Planets And Solar System Essays - Astronomy, Planetary Science

Planets And Solar System Planets and Solar System The Planets and the Solar System Planets 2 A planet is a celestial body that revolves around a central star and does not shine by its own light (Grolier, 1992). The only planetary system that is known to man is our solar system. It is made up of nine planets which range in size and make-up. The nine major planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. There are also many other minor planets which are also in our solar system, but they are unimportant compared to the nine major planets. In this paper I will discuss the planets and how they are each unique. Mercury which is the planet that is closest to the sun is the first planet I will discuss. Mercury is the smallest of the inner planets. It is speculated that the heat from the sun made it impossible for the gases present to become part of the planetary formation. The surface of Mercury is extremely hot. It is approximately 470 degrees celsius on the surface and is thought to be even hotter at the two hot spots. These hot spots are on opposite ends of the equator. It is the heat of the surface that makes it impossible for Mercury to have any type of atmosphere. Mercury orbits the sun once every 88 days and has a true rotation period of 58.6 days. It is the closest planet to the sun and therefore orbits faster than any other planet (Thompson/Turk, 542, 1993). It is said that Mercury rotates three times for every two trips around the sun, so that during Planets 3 every alternate perihelon passage the same face points directly at the sun. Geologically, the most remarkable features of Mercury are compressional cliffs or faults, just the sort of wrinkles that might form in the crust if the interior of the planet shrank slightly (Morrison, 74, 1993). It is speculated that it was the solidification of Mercury's metallic core that caused this global shrinkage. Mercury is also . . . enriched in metal or depleted of rock (Morrison, 74, 1993). It is also believed that some of the inner core of Mercury is still in a fluid state. Scientists also believe that Mercury's surface is made partially of silicate rock. The best way to describe Mercury is, . . . small, heavily cratered and airless (Morrison, 71, 1993). Venus is the second closest planet to the sun and is said to . . . most closely resemble Earth in size, density, and distance from the sun (Thompson/Turk, 542, 1993). Venus is known to most scientists as the sister planet to the Earth. It is called this because it closely resembles the Earth's mass, density and diameter. The only thing different is that Venus is shrouded in thick clouds that completely hide the surface of the planet (Grolier, 1992). The surface temperature is also much warmer than that of Earth. Venus completes one revolution around the sun in 224.7 days. This makes the Venusian day equal to 117 earth days. It is thought that this slow rotation may be the reason why Venus has no magnetic field. Planets 4 The atmosphere of Venus made up of 98% carbon dioxide and 2% Nitrogen. This atmosphere also has the presence of helium, neon and argon. This is yet another thing which makes Venus different from Earth. The surface of Venus is quite a bit like that of the Earth. The surface has volcanoes and smooth plains. Much of the volcanic activity on Venus takes the form of Basaltic eruptions that inundate large ares, much as the mare volcanism flooded the impacted basins on the near side of the moon (Morrison, 93, 1993). One thing that differs from Earth is that there is no water liquid on the Venusian surface. Some of the scientific data that follows was taken out of Cattermole's book. The mean distance from the sun is 108.20 Km. The equatorial diameter is 12,012 Km and the equatorial rotation is 243 days. Finally the mass of Venus is 4.87*10^24 (Cattermole, 63, 1993). Venus, although different than Earth, is still our sister planet. Mars is the fourth furthest away from the sun and is recognized by its reddish color. Mars is also very much like the Earth. More than any other planet in the solar system, Mars has characteristics that make it an Earth-like world (Grolier, 1992). One thing that is very similar to Earth is the rotation period. Mars rotation period is only thirty seven minutes longer than the Earth's. This

