Geothermal Energy Essay - 4754 Words

Geothermal Energy The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons. Hydroelectric power tends to upset the ecosystems in rivers and lakes. It affects the fish and wild life population. Nuclear energy is a very controversial subject. Although it produces high quantities of power with relative efficiency, it is very hard to dispose of the waste. While wind and solar power have no waste products, they require enormous amounts of land†¦show more content†¦The continental crust consists of igneous and sedimentary rocks. The oceanic crust consists of the same with a substantial layer of sediments above the rock. The crust covers the outer ridged layer of the earth called the lithosphere. The lithosphere is divided into seven main continental plates. These continental plates are constantly moving on a viscous base. The viscosity of this base is a function of the temperature. The study of shifting continental plates is called Plate Tectonics. Plate Tectonics allows scientists to locate regions of geothermal heat emission. Shifting continental plates cause weak spots or gaps between plates where geothermal heat is more likely to seep through the crust. These gaps are called Subduction Zones. Heat emission from subduction zones can take many forms, such as volcanoes, geysers and hot springs. When lateral plate movement induced gaps occur between plates, collisions occur between other plates. This results in partial plate destruction. This causes mass amounts of heat to be produced due to frictional forces and the rise of magma from the mantle through propagating lithosphere fractures and thermal plumes sometimes resulting in volcanism. During plate movement, continental plates are constantly being consumed and produced changing plat e boundaries. When collisions between plates occur, the crust is pushed up sometimes forming ranges of mountains. This is the way that mostShow MoreRelatedGeothermal Energy Essay1270 Words   |  6 Pages Geothermal Energy In todays world, we are stuck in a constant debate about efficient energy usage and production.

Symbolism in Hawthornes Young Goodman Brown Essay

Symbolism in Young Goodman Brown Edmund Fuller and B. Jo Kinnick in â€Å"Stories Derived from New England Living† state: â€Å"Hawthorne’s unique gift was for the creation of strongly symbolic stories which touch the deepest roots of man’s moral nature† (31). It is the purpose of this essay to explore the main symbolism contained within Nathaniel Hawthorne’s tale, â€Å"Young Goodman Brown.† Stanley T. Williams in â€Å"Hawthorne’s Puritan Mind† states that the author was forever â€Å"perfecting his delicate craft of the symbol, of allegory, of the few themes and oft repeated character-types which were to haunt forever the minds of those who know New England† (42). Let us begin with the opening lines of the story: â€Å"YOUNG†¦show more content†¦To have so much symbolism in the very opening sentence of the tale is almost too much for the human mind. Examining the second sentence of the short story, we see: â€Å"And Faith, as the wife was aptly named, thrust her own pretty head into the street, letting the wind play with the pink ribbons of her cap, while she called to Goodman Brown.† What do the pink ribbons signify? 1. â€Å"The ribbons are in fact an explicit link between two conceptions of Faith, connecting sweet little Faith of the village with the woman who stands at the Devil’s baptismal font. We can legitimately disagree about the meaning of this duality; the fact remains that in proposing that Faith’s significance is the opposite of what he had led the reader to expect, Hawthorne violates the fixed conceptual meaning associated with his character. . . .They are part of her adornment of dress, and they suggest, rather than symbolize something light and playful, consistent with her anxious simplicity at the beginning and the joyful, almost childish eagerness with which she greets Brown at the endâ⠂¬  (Levy 124). 2. â€Å"These ribbons. . . are an important factor in the plot, and as an emblem of heavenly faith their color gradually deepens into the liquid flame or blood of the baptism into sin† (Fogle 24). 3. â€Å"The pink ribbons that adorn the cap which Faith wears . . . are a badge of feminine innocence† (Abel 130). 4. â€Å"Neither scarlet nor white, but of a hue somewhere between, the ribbonsShow MoreRelated The Symbolism of Hawthornes Young Goodman Brown Essay2725 Words   |  11 PagesThe Symbolism of â€Å"Young Goodman Brown†Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚        Ã‚   Nathaniel Hawthorne’s short story, â€Å"Young Goodman Brown,† shows the reader the author’s power as a symbolist.    Frederick C.

