The arctic tundra is the worlds youngest biome. it contains the last set of continental glaciers from about 10,000 years ago. As the glacier went away it scraped away the soil from underneath, leaving bare rock. Before plants were able to grow the arctic tundra had to develop soil. Soil forms very slowly on the tundra because the cold weather slows the rate at which chemical reactions occur. Only a thi layer of soil has formed in the thousands of years since the glaciers retreated. The Southern part of this tundra is mostly made up of bare rock.
There is little plant life in the tundra biome because the soil there isn't nutritious for certain plants to grow. The soil there is very much like sand, and the plant there have made many adaptations to survive in the tundra. Many of the plants have formed fuzzy hairs to keep warm, and some have developed a low root system or grow close to the ground to prevent permafrost and to keep out of the winds path. The plants of the arctic tundra have developed special characteristics so they can live in the tundra.
Many animals inhabit the tundra. Each animal has adapted in their own special way. The Arctic Fox and Polar Bear both have thick coats to keep them warm in the freezing climate. The Caribou better known as the Reindeer have long antlers, and very large hooves to help climb up steep mountains or rocks. Every animal in the tundra has something to help them with the chilly climate.
The arctic tundra is found in Alaska, northern Canada, edges of Greenland, northern Scandinavia, northern Russia, and Siberia. It is the youngest, coldest, and least populated biome in the world. The floor of the tundra is permanently frozen from four inches all the way up to three feet. In winter it can get down to -95 degrees and in summer it only hits 50 degrees. The tundra gets six to ten inches of snow each year. Wind speeds in the tundra…...

Drilling Away from the Obvious

...Drilling Away From the Obvious In an Energy Crisis 5/1/2011 Author | Drilling Away From the Obvious, In an Energy Crisis. Junior High and High school students are woken up and drilled to be at school on time. Then college students are drilled by our professors for excellence in our works. Upon entering lower management, these personnel are drilled by middle management and these in turn are drilled by upper management; all through the business food chain, up to senators who are drilled by their constituents for solutions to problems. Education of the economy of our Nation’s oil industries’ definitions of oil, oil consumption, recoverable oil, oil rigs & their companies will raise awareness to the meager effects of drilling for domestic oil and raise awareness to the true potential of alternative energies. Comprehension of our oil industries’ limited footprint of jobs and trickledown effects as compared to green jobs’ large footprint of trickledown effects and job capacity. Our Nation’s interests are found in weaning our dependence of foreign oil to green alternatives. America contains many sites of oil, numbering well into the trillions of barrels of oil; however we lack one or two things to recover each of these sites’ deposits, these two conditions are technically recoverable and economically recoverable (Wikipedia, World Oil). A technically recoverable reserve is defined as a deposit that can be recovered with available industry equipment (Wikipedia, World......

Home Away from Home

...Home Away From Home After living in a small in Ghana, I found a new home in New York City. Although both cities are millions of miles apart, they interestingly share some amazing similarities as well as differences. For instance, many believe that “The Big Apple” (New York City), is where everything happens. They say “if you can make it in New York, you can make it anywhere”. However, the big apple is not the only place where big things happen. Akib also known as “Dam City” has the biggest hydro-electric dam which generates and supplies electricity throughout the country and even to some of its neighboring countries. So the natives like to say “Akib Nkania” which means “Akib lights”. However, besides their similarities, these cities have their extreme differences as well. Compared to the Big Apple where everyone lives in the fast lane and the city mostly filled with people, cars and skyscrapers, Akib is filled mostly with valleys, trees, rivers and cannon and very few people. The weather is characterized by either a hot summer or a cold winter in New York whereas, Akib has moderate tropical temperatures with heavy rains between May and June and a dry season between October and February. I call both cities my home because together they keep me in balance. These places represent the best of both worlds. New York is more hurried and rushed when I need the rush, and Akib gives me a slower pace when I need to relax....

Biomes

...Biomes Tropical rainforest: * What: Hot and wet areas with broadleaved evergreen forest * Where: Within 5°N and S of the equator * Climate, limiting factors: High rainfall(2000-5000 mm yr-1), high temperatures( 26-28°) and high insolation, P>E rain washes nutrients out of the soil, so nutrients may limit plant growth * Structure: amazingly high levels of biodiversity: plants compete for light thus growing tall to absorb it, so there is a multi-storey profile to the forests called stratification. Many niches and habitat for animals and large mammals can get enough food * Net productivity: produce 40% of NPP of terrestrial ecosystems. Fast rates of decomposition, respiration and photosynthesis. Biomass gain very high, rapid recycling of nutrients * Human activity: more than 50% of world’s human population live in the tropics/subtropics forests exploited e.g. nutrients quickly exhausted by agriculture, commercial logging of timber * Issues: logging, conversion to grazing and to plantations forests exploited for economic development * Examples: Amazon rainforest, Borneo rainforest Desert: * What: dry areas usually hot in the day and cold at night as skies are clear and there is little vegetation to insulate the ground.

