Volcanic eruptions both cool and heat the earth. When a volcano erupts, dust, ash, and sulfur are released into the atmosphere. Depending on how light the particles are, some will travel to the stratosphere while larger ones will fall to the earths surface. Don’t waste time! Our writers will create an original "How Volcanoes Influence Climate" essay for you Create order Small particles of dust and ash that remain in the stratosphere block the solar radiation hitting the earth, causing the planet to cool (How Volcanoes Influence Climate, 2018). Due to the circulation pattern in the stratosphere, dust and ash can travel worldwide to locations far from which they erupted. This can last from month to years, depending on how big the particles are. Sulfur is also ejected into the atmosphere after volcanic eruptions. Sulfur travels to the stratosphere, where it merges with water. Once sulfur and water fuse, sulfuric acid aerosols form and create tiny droplets that reflect solar radiation, cooling the earth even more (How Volcanoes Influence Climate, 2018). In contrast, volcanic eruptions can warm the earth by releasing large amounts of carbon dioxide, a gas that plays a major role in the greenhouse effect. These greenhouse gases play a role as an insulator, preventing large quantities of the warm gases to leave the earth. Volcanic eruptions generate 110 mi llion tons of carbon dioxide every year (How do volcanoes affect world climate?, 2005). The Tambora volcano eruption in 1815 in Indonesia shot volcanic columns up to 80,000 feet high, making it the largest eruption in world history. The volcano showed its immediate effects when the hot lava and pyroclastic flow killed 10,000 people (Ames, 2017). The volcano affected the climate, making it known as the year without summer. The Tambora volcano released so much ash and aerosol into the atmosphere that the sky became a darker color and blocked solar radiation from hitting the earth. The particles were so small that they were able to circulate through the stratosphere to other parts of the world. The planets temperature dropped 3 degrees celcius (How Volcanoes Influence Climate, 2018). As said before, volcanic eruptions generate 110 million tons of carbon dioxide every year. Humans release 10,000 times more carbon dioxide than volcanoes (How do volcanoes affect world climate?, 2005). Man-made anthropogenic processes are more significant to climate change. Climate drivers such as volcanic eruptions and heat trapping in the atmosphere are natural causes we cannot curtail. Human causes, such as vehicles, factories, and many other things human-operated, burn fossil fuels that travel into the stratosphere. In addition, humans are the ones to cut down the plants that absorb the carbon dioxide. Scientists are able to tell that humans play a large role in global warming because they are able to distinguish carbon dioxide derived from fossil fuels and carbon dioxide derived from natural resources by the concentration of atoms (How Do We Know That Humans Are the Major Cause of Global Warming?, 2017). Over the past hundreds of years, scientists noticed an increase in carbon dioxide level derived from fossil fuels and an increase in global temperature from year to year (How Do We Know That Humans Are the Major Cause of Global Warming?, 2017). There are almost 8 billion people in the world that burn fossil fuels everyday, making humans the main cause of global warming and climate change on planet earth.

The Development of Civilization Essay - 2264 Words

The Development of Civilization Our civilizations are merely a wrinkle in time. Billions of years ago, during the Paleolithic Culture people had only knowledge for basic survival. The Stone Age was a time for hunting and gathering, building tools, and making fire. As the human race evolved, so did the culture. This is when the Neolithic Culture was born. People started taking control. Farms sprang up and sedentary villages began to take form. Amazingly, not too far from these progressing cultures grew civilizations. When one wants to look at the true heart of a civilization, they must first understand the civilization’s beliefs, moral standards, social interaction, attitudes, values and social consciousness. Without a sincere†¦show more content†¦The Athenians were superbly educated in the arts and sciences, and trained to be extremely productive in times of war and peace. When looking at their educational and philosophical output it is simple to see that the Athenian people valued their futures. Without educational programs for the Athenian youths, Athena would have lost their civilization long before it initially peaked. Undoubtedly, Athenian people had a productive social consciousness, and realized that education and knowledge was quite important. They knew that the future of their city-state depended on the â€Å"smarts† of the people in it. Social awareness was not usually number one to people back then. Normally, city-states were concerned with war and gaining land. While the gross majority of Greece were fighting and stealing, Athenians were busily figuring out the philosophy of life. Clearly, the Athenians were socially aware of what was going on in their lives, through education and philosophy. The Spartans on the other hand were more concerned with being brute and strong against their enemies. A typical Spartan soldier would have to endure unbelievable pain and hardship to become a respected Spartan and citizen. Their moral standards must have influenced them to exploit their respect toward physical pain and suffering. Many historians believe Spartans were cunning, lying cheaters.

