History of Eastern United States Coast Barrier Islands - Research Paper Example The Native Americans first occupied these barrier islands. They were later taken over by the European settlers for their recreational and touristic pursuits. However, they have diminished in size and retreated in the past years due to rising sea level, diminishing sediment, storms, and human interference. Extensive human settlement in these areas has raised concerns regarding the loss of habitat. Although vulnerable, these barrier islands are very important economically, serving as areas for tourist development, the source of food, and employment.

They usually create chains situated a number of miles offshore alongside the many passive margins. The back barrier region separates the barrier island from the mainland and shallow bays, marshes, estuaries, or lagoons usually occupy it. Barriers are created by the vertical accumulation of the sand from wind and waves action. Barrier islands are called so because they signify the shoreline natural protection from the forces of tsunamis, tides, currents, and waves from the core ocean. However, the majority of the barrier islands have been turned into resort-type living and beautiful beaches (Kusky 2008, 5). The development of the barrier islands characterizes one of the most dangerous trends in the coastal zones. This is because barriers are jutt ed mobile strips of sand moving in response to the changing storms, tides, coastal currents, and sea levels. Storms are able to move the complete sandy substrate out from the underneath of the tall buildings. Kusky (2008, 6) states that â€Å"the size of barrier islands ranges from narrow and discontinuous strips of sand that may be only a few hundred feet wide, too large islands that extend many miles across and also in length.† The length and the width are calculated from the existing amount of sediment and the balance between the tidal and wave energy. Majority of the barriers are built from sand (sand from the eroded coastal cliffs, deposited by rivers along the delta systems or sand left from the glaciations). Barrier islands are supposed to be discontinuous to permit water from the tidal changes to get back to the sea along the tidal inlets systems (Kusky 2008, 6). The sub-environments of barrier islands are classified the same as those of beaches. These sub-environment s include barrier interior, landward interior, and the beach. The beach face of the barrier is the most vibrant section of the island. It absorbs energy from the tides and waves and responds much like the mainland beaches. The beach backside of many barrier islands are marked by a foredune ridge or along frontal, followed landward by the secondary dunes.

Sociology class - Essay Example So what does sociology actually imply? For me, based on my own understanding, sociology is concerned with individual action that is unavoidably connected to the action and behavior of other people. Hence, the focus of sociology is quite extensive, encompassing all issues of our social behavior. Nevertheless, the abovementioned description of sociology can be confined. Take for instance an aspect of behavior like a consumer’s decision to buy a product. In general we would view this behavior as an economic act in the sense that it involves a monetary transaction. However the consumer’s choice to buy can also be regarded as being a sociological act, because it definitely has personal significance for the consumer, and it is directed towards the assumed and actual conduct of other actors such as salespeople, other consumers, etc. So what is the importance of sociology? Why do we have to learn about it? Sociology becomes increasingly important nowadays due to the sweeping progress of globalization. This event led to the far-reaching transformation of the globe’s political landscape. The traditional state was displaced by a completely new form of ‘nation state’ founded on transnational institutions, areas, and metropolises. Hence, because of this, sociology becomes indispensable to the understanding of the effects of globalization on the current standing of the nation state. However, some argues that sociology loses its importance because of globalization. I do not think so. Sociology will never lose its importance in present-day civilizations. While long-established societies and cultures were displaced by the new systems, a contemporary sociology embracing them displaced traditional sociology. Certainly, the similarity between traditional sociology and the contemporary one is that as the former emerged in reaction to contained modernization, observed through the occurrences of industrialization and, later on, urbanization, contemporary