The Ones That Walk Away from Omelas

...Omelas The short story “The ones who walk away from Omelas” has many symbols in it. A lot of these symbols play a major role in contributing to theme of the story. The symbols are the summer solstice, Colors in the solstice, the birds (Swallows), the flute player, understanding, and of course the child in the cellar. These symbols make the story come together. Without these symbols the story would be incomplete, it would not make sense. When the reader actually takes the time to think about the symbolization in the story, it all comes together. All of the symbols that bring the story together shows that things are not always as perfect as they seem. In this story the author describes the perfect town, the perfect citizens, basically a utopian society. Underneath it all there is evil and things are not perfect. The description of the summer solstice at the beginning of the story symbolizes the light of our consciousness and that it shines more brightly when we are aware of it. The horses symbolize power, grace, beauty, strength, freedom, and nobility. These things could also describe the citizens of Omelas as well. The author describes the people in town in ways that make it seem like they are cheerful people. It talks about the children playing and the people celebrating during the ceremony. This makes it seem like they are happy people. “Their manes were braided with streamers of silver, gold, and green. They flared their nostrils and pranced and boasted to one another;......

Running Away from Home

...Running Away From Home When I was young, I tried my best to run away from home one time. Also, at that time, I finally understood another sense of home. Running away from home not only gave me an experience in my life but also let me understand how important my home was, and what I would need in my future. Running away from home happened in the summer that I just graduated from middle school in my small hometown—Shilou. Because of the hot and humid weather that summer, because of my boredom, or because of the nervous emotion of waiting for the notification from Shilou High School that I applied for, I always fought with my family member. One day, I fought with my brother because of the computer. I tried to complain about this to my mother, but I never get what I want. My mother always asked me to indulge my brother because I am older, I needed to show love to him, and I cannot be willful like him. I felt it was unfair, so I began to argue with my mother. Finally, I just ran back to my room, locked myself inside, and cried for a long time. My mother called me for lunch, and my brother gave up the computer and went outside. Even though they tried to do something to make me feel better, I still could not make myself calm down. At that moment, I was thinking if I lived without my brother, I would not need to indulge him anymore. I could live independently; I could do whatever I want. I began to think about leaving this unlovely home, and I began to plan to run away from......

Biome

...The Arctic and subarctic regions Compared with other biomes, the tundra biome is relatively young, having its origin in the Pleistocene (1,600,000 to 10,000 years ago). Individual plant and animal species of the tundra, however, probably first appeared in the Late Miocene (11.2 to 5.3 million years ago) or Early Pliocene (5.3 to 3.4 million years ago). Coniferous forests were present on Ellesmere Island and in northern Greenland, the northernmost land areas, in the mid-Pliocene (2.5 million years ago). Most paleoecologists believe that tundra flora evolved from plants of the coniferous forests and alpine areas as continents drifted into higher and cooler latitudes during the Miocene (23.7 to 5.3 million years ago). The Antarctic region Antarctica has been isolated from other continental landmasses by broad expanses of ocean since early in the Tertiary Period, about 60 to 40 million years ago. Prior to its separation it existed, along with Australia, South America, peninsular India, and Africa, as part of the landmass known as Gondwanaland. This long separation has impeded the establishment and development of land-based flora and fauna in the Antarctic. Other significant factors that have hampered terrestrial biotic evolution are the harsh climate, the ice cover that completely engulfed the continent during the Pleistocene glaciations, and the present limited number of ice-free land areas, which are restricted primarily to the coastal fringes and nunataks (mountain peaks......

Moving Away from Home

...the past I came across many changes but leaving my country was the toughest change in my life. I had to learn how to live away from people I love and how to start a new life in a new country. Immigration is a life changing experience; learning a new language, adapting to the culture and lifestyle changes are all strenuous things that were thrown at me once I became a part of this country. Even though moving away from my family and friends was a difficult decision, it changed my live for a better. It taught me how to deal with change, how to become an independent and responsible person, and how to feel this country my home. I never imagined living in another country. I remember as it was yesterday when my mom said, “Daniela, I know you do not want to leave Colombia but I have to take you with me, you are my youngest child and I will not let you here” I started arguing with her, saying that how she could do that to me when I already had plans to start college and that I was happy in my country but at the end I gave up and decided to come to America. It was February 10th, 2010, when I left Colombia and was forced to leave my friends, my grandmother, my school, my language and culture to move to this big new country to start a new life. As I took my last look at my home, I remembered all the fun times I had with my mom and sister and friends throughout my life. Tears were running down my face and I just started thinking about how I was going to leave my house, my......

