Mrs. Davis Principles of Geography February 11, 2013 Aswan High Dam Aswan High Dam is located in the middle of the Egyptian Desert. This one of the largest embankment dams of the world. Known as Saad el Aali in Arabic, Aswan High Dam is one of the greatest engineering miracles of this world. The dam is 11, 811 ft long, 3215 ft thick at base and 364 ft tall. Aswan High Dam was built in 1960 to control the annual flood of the Nile River. This High Dam of Aswan provides irrigation facility and

There is an issue in society that continues to be a concern and needs to be seriously addressed. The problem is that global warming is increasing at a significant rate. According to NASA’s article entitled “Global Warming”, global warming is the unusual “...rapid increase in Earth’s average surface temperature,” (2014, para. 1). Our planet, Earth, has had its temperature changed a significant amount of times throughout history. These changes were due to receiving more or less sunlight from the shifts

sediment. The size of a glacier is dependent on its regime (balance between rate and amount of supply of ice and the amount and rate of ice loss). The glacier will have a positive regime when the supply is greater than the loss by ablation (melting, evaporation, calving, wind erosion). There will be a negative regime when the wasting is greater than the supply and the glacier is

Purpose The purpose of this experiment is to determine the energy level diagram of anthracene using its absorption and fluorescence spectra, as well as the quantum yield and rate constant of fluorescence quenching of antracene by CCl4. Methods A solution of anthracene and another solution of CCl4 are made in ethanol and mixed and diluted to various concentrations. The fluorescence and absorption spectra of these solutions are measured using a UV-visible spectrometer and a fluorescence spectrometer

Oxygen - A nonmetallic element constituting 21 percent of the atmosphere by volume that occurs as a diatomic gas, O2, and in many compounds such as water and iron ore. It combines with most elements, is essential for plant and animal respiration, and is required for nearly all combustion. Atomic number 8; atomic weight 15.9994; melting point -218.4°C; boiling point -183.0°C; gas density at 0°C 1.429 grams per liter; valence 2. Failures in the oxygen cycle within the hydrosphere (the combined mass

Definition of Terms A Action level The concentration established by the U.S. Environmental Protection Agency of copper or lead which, if exceeded, triggers treatment or other requirements that a water-supply system must follow. Acute criteria An estimate of the maximum concentration of a constituent to which aquatic life can be exposed for short periods of time without detri mental effects. Algorithm A systematic procedure (usually repetitive) for solving a problem. Alluvium A general term for

ranges from -27.2℃ to 7.0℃ which is a 34.1℃ difference (Climate-Data.Org). Although Iqaluit is near a body of water, I think the body of water won’t raise the quantity of precipitation because of the extreme cold temperatures that slows down the evaporation rate and the ice that is occupying much of ocean’s surface. Ultimately, it is a difficult decision to define Iqaluit as either maritime or continental climate due to the fact that this area is near a body of water but has features of a continental