Emerging Adults Essay Example

Emerging Adults Essay Example Emerging Adults Essay Emerging Adults Essay nonprofit), â€Å"The average student graduates with about $22,000 in debt. Generation Y uses their debt as a reason to delay working because they only want extremely high paying jobs. They believe that only the perfect job is good enough for them and are not willing to settle for anything less. Ironically, they also use their indebtedness as a reason to stay in school longer- in order to prepare themselves for higher paying jobs: In the 1970s, a bachelor’s degree could launch a career and support a family. Not anymore. Now, graduate school is almost a necessity, and that means greater expenses, often when students are already saddled with college loans. Financial independence is but a dream for many. (Jayson 85) In reality, this approach to life just postpones entering the workforce and growing up. The longer they stay in school, the longer they have to figure out what to do with their life. This gives them more time to just meander through life without making any difficult decisions. With the large amount of debt and the unwillingness to move on, these young adults choose to take their time when it comes making life decisions. Their attitudes are completely unrealistic. They are actually harming themselves by building up more debt and delaying entrance into the workforce. They think that whatever they want to accomplish can be done, even without hard work and effort. Another aspect of the economy that members of Generation Y use to prevent them from having to grow up is the struggling job market. The monthly U. S. Bureau of Labor Statistics â€Å"reports†¦that among all 20-24 year-olds the unemployment rate was 17. 2 percent in April† (Zappe). These â€Å"emerging adults† use this as a reason to just hang out and wait for the right job to come to them, instead of actually going out and finding work. These twenty-somethings are lazy and refuse to work hard in order to succeed. For example, â€Å"Many are increasingly declaring themselves unwilling to work more than 40 hours a week† (Warner 12). They only want jobs that fit into their schedules and ones that do not require hard work and long hours. They think that everything is just going to be handed to them. Jeff Arnett, a psychology professor at Clark University in Worcester says, â€Å"that young men and women are more self-focused than at any other time of life, less certain about the future, and yet also more optimistic, no matter what their economic background. † This optimism is a false sense of security. Because their parents have led them to believe that they are the centers of the universe, members of Generation Y focus only on themselves and, and the idea that eventually the universe will provide them with what they want; they will eventually find the perfect job, so there is no need to find one any time soon. This sense of idealism is reflected in the statistic that â€Å"over 90 percent think they have the perfect resume† (Warner 12). This overconfidence and sense of entitlement is how they rationalize not growing up. They believe that they are too good for most jobs- so much so that â€Å"41 percent of job seekers this year turned down offers† (Warner 12). The long path to adulthood that Generation Y is taking has significant negative effects on Generation X, their parents. Generation Y is still very dependent on their parents, even as 20 year olds. For one, â€Å"American parents give an average of 10 percent of their income to their 18- to 21-year-old children† (Henig 8). This means that the parents of Generation Y must work later into their lives to support their unemployed children. As Sharon Jayson points out, the term â€Å"boomerang kids† refers to those members of Generation Y that â€Å"return home after college. According to Twentysomething Inc. , a market researcher that tracks youth trends, 65% of this year’s grads expect to live with their parents after earning degrees† (86). These parents have worked their entire life to finally be able to retire and relax, but instead they â€Å"are helping pay bills they never counted on paying† and expenses that these twenty-somethings should be paying for themselves (Henig 10). The expectations that parents will take care of Generation Y because they do not want go out and find work or because they want to live at home â€Å"places a terrible burden on the parents who might be worrying about their own job security, trying to care for their aging parents or grieving as their retirement plans become more and more of a pipe dream† (Henig 11). 0 somethings parents have their own troubles to worry about and because Generation Y refuses to grow up, their own problems become even harder for them. Generation Y should be more considerate of their parents and understand that it is time to support themselves. 20 year-olds are taking advantage of their parents because they know how much their parents loved and wors hipped them as children. Most parents will always be there for their children, but the â€Å"emerging adults† should realize that it is time to give their parents a break, and finally become responsible for their own lives. Generation Y is now â€Å"emerging† into adulthood. Many of them, however, still refuse to grow up, rationalizing that they must take their time to examine all their options in order to find their perfect niche in this imperfect world. These young adults are lazy, overconfident, and self-indulgent. They believe that everything is just going to work out in the end for them, so hard work is not necessary. Not surprisingly, then, it is taking longer and longer for these twenty-somethings to finally figure it out. It is time for them to stop relying on their parents and to stop using today’s poor economic conditions as an excuse to delay becoming independent. It is time for the â€Å"emerging adults† to realize that their life is in their own hands and that in order to succeed they need to grow up and start taking responsibility for their own lives.