A Home Away from Home

...Jessica Ganzermiller ENG101 Kambui 3/21/11 A Home away from Home I was ready or as ready as I could have been to take on the twenty six thousand detainees of Camp Bucca Iraq, the largest detention facility in the world. As I stepped off the plane; suddenly hit by the nearly unbearable One hundred forty seven degree heat. My boots were tightly laced ID tag on my left and Boot knife on the right. Eighty pounds of protective gear; Bullet proof vest with survival tools and pouches of ammo strapped to the front, helmet with my name and blood type so if my head were to blown off the would know it was mine, my ruck sac strapped to my back full of the bare essentials; weapons cleaning kit, 2 uniforms, hygiene items, extra boots, a sheet, a towel and a wash cloth; ready for a mission I had been trained for, but little did I know all the training in the world could not have prepared me for what I was up against. In fear I could not help but to wonder if this flight had been my last. This was going to be a fifteen month trip that would change my life forever. This was not just a mission assignment for the military; it was my personal road to self- discovery. We arrived in Kuwait; this place was not like any place I had been before. The fine sand whimsically disappeared as the drifting air carried it away. One place that had once been a place of calm reflection; was now a place where war death and hatred lurked in the air. “Formation” yells my Platoon Sargent in his newly pressed......

Break Away from Perfection

...Kaitlyn Grubb February 18, 2013 English 015 Rhetorical Analysis Break Away from Perfection Fresh, salty air succumbs every small crevice of your body. A sun drenched angelic beach stands in front of you, waiting to be discovered. The sunlight glitters on every grain of sand, revealing miniscule specks of gold beneath the surface. This beach is so innocent, so white, and so pure. The beautiful, enormous ocean waves are crashing against the cliffs as you watch the seagulls joyfully fly around in circles. Warm, golden sand runs between your toes while the gentle breeze glides through your wavy hair. Gorgeous, shiny shells are washed along the shoreline by the rippling of the water. This moment is absolutely breathtaking, and you cannot help to feel amazing in your white, strappy bikini. But suddenly, you are woken up from this magnificent dream and violently brought back to reality. You can no longer sit and enjoy this heavenly view, especially in that white bikini. The time has come…to change your tampon. Tampon commercials have become dull and misleading. The concept of that “time of the month” is now construed to be a glorious time, filled with love and beauty. Dancing, exercising, or running along the beach wearing white is just some of the many aspects of the hundreds of unrealistic commercials for feminine products. Fortunately, there is a new, daring brand that emphasizes the key trait of being honest and realistic. The Kotex brand brings a fresh life to tampon......

Far Away from Here

...http://nyti.ms/1Kv55ax Far Away From Here In travel photography, as in writing, there's no shortcut to finding your own voice. By TEJU COLE SEPT. 23, 2015 Only a few slender strings were attached: two public readings and a commitment to spend the majority of the six months in the country. Beyond that, I would be left to my own devices. An apartment would be provided, and a stipend. I didn’t think about it for very long. I wrote back: Yes. The invitation had come from the Literaturhaus in Zurich, one of those wonderful arts institutions of which Europe seems to have so many. Every six months they selected one writer, from anywhere in the world, to stay in the apartment they ran with a foundation. When I received the invitation, I felt as though I’d won a raffle I didn’t even know I had a ticket for. Switzerland: The place comes with an easy set of mental associations. But I suspected there was more to it than its reputation for calendar-pretty landscapes, secretive bankers and regular trains, and here was a chance to see for myself. Besides, I had a manuscript to work on, a nonfictional narrative of Lagos, Nigeria, the city in which I grew up. Where better to write about chaotic, relentless, overpopulated Lagos than in modest, quietly industrious Zurich? There would be so little else to do in Switzerland anyway (according to my less-than-enthusiastic friends) that I would be mainly absorbed in writing during my time there. Perhaps I might even......

...[pic] Away From Her Unit Assignment I. Summary of Movie A. Give a summary of the plot and characters and the story that unfolds in this movie. Give a detailed description of the main characters’ personalities, culture, socioeconomic and historical contexts, their relationships, set the stage of “who they are’ when the movie begins, and then tell the story of what happens over the course of the film. Away from Her is a motion picture designed to depict a realistic story of the challenges individuals must face when a family member is diagnosed and is experiencing the effects of Alzheimer's disease. The onset of the film describes the lives of Fiona and Grant Anderson, who had been married for over forty-four years. They lived in Fiona's grandparent's home in Ontario for most of their marriage, and shared similar interests in their hobby's and lifestyle. The movie progresses by depicting their routine ski trekking on a frozen lake and casual readings together. The purpose of depicting aspects of their everyday life was to enhance the sharp contrast in Fiona's behaviors as her Alzheimer's progressed. At first, Grant believed that her moments of forgetfulness were just that, but the occurrences became more drastic over time. The turning point that clearly demonstrated Fiona's Alzheimer development was her wandering across the forest in the freezing cold, where Grant had to drive around town to find her looking at the sights over a bridge far......
