Adelaide Coast (geography) essays

Adelaide Coast (geography) essays Describe and explain the variation of coastal type and of landform along a particular coastline. The length of the particular coastline you choose may be as little as two or three kilometres or as much as several hundred kilometres. The Adelaide metropolitan coastline stretches around 30 kilometres, from Seacliff in the south to Outer Harbor in the North. Whilst the southern end of the coast has notable erosional landforms such as cliffs, wave-cut platforms and shingle beaches, the vast majority of the coastline is depositional. This essay will focus on the depositional sandy beaches and dune systems found along the Adelaide coastline. Much of the Adelaide coastline is made up of wide sandy beaches. Beaches are formed when sand is brought on to the beach by waves. This occurs particularly in the summer months when waves are constructional, as seen in diagram 1. The profile of the beach changes due to tidal and waves variation. In winter, as seen in diagram 2, waves are deconstructional, and the beach profile is lowered, resulting in the formation of a berm. Off shore sandbars develop, and the sand returns to the beach again in summer. Sand is carried on to the beach by waves and along the beach by the movement of longshore drift. Longshore drift carries the sand along the shore in the direction of prevailing wind and is responsible for the build up of sand behind natural features such as headlands, and man-made features such as breakwaters. In diagram 3, the action of longshore drift is shown at Glenelg. Sand is picked up by the waves and moves along the beach in a zig zag motion. The breakwater interrupts the drift and sand is deposited, resulting in a wide sandy beach south of the breakwater, and a spit forming at the end, with North Glenelg being badly starved of sand. The same build up of sand south of the breakwater, and shortage of sand to the north occurs at Outer Harbor. This is because of Adelaides prevailing s ...

A Solution to the Growing Gas Prices in the United States.

A Solution to the Growing Gas Prices in the United States. Gasoline prices have been taking a sharp turn towards the worse. According to Hawaiigasprices.com, in Hawaii, gasoline can cost as much as three dollars and ninety four cents; in nineteen ninety-eight it was one dollar, seventy five cents. The recent spike has caused financial hardships and gas itself has had numerous harmful effects towards the environment. To resolve this problem, I urge you: Senators, to at least carefully consider the need for a resolution, but hopefully to pass my legislation for these reasons:(1) Gas prices have hit record highs in the past years.(2) The increasingly high gas prices are causing immediate financial difficulties.(3) The environmental tolls will over time have an extremely dangerous effect on society.As said before gasoline has been hitting record highs, and recent happenings (such as the shutting down of oil harbors in New Orleans and the continuing difficulties of the War in Iraq) have even further added to the financial burden of the people of the American society.Comparison of greenhouse gas emissions for municip...Just over half of the people surveyed in an ABC News Poll say that they are having these financial problems, and, magnifying the apparent decay of the economy, forty five percent of people say they're spending less and twenty one percent say they are having to resort to saving less, both in which will overtime damage the economy even faster. However, according to Iowa Corn, if the switch to E-85 is made, it is expected that over the next fifteen years, three hundred thousand new jobs could be created through the Ethanol base. Also, if a slow transition is made (one or two years rather than months) it should give foreign countries whose economy depends on oil sales to the United States adequate time to plan and begin working on other possible exports...

Changing Business Enviroments - Essay Example in the changing environments and argues that policies and practices have to keep pace with changing times and aspirations of the people. A policy focuses on a desired goal through a statement of intention. For example, a policy may state that inflation will be controlled to a level of 3% or that fiscal deficit will be contained to within 1% of gross national product, or that carbon emissions from power plants shall be reduced by 15%, during a particular period. Similarly, an automaker may declare a policy of achieving 75% level of outsourcing for its components, or business expansion through acquisitions etc. Thus policies, whether declared by a government or by a business, are statements of intention for achieving specific objectives, and act as beacons for concerned executives to follow up with appropriate actions. In Policy Analysis: A Political and Organizational Perspective William Jenkins states that a policy is ‘a set of interrelated decisions taken by a political actor or group of actors concerning the selection of goals and the means of achieving them within a specified situation where those decisions should, in principle, be within the power of those actors to achieve’(Jenkins, 1978). Thus while it is the prerogative of governments to set public policies, governments are goaded into action by the public while for a business it is the specified situations that trigger policy decisions. According to Miyakawa, a public policy is a culmination of a process - a process that examines various options for possible course of action on any specific issue for which there is a public demand, and these issues and demands generally arise out of the prevailing socio-economic situations (Miyakawa, 1999, Science of public policy, Part 12, p.3). Evaluation of options will lead to selection of a policy, implementing plan of actions in order to the achieve the objectives, and monitoring the results