Achilles Tendon

The Achilles tendon is a tough band of threadlike tissue that connects the calf muscles to the heel bone. The Achilles tendon is also called the calcaneal tendon. The calf muscles unite into one band of tissue, which becomes the Achilles tendon at the low end of the calf. The Achilles tendon then inserts into the heel bone. Small sacs of fluid called bursa cushion the Achilles tendon at the heel. The Achilles tendon is the largest and strongest tendon in the body. When the calf on our toes when walking, running, or jumping. Despite its strength, the Achilles tendon is also vulnerable to injury, due to its limited blood supply and the high tensions placed on it. Achilles tendon injuries are common in people who participate in these sports such as running, gymnastics, dance, football, baseball, softball, basketball, tennis, and volleyball. An Achilles tendon injury might be caused by overuse. Stepping up your level of physical activity too quickly. Not stretching enough before exercise. Wearing high heels, which increase the stress on the tendon. Problems with the feet. An Achilles tendon injury can result from flat feet, also known as fallen arches. In this condition, the impact of a step causes the arch of your foot to collapse, stretching the muscles and tendons. Muscles or tendons in the leg that are too tight. Rest your Achilles tendon. Avoid all activities that strain the tendon, such as stair climbing or running. While allowing your tendon the days, weeks, or months it needs to heal, try other activities, such as  swimming. Reduce pain by icing your Achilles tendon and taking nonprescription pain relievers. Follow your physical therapy  program if one has been prescribed for you, and do gentle stretching and strengthening exercises, especially focusing on  calf stretches. Do not smoke or use other tobacco products. Smoking slows healing, because it decreases  blood supply. Wear footwear that protects the tendon while it is healing. Quality athletic shoes that support your arches and cushion your heels can make a big difference in your daily comfort and the healing process. If needed, talk to your physical therapist  about heel pads. A bandage that keeps your foot  flexed can restrict the motion of the Achilles tendon. A silicone sleeve or pad can distribute pressure on the Achilles tendon.

Psychology - Essay Example Similarly, significantly more women than men meet the diagnostic criteria for anxiety disorders (56% vs 35%). On the other hand, men (20%) are twice more prone to substance abuse disorders (eg. alcohol dependence) than women (8%) (WHO, 2007). Also, the incidence of antisocial personality disorder (psychopathy) is three times more in men than women. In cases of severe disorders as schizophrenia, it is obsevered that men have early onset of symptoms but women experience higher frequency of hallucinations or psychotic symptoms. The key reasons behind greater prevalance of such disorders in women are because of greater exposure to poverty, discrimination and socioeconomic disadvantage such as child/sex abuse, traditional gender based violence and overwork. Reasons why more men have antisocial personality disorders as women tend to be more empathic than men. Works Cited WHO. (2007). Gender Disparities in Mental Health.

Does Globalisation Americanisation Essay Example | Topics and Well Written Essays - 1250 words

Does Globalisation Americanisation - Essay Example Another feature of globalisation is grobalisation by which â€Å"the imperialistic ambitions of nations, corporations, organisations† (Ritzer & Ryan 2004: 41) promote the imposition of themselves in various geographic areas for increased power, influence and profits. Two subprocesses of grobalisation are Americanisation and McDonaldisation. Americanisation can be defined as the further spread and establishment of American ideas, customs, social patterns, language, industry, and capital around the world. The concept of Americanisation â€Å"envisions a growth in American influence in all realms throughout the world† (Ritzer & Ryan 2004: 47). McDonaldization is the spread of the fast-food restaurant concept not only within the United States, but in increasing numbers of other societies throughout the world (Ritzer 2010). Thesis Statement: The purpose of this paper is to determine whether globalisation is synonymous with Americanisation. The Emergence and Evolution of Amer icanisation and Globalisation Americanisation is the larger conceptual framework that includes various interconnected phenomena, among which globalisation is one of the most important. The cultural impact of globalisation on Americanisation as a key 20th century transformation has great consequences. Mennell (2009) believes that globalisation and Americanisation should be examined together in long term perspective. The United States drove globalisation from 1945 to 2000; during this time globalisation was synonymous with Americanisation and Westernization, although terms such as â€Å"hybridity† and â€Å"flexible acculturation† which pertain to immigrants in the United States, prevailed only after 2001 (Nederveen Pieterse 2009). Globalisation is radically transforming all nations and the lives of billions of people all over the world. Globalisation theory characteristically accorded a great deal of significance to developments in the west, and its western bias also me ant that â€Å"the rest of the world had little choice but to become like it† (Ritzer & Ryan 2004: 41). After the Second World War, American companies with a highly efficient industrial management system expanded to locations across the globe. This globalisation of American companies had an effect on the internationalisation of German firms between 1945 to the early 1970s, and the resultant outcomes on German corporate management and competitive strategies throws light on how global corporate players evolved. The Americans tried to recapture the markets that they lost during the war, and attempted to enter new geographic markets. To withstand the American challenge, German companies resorted to new management strategies such as the adoption of American know-how, leading to a process of catching up and globalised corporate growth in German companies (Hilger 2008). Conversi (2010) argues that the consequences of cultural Americanisation is one of the least studied areas of the phenomenon of globalisation, although it is the most critical feature. The global expansion of Americanisation can be denoted accurately through distinctive stages of expansion, followed by periods of comparative and momentary recession; this in turn is followed by increased expansion. Hence, Americanisation is the broader conceptual framework that consists of various interconnected phenomena, out of which the most important is globalisation. This has established

