p.395). A social network is an online interaction service which manages to construct communities and connect them with shared interests (Boyd Ellison, 2007). Social networking sites such as Tumblr, Facebook, and Twitter attract millions of users who have incorporated these networks into their daily practices.

Mineral Acid Definition and List

A mineral acid or inorganic acid is any acid derived from an inorganic compound that dissociates to produce hydrogen ions (H) in water. Mineral acids are highly soluble in water but tend to be insoluble in organic solvents. The inorganic acids are corrosive. Mineral Acids The mineral acids include the  bench acids—hydrochloric acid, sulfuric acid, and nitric acid—so-called because they are the acids most commonly used in a laboratory setting. A list of the mineral acids includes: Hydrochloric acid:  HClNitric acid:  HNO3Phosphoric acid:  H3PO4Sulfuric acid:  H2SO4Boric acid:  H3BO3Hydrofluoric acid:  HFHydrobromic acid:  HBrPerchloric acid:  HClO4Hydroiodic acid:  HI