Black Swan, Cinema Paper Free Essays

Sarah Risner Dr. Foley Cinema 19 November 2012 Black Swan â€Å"Black Swan† is a movie with a dark transformation of Nina the white swan metamorphosing herself into the black swan, with symbolism and psychosis playing well within the movie. Most of this movie plays into the world the ballerina, and exposes some of the hidden motives of this world. We will write a custom essay sample on Black Swan, Cinema Paper or any similar topic only for you Order Now The other world this movie plays into is the world of someone with psychosis, and the mysteries that follow between both worlds. It seems the ballerina world feeds into the patient with psychosis and feeds the mental illness. After one watches this movie they will be horrified and troubled at the same time. The character of Nina will leave one trying to figure out the mysteries of Nina’s life. It actually leaves the audience with more questions than answers after watching the movie. The questions are what give the movie great success. The setting of â€Å"Black Swan† takes place in New York at a ballerina studio where Nina and Lily are preparing for the production of Swan Lake. The plot of the movie is about Nina and her obsession with dance. Her mother is a former ballerina and is very controlling of her daughter. The dance director by the name of Thomas Leroy decides to replace the character Beth with Nina for the new season of Swan Lake. Nina is his choice, but he also has eyes for the character Lily. Nina feels competition between herself and Lily. Nina has an obsessive view between herself and Lily. This part is complicated because it means the character has to play both the white swan and the black swan. The white swan requires the ballerina to play a part of purity and elegance. The black swan part requires the ballerina to play a part of cunning and sexuality. Nina will go to the dark side of this character and it will drive her insane. Lily and Nina form a candid friendship which seems to be insane itself. The conflict of this movie is the inner struggle of Nina with her own personality waging war against itself. The character change of this movie is with the main character of Nina. Nina starts out innocent and ends up exploring her dark side in order to turn herself into the character of the black swan. Some universal symbolism found in this movie is the use of the character Lily as Nina’s doppelganger. The symbol is of course is the twin/double identity of Nina’s self. This embodies Nina’s good/evil sides of herself. Mirrors are used in the film to show Nina splitting into two different personalities. The cultural symbolism in this movie is seen in black and white symbolism. Black of course shows the dark side of Nina, and white the good side of Nina. It is shown with actual color within most of the movie though. The theme of this movie is the cost of fame, along with the dark sides of show business. It also shows complexities of trying to be perfect and how the stress of perfection can be one’s downfall. According to The Sticky Shoe Review by Logan Arney, says the Black Swan having a target audience is a bold statement. The reason for this being that the movie has attracted all kinds of people to watching it due to the Oscars and so forth. It has almost created its own target, or curious on-seekers just wondering what goes on in this film. The marketing of this film has many causes to it such as big names. The big acting names are Natalie Portman who stars in this film, director Darren Aronofsky. Aronofsky himself has directed big hits such as â€Å"The Wrestler†, â€Å"The Fountain†, â€Å"Requiem for a Dream†, and â€Å"Pi†. Natalie Portman has starred in big hits such as â€Å"V is for Vendetta†, and â€Å"The Other Boleyn Girl†. Adding to this list are the other two big actors being Vincent Cassel, and Wynonna Ryder and not to mention this film being the buzz at the Venice Film Festival of 2010. There is a lot of PR when this bag of names is mentioned (Mu). The script used in this film was written by Mark Heyman, Andres Heinz, and John McLaughlin. The story was written by Andres Heinz (IMDb). According to Tom Long, giving his critical response about this film, he believes the movie works due to Portman’s great commitment to character which gives the movie its greatness. He also admits this movie is not necessarily for everyone, but for anyone looking for the horror and craziness in a ballerina movie (Long). The mise-en-scene in â€Å"Black Swan† shows up as black and white color. For one, the costume of the dancers shows as black and white. The dress in the reception is black, as are the walls of the ballet company. The editing of this movie was done by Andrew Weisblum (IMDb). What made the editing so great in this movie was how the emotions were transferred on film while adeptly telling the good story. The lighting in â€Å"Black Swan† is very dramatic with tones of greens and magentas showing up within different characters, and of course the black and whites within the film. The music in this film is like any suspense thriller movie in that one knows something is about to happen when a scary tune starts to play. The sound effects seem to mimic the actual swan cry in some parts of the movie. This in effect makes the film very symbolic of the actual animal of a swan. This movie has many camera angles that clearly explore this movies symbolism. One of the high-angle shots of this film is when the character of Nina when she is dancing on stage, and she is looked down on by the audience. A good close-up shot are when it shows Nina’s feet and it shows how much control she has in her movement. A significant wide-shot in the movie is when we are in Nina’s bedroom, and there is light hitting the bed. The medium-shot in the movie that probably catches most everyone’s eye is when Nina is passing her other self on the subway. This movie uses mostly the fixed-camera. In conclusion, this movie clearly goes beyond any limit set forth on most film. It has used more symbolism than other movies which makes it quite interesting. It also has the uncanny terroristic theme of terror imposed within it. One feels as if the ballerina world has been exposed while showing to what extremes the female ballerina will go thru to stay skinny, and be perfect. The black and whites of the film show to what extremes in which the ballerina will show herself through. Works Cited Arney, Logan. â€Å"Black Swan. The Stickey Shoe Review (2010): 1.

Not for Arguments Sake free essay sample

Arguing for me is like music for a musician, or soccer for a soccer player; I love to do it. I could argue against something I agree with, or against something I have no opinion about. I don’t do it for the sake of arguing, but instead for the sole purpose of understanding every side to a story—putting one’s-self in somebody else’s shoes. In essence, I love to argue, because I want to understand the big picture, all the different angles. Understanding, in my opinion, is the best reward of education. In math one might be learning algebra, geometry, or calculus, but it’s only learned when one understands why a=b and that there is more than one way to get the same answer, to achieve the same goal. In history, one learns about the Constitution and also understands why the president (of the U.S.) is elected through an electoral college, making the United States a democratic republic. In English one learns about different styles of literature, developing his/her own style and understanding the value of the choices one makes in his/her writing. Inside of school, all of those subjects are isolated, each having its on set of rules and meaning, but outside of school, in society, all of those different subjects, and their teachings come together. One could take what he/she learned in math—about the different ways of achieving an answer—and what he/she learned in history—about the reason for the type of government in the United States—and what was learned English—about having a distinct style and the value of choices—to conclude that each society makes its own choices in the way its governed, which can be different from one’s own society, with the same common goal in mind, well-being of its citizens. One could also conclude that in an argument, there is no right opinion or wrong opinion, there are only reasons why somebody feels the way they do about a topic, which only takes a little under standing. Every conflict is an argument. The more violence present in an argument means less amount of understanding by each side. We have brains to learn, to think, to make choices, and to communicate, to argue, without the use of violence. We have the ability to receive education, and we have languages to understand each other in. I argue in English, Spanish, French, and Portuguese.
