benefits of a volcano essays Volcanoes both harass and help mankind. As dramatically demonstrated by the Mount St. Helens on May 1980 Volcanic materials ultimately bread down to form some of the most fertile soils on Earth, cultivation of which fostered and sustained civilizations. People use volcanic substances as construction materials, as abrasive and cleaning agents, and as raw materials for many chemical and industrial uses. The internal heat associated with some young volcanic systems has been harnessed to produce geothermal energy. The Earth's crust, on which we live and depend on, is in large part the product of millions of once-active volcanoes and tremendous volumes of magma that did not erupt but instead cooled below the surface. For example, volcanic ash blown over thousands of square kilometres of land increases soil fertility for forests and agriculture by adding nutrients and acting as a mulch. Groundwater heated by large, still-hot magma bodies can be tapped for geothermal energy. And over many thousands of years, heated groundwater has concentrated valuable materials including copper, tin, gold, and silver, into deposits that are mined throughout the world. Therefore the benefits of living near the volcano outweigh the costs. Given enough rainfall, areas buried by new lava recover quickly; revegetation can begin less than one year after the eruption. Erosion and breakdown of the volcanic material can form fertile soils over periods of tens to thousands of years. These rich soils fostered the agricultural development of the Hawaiian Islands, as represented principally by the sugar, pineapple, coffee, and macadamia nut industries. This is also the case of Mt Merapi in Indonesia where farmers are excited and continues to plant new rice on the rich soil. When snakes slither from their pits and move down the mountain thats a sign for villagers to toss rice and tonics of herbs and spices into the crater . Mt merapi is one of indon...

Major Themes in Much Ado About Nothing

Major Themes in Much Ado About Nothing Shakespeare’s treatment of love in ​Much Ado About Nothing​ differs from his other romantic comedies. Sure, it shares the same​ stagy plot, which finishes with the lovers finally getting together, but Shakespeare also mocks the conventions of courtly love that were popular at the time. Although Claudio and Hero’s marriage is central to the plot, their love at first sight–type of relationship is the least interesting one in the play. Instead, the audiences attention is drawn to Benedick and Beatrice’s unromantic backbiting. This relationship seems more believable and enduring because they are painted as a match of intellectual equals and dont fall in love with each other based on superficiality. By contrasting these two different types of love, Shakespeare manages to poke fun at the conventions of courtly, romantic love. Claudio uses highly contrived language when speaking of love, which is undermined by Benedick and Beatrice’s banter: â€Å"Can the world buy such a jewel?† says Claudio of Hero. â€Å"My dear Lady Disdain! Are you yet living?† says Benedick of Beatrice. As an audience, we are supposed to share Benedick’s frustration with Claudio’s transparent, pompous rhetoric of love: â€Å"He was wont to speak plain and to the purpose, like an honest man and a soldier...His words are a very fantastical banquet, just so many strange dishes.† DeceptionFor Bad and Good As the title suggests, there is a lot of fuss over very little in the play- after all, if Claudio weren’t so impetuous, Don John’s rather weak plan to ruin Don Pedros reputation and disrupt the marriage of Claudio and Hero wouldn’t have worked at all. What makes the plot so intricate is the use of deception throughout, via trickery, lies, written messages, eavesdropping, and spying. Back when the play was staged, the audience would have understood that title is also a pun on noting, or being observant, even bringing the deception theme into the title. (The words are thought to have been pronounced similarly back then.) The most obvious example of deception is when Don John falsely slanders Hero for his own mischief, which is countered by the friar’s plan to pretend Hero is dead. The manipulation of Hero from both sides renders her a passive character throughout the play. She does very little and becomes an interesting character only through the other character’s deceit.   Perception of Reality Deception is also used as a force for good in the play, as in Beatrice and Benedick’s scenes where they overhear conversations. Here, the device is used to great comic effect and to manipulate the two lovers into accepting each other. The use of deception in their storyline is necessary because it is the only way they could be convinced to allow love into their lives. Phrased another way, the theme could also be called one of perception, or how truth can differ from reality. Both couples have to discover the true nature of their beloved. It is interesting that all of Much Ado’s characters are so willing to be deceived: Claudio doesn’t stop to suspect Don John’s actions, both Benedick and Beatrice are willing to completely change their worldview after overhearing things about each other, and Claudio is willing to marry a complete stranger to appease Leonato. But, then again, it is a lighthearted Shakespearean comedy.
