...GREEN HOUSE EFFECT INTRODUCTION In temperate countries some economically important plants that cannot grow outside at a very low temperature during the winter are grown in glass-walled & glass-roofed growth chambers (known as glass houses)exposed to sunlight. Glass houses are also used in sub tropiacal regions during winter months & relatively cold high altitude for high value horticultural annual crops including flowers on a cmmercial scale as well as for research work especially for breeding of new varities & crop physiological & pathological studies. Temperature within the glass house rises because of the glass of the roof & walls through it allows entry of sunlight with little obstruction,resist the escaping of the reflected light of longer wave-lengths rich in infra-red rays resulting in a heat built up. Such glass houses are called green housesas the light & heat within such houses prove very effective for profuse growth of green plants. The property of trapping heat by carbon di oxide & other gases of the atmosphere is similar to the glass cover of green house that reasists the escaping of heat radiated from inside of the house.As such, these atmospheric gases are called green house gases that resist the escaping of radiated heat from the earth by absorbing infra red rays & particularly reflecting the trapped heat back to earth's surface.this phenomenon is therefore called the green-house effect in wicch certain atmospheric gases act in a manner similar to the glass...

...Green House Effect The green house effect is the warming up of the atmosphere. This happens due to the fact that there are certain gasses in the atmosphere that allows a certain wavelength of electromagnetic waves to freely pass through, while for the other types of electromagnetic waves, it doesn’t allow free movement. For example, high-energy electromagnetic waves like ultraviolet and gamma radiation get absorbed by the atmosphere. This allows for other radiation with a lower frequency to pass through the atmosphere and heat the Earth. Greenhouse Gases Carbon dioxide () is one of the greenhouse gases. It consists of one carbon atom with an oxygen atom bonded to each side. When its atoms are bonded tightly together, the carbon dioxide molecule can absorb infrared radiation, which happen to be vibrating in the same frequency as the molecule, causing the molecule to vibrate. The phenomena where both the molecule and the infrared radiation vibrate in the same frequency and combine, it’s called resonance. Fortunately, the range of frequency of Infrared radiation is in the region of the frequency of the molecules. Eventually, the vibrating molecule will emit the radiation again, and it will likely be absorbed by yet another greenhouse gas molecule. This absorption-emission-absorption cycle serves to keep the heat near the surface, effectively insulating the surface from the cold of space. Carbon dioxide, water vapor (), methane (), nitrous oxide (), and a few other gases...

...The Greenhouse Effect Issue Statement While some people believe the earth's climatic changes are due to the fact that the universe is getting older, others believe it is due to the greenhouse effect. The greenhouse effect is a naturally occuring phenomenon that is responsible for trapping heat near the earth's surface and keeping the planet warm. It is called the greenhouse effect because the way it works is similar to the way in which a green house functions. In a greenhouse sunlight passes through the transparent roof and walls and strikes the objects inside- plants, flowerpots, tables, and so forth. These objects absorb energy from sun, become warmer, and then give off energy themselves in the form of heat. Only a little of this heat energy passes out through the glass, much of it is "trapped" in the greenhouse, raising the temperature inside. In some ways, the earth functions rather like a greenhouse except on a much larger scale. Although the greenhouse effect has only recently been in the news, is nothing new in th history of our planet, has played major role in making life on earth possible. Without the greenhouse effect, the earth would be too cold for living thing to survive. The big question today is "If greenhouse effect is natural, why are people so worried about it. Is soemthing good turning bad?" Up until about 150 years ago the compostion of the earths atmosphere had remianed relatively unchanged for several thousand years. Since mid 1800s certain...

...9/25/12 THE GREENHOUSE EFFECT THE GREENHOUSE EFFECT What is the Greenhouse Effect? Life on earth is possible because the sun provides energy and warmth. The sun's rays pass through the atmosphere and are absorbed by the earth's surface, which heats up and radiates energy back into space. Some of the gases in the atmosphere capture and hold radiated energy, keeping the surface of the earth warm, much as the glass of a greenhouse keeps the plants inside warm. Without these greenhouse gases such as carbon dioxide (CO2), all radiated heat would be lost into space and the surface of the earth would be cold and barren. This natural phenomenon acts like a blanket around the earth, is essential for life, and is often referred to as the greenhouse effect. Man-made emissions are leading to increased amounts of greenhouse gases in the atmosphere. The increases in greenhouse gases are trapping more of the energy radiated from earth and are likely to lead to global warming and weather extremes. The possible impact of human activity on the greenhouse effect was first recognized in the early 1800s. By the turn of this century, calculations were being made relating increases in atmospheric carbon dioxide to temperature change. In the early 1900s it was estimated that doubling or tripling the amount of carbon dioxide in the atmosphere would lead to a temperature increase of up to nine degrees Celsius. Since then, carbon dioxide levels have increased by 26 per cent, and global temperatures...