One Note at a Time free essay sample

Black and white. Everything is black and white when it comes to learning a piano piece. Simple little black dots weaved into the 10 black lines, 5 for treble and 5 for base; all arranged on a white sheet of processed paper. The keys, both black and white and glossy glide under my fingertips. I reach for the lamp’s knob and twist it. Click, click, click and the white light is illuminated. Gleaming, the bulb reflects off of each ivory key and a glare can be seen off of the raised ebony cover. Searching through the pile of sheet music stacked on the black Grand Piano I notice, placed directly to the right of the music stand, that special piece I’ve been anticipating. A challenge, most definitely, but a beauty in itself; the composition will be entertaining for me to play and for an audience to listen to. I place it into the caressing music stand. We will write a custom essay sample on One Note at a Time or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It cradles the arrangement for me and keeps the exposition safe amidst the upcoming journey. My hands fondle the music. Analyzing each detail of chords, pedal movement, and the count of each note, I single out the melodies by placing my pointer finger at its location on the music. Then, one hand at a time, I locate their partners on the keys for both clefs. Measure by measure, four beats at a time, I focus on the first note in the first line. Is it a half note, quarter note, or whole? As I take into account the meter time, which would resemble a base or drum beat in any modern song. Take Cyndi Lauper’s well known song for example, Girls Just Wanna Have Fun: one, two, three, four, one, two, three, four. Four beats in each measure decides a half note held for two beats, quarter notes for one beat, and a whole note obviously counted for four beats. I’ve determined the meter time and counted out the notes. But what note is it? An A, B, or possibly a G? There are seven different notes; A-G in the alphabet, however, where those notes stand on the staff, the five hor izontal lines where music is written, is difficult to remember. A simple trick I have learned that greatly advanced my note reading abilities are the acronyms. For the treble clef the lined notes proceed as following from bottom to top: Every Good Boy Deserves Fudge. As for the spaces, they spell out F.A.C.E. The base clef is even trickier, with an acronym for the spaces saying All Cows Eat Grass, and for the Lines, Great Big Donuts For Alvin. Memorization and time has helped with the agility of this technique. Learning song after song makes it easier to read the notes than the time before. After I have read each note carefully and acknowledged where they lie on the keys, I then challenge the brutal chords. These beastly stacks of notes are initially confusing to finger on the keys but after much practice, my fingers comfortably fall into place. Slowly starting from the beginning of the first line, I play the tune until the end of that line. I return back to the beginning of the pie ce and run through to the end of the line once, twice, three times more. Choppy and disassembled sounding at first but by the third or fourth trial, my performance has become somewhat fluid and naturally melodious. I have quickened the metronome on the first line, however, I must continue to the following lines. I repeat my steps of reading the notes and fingering the chords almost mechanically. Progressively moving down the sheet music and onto the next page, I study the music. At an expressly demanding interval, I halt and examine the melody. A mixture of sixteenth notes and rests, slurs, sharps and flats engulf the staff. I practice these sections 5 to 7 times instead of 3 to 5. Little by little my fingers memorize where and how far they must move to get from one key to the next; from one chord to an arpeggio (the notes of a chord broken up and played as a succession). Before long I must advance: to the end. The entire piece welcomes my familiarity with it once the weight of my hand presses down onto the last chord or note. Yet, the piece lacks rhythmicity and emotion. A rehearsal of the entire piece is practiced day and night until perfected. Over and over again it is engaged in recreation if a section requires precision in accents or dynamics. What is the product? A final recital expresses my personality and emotion telling a story dependant upon interpretation. Each period sets a mood of excitement, tranquility, or possibly passion with indescribable blends of notes and all that is known is the generation of pleasing endorphins. Yet, it is still black and white; plain and simple. The melody is fact, and the euphonious chords are unchanging. Harmony so constant and firm would never emerge without any one of the small portions which compose this magnificent expression.
