mountains in this range is around 3,000 ft. The Appalachian Mountains are surrounded by valleys, which are better purposed for human occupation than other parts of the mountain range. As the top layers of the valley beds are made mostly of siltstones and shales, valleys are more easily eroded away than the tougher sandstone-covered ridges. A significant physical characteristic of the Appalachian Mountains are its ridges: two divisions of the range, the Blue Ridge and the Valley and Ridge, are…

“By the beginning of its second season, Saturday Night Live was the talk of television, a national sensation both hot and cool, and the first hit any network ever had at eleven-thirty on Saturday night” (Shales, Miller, 95). From young adults to the senile, Saturday Night Live has had people laughing for nearly forty-one years! This weekly show will go down in television history as one of the most iconic productions of the twentieth and twenty-first century. With every great show comes a great…

geologically varied with some rocks formed more than 3 billion years ago. It is composed of a metamorphic and igneous platform which is the foundation of the continent shield. On the top, different modern rocks such as sandstones, limestone, coal and shale laid down during the Devonian and Jurassic periods to form the Transantarctic Mountains (Adie…

Studant: Marcilene Macena Gomes Module Code: ECO119 Tutour: Shaun Bisheswar Semester 1 January 2018 Having being studding economy for the last four months I have learn a lot, made six tests and one presentation, for my last task of this semester I have being ask to answer three questions. First – in my words I have to search and show the difference between micro and macroeconomics. The second, describe the main policies instruments that a government or body can use to achieve macroeconomic…

as oil and gas are utilized for all heavy machinery, cars, plastics, to generate power and other equipment. With a sudden depletion or deficiency of a necessity society will collapse. The sources of the unconventional oil are tight deposits, oil shales, oil sands, and coal liquefaction. At current oil extraction rates, the peak oil extraction rate will be reached.…

Yosemite National Park was first protected in 1864 and has since been a fascinating landscape that can be observed by people from all over (NPS). The formation of Yosemite Valley has been a natural phenomena for millions of years, formed by some of Earth’s most compelling geological sources. Yosemite has many beautiful granite formations and glacier-carved landscapes that attract everyone from artists to geologists (Huber, 1987). Yosemite Valley was formed by a series of different forces…

Around 380 million years ago, during the Devonian Period, North America and Baltica collided. This collision created another mountain range located in the same place where the Grenville Mountains and Taconic Mountains were formed. The Acadian Orogeny happened on the northeastern side of North America. Like TIA and the Grenville Belt, there was another land piece between Proto-North America and Baltica. This land piece was called Avalon. Avalon was believed to have broke apart from…

While winter approaches, arctic cold fronts bring a decrease in temperatures to the prairies and the demand for heat and energy increases. Western Canada derives much of its main source of heating fuel from natural gas. It also leads Canada in the production of natural gas through unconventional well production. Natural Gas or Methane (NH4) left in its organic state, and let migrate in the atmosphere as is the case in the Arctic with the thawing of the tundra, is 20 times more harmful as a…

Keystone XL: A Pipeline Fueling Debate The Keystone Pipeline XL, a large pipeline that has been proposed to transport oil from the Canada to the United States, has led to controversy recently. Why is there so much debate, you may ask, when it has, “the support of an increasing number of Democrats, as well as the vast majority of Republicans in Congress” (Steinhauer, 2012)? There are many disputes between political parties and groups in the U.S., but what is special about the Keystone Pipeline…

OPEC produce roughly 40% of the worlds oil, therefore if all the remaining producers were able they would massively increase supply and decrease OPEC market share, with a big enough response the price of oil would approach competitive allocation. OPEC must therefore take into account non-members when setting the price. Salant’s model argues that due to the presence of a competitive fringe the cartel must set the price lower than the monopoly price, reduce output and let the price rise rapidly.…