Global warming has become a major problem as we move on to 21st century and beyond. Like the old say goes, prevention is better than cure. We have done enough damage, knowingly and unknowingly we have contributed to global warming. Our efforts and determined contribution to reduce global warming and spare the ecosystem to recover thereby cautiously working restore the balance of nature is very urgent. Pollution of the atmosphere has to be checked and anything related to the release of the greenhouse gases should be monitored. Deforestation should be stopped as it causes the concentration of carbon at a greater extent. It has been said that it takes roughly 19 trees to make one ton of paper and that the usage of one ton of recycled paper will save approximately 17 trees. The burning of wood should be reduced to a greater extent as it releases oxidizable carbon to the atmosphere whose presence in greater amount causes the elevation of temperature. LPG stoves can replace the fire wood burning. Bio...

...certain character. The most important color in this book is green, more specifically the green light, shows Gatsby’s hope and ambition to achieve his American dream in the beginning to how he eventually fail to attain it with money. The color green reminds us of hope and renew. In the book, Gatsby himself views the green light as a sign of he should go for his dream. He always believes Daisy will leave Tom and choose to marry him again. In real life, when the traffic light turns green, it is a sign tells us it is safe to go. Gatsby interprets this as he is right with everything he is doing right now and he will soon achieve his goals. When he says “I’m going to fix everything just the way it was before,” he said, nodding determinedly. “She’ll see.”(Fitzgerald, 110.), it shows he has the confidence that he is on the right track. However, the narrator Nick...

...they must take into account which colors to use; typically the colors have meaning to it. An artist's palette during the 1920s was most likely filled with glitter and glam and lots of color. Like an artist, F. Scott Fitzgerald intertwines these colors into his novel The Great Gatsby not only to establish flow, but to emphasize the importance of the character’s desires, wealth, and avarice. Because Fitzgerald weaves colors into the setting, characters, and plot, the reader is able to comprehend why certain characters act the way they do and why some put up masks. Confidence and hope is found within the color green, a color in which correlates with the green light that is seen towards the end of chapter one. Fitzgerald’s paintbrush serves...

...plaids in coral and apple-green and lavender and faint orange, with monograms of Indian blue,” (Fitzgerald 92). The theme of colors is present throughout the entire novel The Great Gatsby. Although some colors are more prominent than others, all are equally important in displaying qualities of each character. Each color represents a distinct feeling for the duration of the book. Some are very obvious in what feeling they are trying to express, while others are more abstract, but significant nonetheless. Colors are the best way to exhibit an overall feel for a character or time frame. As a rule of thumb, white usually...

...life. Others also believe that freedom, relationships, and fulfillment play a role in the American dream. Critics often suggest that not everyone has the same opportunities of being able to “live the dream” because of class, race, religion, and ethnicity. In the story, The Great Gatsby, Fitzgerald symbolizes the hope and opportunity that can be found in the new land, what comes to be known as the American Dream in the quote, “a fresh, green breast of the new world(Chapter 9).” The color green symbolizes the hope and opportunity that can be found in the new land, what comes to be known as the American Dream. An example of a metaphor in the story is Gatsby’s house. This image serves as a key symbol of aspiration, reflecting on both Gatsby's success as an American self-made man and the mirage of an identity he has created to win Daisy's love. Gatsby follows his American Dream as he buys the house to be across the bay from Daisy, and has parties to gain wide-spread recognition in order to impress her. Yet, Owl Eyes compares Gatsby's mansion to a house of cards, muttering "that if one brick was removed the whole library was liable to collapse(Chapter 3)." Ultimately, the inevitable collapse occurs, as Gatsby loses Daisy and dies absolutely friendless, prompting Nick to refer to Gatsby's mansion...