Primary Commodity Exports and Civil War Essay Example for Free

Primary Commodity Exports and Civil War Essay Fearon’s study particularly pertains to the evaluation on which particular countries are actually prone to undergoing situations such as civil wars. In this article, he along with his co-researchers found out certain elements that contribute to the increase of threat towards the possibility of a country undergoing a civil outburst. According to the said researchers, the most important issues that needs consideration on this part of the situation is the emergence of countries that are involved in primary commodity export appointments in the field of international trade. Apparently, it is in this article that poverty has been noted to be a reactive result of several globalization approaches which also brings about the possibility of social chaos giving way to civil war. The bridge that was supposed to keep nations together through globalization is now serving as the strongest reason of gap between people around the world and even within countries. The widening gap is also producing serious consequences for the richer nations. This is because of their growing dependence on the raw materials of the nations of the â€Å"Third World. † But now these nations have changed their attitudes about how their resources will be used, and paid for. An example of this was the action taken by the oil-producing underdeveloped nations, sending shock waves throughout the industrial lands. For many decades, the poorer oil-producing nations had to sell their oil at a relatively cheap price. Recently, these nations banded together and agreed to quadruple their prices. The poor nations have laid down a clear challenge to the rich nations. They will no longer passively accept what the industrial nations have assumed for more than two centuries. That assumption was that there would always be cheap raw materials available from the poor nations. No longer is this the case. However, the dilemma of the poor nations is that most of them are not blessed with abundant raw materials. Most of them lack abundant mineral and oil resources. They are largely agricultural lands, and in bad years, they have nothing to fall back on to sell to other nations. Therefore, they will not have the money to buy the food and other things they need to help them in bad years. That is just what is happening now to various countries in Africa, Asia and Latin America. The main idea of studying the way people live in the society is to see how far they have fared in making their way to progress. However, contrary to the aimed unified progress, development is usually shifted only to the â€Å"haves†. Yes, the world may be seemingly unfair, equality may even seem too impossible to be achieved, but through a unified effort, having an equal community could still be worked upon by the entire human civilization; something that is most needed to avoid possible outburst of civil war.

Thomas Jefferson :: History Historical Jefferson Essays

Thomas Jefferson â€Å"Thomas Jefferson still survives,† John Adams’ last words most definitely stand true, even today. Thomas Jefferson was a well-educated man with a wealthy and proper British-American upbringing. An excellent education was the beginning step to all the wonderful things Jefferson would do for our country. After college, he became a lawyer, and soon a member of the House of Burgesses. An intelligent writer and thinker, Jefferson, along with four others, was chosen to write the Declaration of Independence. Filled with Thomas Jefferson’s great ideas, the Declaration of Independence greatly influenced the Constitution.   Ã‚  Ã‚  Ã‚  Ã‚  After the Declaration of Independence was written, a fire sparked in the hearts of the Americans who had suffered from the King of England’s oppressive governing. A course of action had finally been taken against the King. New ideas spread regarding â€Å"life, liberty, and the pursuit of happiness.† The young nation’s hope of freedom was now becoming more of a reality than a dream.   Ã‚  Ã‚  Ã‚  Ã‚  In the years following, a Constitutional Convention was held in order to â€Å"form a more perfect union.† Models for the constitution consisted of forms of government such as the Magna Carta, which limited power of the king or government figure, and the Declaration of Independence. Ideas taken from the Declaration and Thomas Jefferson included points such as â€Å"We hold these truths to be self evident: that all men are created equal; that they are endowed by their Creator with certain inalienable rights, among these are life†¦Ã¢â‚¬ . By mentioning the truths that are self evident, Jefferson lets the colonists know that they do indeed have rights. The Declaration was used as a model for the Constitution, through its focus on equal rights, to remind us that all men are created equal, and should be treated with the basic respect human beings deserves, along with the right to choose our destiny.   Ã‚  Ã‚  Ã‚  Ã‚  Today, we know America as a nation of peace and refuge from the other tyrannous governments of the world. Once, our nation, as American colonies, experienced these same tyrannous behaviors from the distant King of England. Thomas Jefferson doesn’t hold back when mentioning the King’s unjust actions. As stated in the Declaration of Independence, †¦to a jurisdiction foreign to our constitution and unacknowledged by our laws , giving his assent to their acts of pretended legislation for quartering large bodies of armed troops among us, for protecting them by a mock trial for punishment†¦for cutting