...One Will Ever Know that is made by Izel Vargas. 1. Firstly, I would like to discuss the use of color in this picture. Wearing a dark green T-shirt, with two broken and bloody arms, holding a dark black gun, a policeman whose head is an arguing man and woman is in the picture. The hues of this artwork are red, green, orange and yellow, and each hue has a value. The artist uses a dark value of pure red, green and yellow, a light value of pure orange. Similarly, the tint of this picture is light orange, and shades of this picture are dark red, green and yellow. For example, the skin of the arms are light orange; the bloody arms are dark red; the T-shirt is dark green; the logos of the shirt are dark yellow. The artist also uses the neutral colors which are white, black, dark black and dull brown. For example, the gun and leather belt are dark black; the background of the arguing man and woman is white; the background of the whole picture is black. The artist used the color temperature. The dark red of the bloody arms and dark green of T-shirt are warm, because the background is black that is the cooler color. 2. Secondly, I want to describe the use of line in this picture. The processes used in this particular work are contour line, hatching and cross-hatching. The artist uses the contour line to draw the outer edge of the man, woman and house in the artwork. For example, the lines in the hair of the man and woman vary in thickness and regularity. The lines of the woman’s face...

...The Great Gatsby, F Scott Fitzgerald Chapter 6 Color Analysis May 24, 2011 Jay Gatsby | -“torn green jersey” (104): The color green symbolizes wealth and money. At this time in the book, Gatsby is working for Dan Cody, the guy who greatly supplies his wealth. The fact that the jersey is torn signifies the hard work that Gatsby demonstrates which then leads to him reaping the benefits of hard work. This section furthers to talk about his parents and how they were “unsuccessful farm people” also that Gatsby “was a son of God.” This is to say that although Gatsby’s parents were hard workers, they were unsuccessful in reaching their ideal “American dream”. Gatsby is currently making those dreams happen. He was helping to complete his father’s business, and is therefore relatively “a son of God.”---- The green jersey also symbolizes the new life that he yearns for that is full of wealth. Right at this stage in the book, Gatsby is called different names: Gatsby, James Gats, Jay Gatsby, young Gats: Each name recognizes a different stages of growth towards the Wealthy life.-“His brown, hardened body lived naturally through the half fierce, half lazy work of the bracing days.” (104): Brown is the color of earth, and of “getting down and dirty”. It further symbolizes the humility Gatsby underwent while with Dan Cody. Because the idea of wealth plagued Gatsby (“his heart was in a constant turbulent riot.”), he reaped the fruit of his labor as discussed with the color change discussed...

...size I mean the visual size of the four outstanding images in the painting. The force of attraction with which the images are featured in the painting seem to draw my feet and eyes closer for a more critical view and my hands for a reach to feel its surface. The size of the frame is pretty large and towering if one faces it. Images in the painting include a beautiful, young lightly made up lady gracefully leaning by a majestic, strong looking, white saddled stallion as if for support. These two figures were standing under a four branched rich green leafy oak tree. A little farther behind them were a high twin- like rocky mountains. I admired the natural and wholesome appearance the painting exudes. The lofty mountains which form the main background of the painting stand imposing over a flowing stream by its foot, and a green valley. They seem to call a viewer’s attention from a distance father away from the woman, horse, maize field, house and tree. I was mostly attracted to the figure of the woman. Her figure to me is an embodiment of gracefulness and tenderness. She radiates strength and confidence. As a woman I took away from the picture a feeling of completeness. The entire landscape of the entire painting looks lively and healthy. Although Edmund uses more of dark colors for the vegetation, his mixture of red, yellow, and a shade of orange on the woman’s gown and face, and the patchy flower bushes at the stump of the tree, and his use of purple on the mountains and tree...

...The green light has a many different symbolic meaning that what first comes to thought. Gatsby would often reach towards or look at the light. Also, Gatsby built his house across from Daisy and used the light to feel closer to Daisy. When the green light is first introduced to the book, it seems very miniscule in the grand scheme of things, but when further looked into, the role of the light is revealed as a important symbol to the story. The most obvious symbol of the green light is Gatsby’s desire and hope to be with Daisy once more. In chapter one Gatsby is at his dock looking longingly towards Daisy’s dock with the green light. Then later on in chapter five Gatsby is caught reaching towards the green light as if he expects Daisy’s hand to be next to his. Gatsby has a sense of hope when looking at the light. That hope is carried on throughout the book. He believes that it is his way of staying connected to Daisy and hope to be reunited once again with her. He hopes that Daisy will learn to love him like she once did, and things would go back to like they were before. Daisy, of course, can’t bring herself to leave Tom for Gatsby. Gatsby continues in his hopeful fantasy of the past. He becomes overly consumed by his fantasies that his thought process in the present is manipulated into thinking that are just simply not reality. Its a dream that Gatsby strives for, and will go to any lengths to get it. When Gatsby realizes at the hotel that Daisy also shares love for Tom...
