Vegetated sand ridges called dunes, built up by dry beach sand blown inland and trapped by plants and other obstructions, back most beaches. As sand accumulates, the dunes become higher and wider.
Plants play a vital role in this process, acting as a windbreak and trapping the deposited sand particles. A characteristic of these plants is their ability to grow up through the sand and continually produce new stems and roots as more sand is trapped and the dune grows.
Stable sand dunes play an important part in protecting the coastline. They act as a buffer against wave damage during storms, protecting the land behind from salt-water intrusion. This sand barrier allows the development of more complex plant communities in areas protected from salt-water inundation, sea spray and strong winds. The dunes also act as a reservoir of sand, to replenish and maintain the beach at times of erosion.
Frontal sand dunes are vulnerable. The vegetation can be destroyed by natural causes such as storms, cyclones, droughts or fire, or by human interference such as clearing, grazing, vehicles or excessive foot traffic. If the vegetation cover is damaged strong winds may cause 'blowouts' or gaps in the dune ridge. Unless repaired, these increase in size, the whole dune system sometimes-migrating inland covering everything in its path. Meanwhile, with a diminished reservoir of sand, erosion of the beach may lead to coastal recession.
To avoid this, protecting the vegetation is vital. The beach, between high and low tides, is hard-wearing but the sensitive dunes, which we cross to reach it, must be protected also. For this reason damaged and sensitive dunes might need to be fenced and access tracks for vehicles and people provided.
Processes such as waves, near shore currents and tides continually modify shorelines. The ability of beaches to maintain themselves is achieved through these natural forces. The natural process of beach renourishment, sometimes called "dynamic equilibrium", is how the beach responds to weather. When waves are high during storms or when hurricanes hit the shore, sand is carried from the beach and deposited on the ocean floor. This makes the ocean bottom flatter and makes waves break further from shore and smaller. During subtle weather or erosion, smaller waves slowly shift the sand back to the shore and replenish the beach.

...ready spent almost $100 million to dredge sand from the ocean floor and dump it onto 33 miles of coastline. Ocean City Beach was renourished in 1982 for five million dollars, but washed away in only two and a half months.
When beach residents demand something be done about the beach dune erosion, and all the money the is spent on contemptible endeavors to stop mother nature, a storm or hurricane will come along and wipe out the development. Then billions of dollars are spent to rebuild coastline homes and resorts, which set up a repeating cycle of economic and environmental idiocracy.
One day, in a better society, we will save our beaches from development so that everyone is free to enjoy them in an unhampered, natural state. We will stop wasting billions of dollars in our futile attempts at man-made beach resurrection and pointless rebuilding of homes and resorts. It will become clear that the development of America's coastline is too costly to maintain and is destroying our beaches. Until then we will scurry to the tiny public designated beach access areas, fight for parking spaces and sunbathing positions, and enjoy one of our planet's most beautiful assets while we can.
There are many different types of coasts that exist throughout the United States. The south shore of Long Island has a unique types of coast known as a barrier beach. Barrier beaches are long narrow land forms that are composed of sand and other lose sediments. These sediments are brought together by the actions of waves, currents and storm surges. Barrier beaches are subject to constant changes by the same forces. Sand is constantly eroded in one area an deposited in another. Barrier coasts are important for a number of reasons; they protect the mainland of Long Island from the open ocean and flooding during storms, for recreational use and the unique ecosystems which exist on barrier beaches.
Concern On The Coast, Classical Conflict Again Unfolds: Energy vs. Environment." Hartford Courant 16 Oct. 2005, 3 Stars/Final ed., sec. A. Bigchalk Database. 8 Nov. 2005. Tedesco, Mark A. "This Fine Piece of Water:
Before human intervention, the coast of Collaroy was a series of sand dunes. The beach carried out its natural process and was undisturbed by human activities and construction. The beach has always had extensive sand dunes behind them, however this did not create negative impacts because it was a natural occurrence and there was no infrastructure intruding onto the beach. This is evident in Source A (found on the next page) a photograph, displaying Collaroy during the early 1900s.
To get to true equality, blacks must also be granted the power of the ballot. For it will liberate them and allow them to participate in the political process from which they were exempt from by whites. When blacks are able to vote for what is in the best interest of their black community then they will be able to improve their way of living. For years whites have decided what is in the best interest of blacks and Du Bois calls for an end to this system of dependency by granting blacks political power through voting. Du Bois states, “Negroes must insist continually, in season and out of season, that voting is necessary to modern manhood, that color discrimination is barbarism, and that black boys need education as well as white boys” (Pg. 47). Blacks must take action to pursue equality into the minds of white Americans. They need to be able to have the same rights as whites. Once blacks are able to get educated as the white man is able to, then they will be able to improve their place in society which whites have put them in. If blacks have the ability to get educated then they must be allowed to, based on their own free will to make their own life choices. In turn, society can prosper once true equality is sought
To accomplish this, Orwell utilizes the theme of individuality versus tyranny, foreshadowing, and irony, in order to fully extract all possible motives behind Winston’s actions.Many countries, such as the United States, are founded on principles of individuality reigning over tyranny, more specifically, the freedom of choice. However, in the futuristic Oceania, run by “Big Brother”, such freedom and individuality is, for the most part, completely suspended. To act impulsively, or choose to oppose Big Brother, is a “thoughtcrime” of dire consequence. This is the basis behind the Inner Party’s control of Oceania. Winston however, from the commencement of the novel, showed that he was not willing to conform to such a tyrannical society. From his writing “DOWN WITH BIG BROTHER” in his diary as the novel opened, to his relationship with Julia, which was considered sexcrime in Oceania, Winston proved his thoughts were antiparallel to those of the Inner Party.
Erosion is when the elements such as wind, water, and ice remove pieces of land. (“What is Coastal Erosion?”) Coastal Erosion takes place when destructive waves wear parts of the coast away. Four ways in which this takes place are corrasion/abrasion, hydraulic action, attrition, and corrosion/solution. (“Internet Geography”) Corrasion/abrasion is when materials are hurled at the base of cliffs through waves. Hydraulic action is when waves hit the base of a cliff and air is compacted, when the wave leaves air is rushed out and often this causes the material to break. Attrition is when the waves cause rocks and pebbles to smash into each other and eventually break into pieces. Finally, Corrosion/solution is when certain types of cliff erode from the result of acids in the sea. (“Internet Geography”) Coastal Erosion is the natural process of taking land away permanently from one place to put it somewhere else. (“What is Coastal Erosion?”) Eroding coastlines are an abundant and important topic because it can change people’s surroundings in a negative way. I would like to address the questions surrounding Coastal Erosion.
The 1920s are known as the Roaring Twenties, the Jazz Age, and the Golden Twenties. During this time, there were dramatic social changes in society. The Great War destroyed old perceived social conventions and new ones were developed. The 1920s was a decade that saw a great change in the role of women. The Roaring Twenties was a common name for the 1920s, due to the rise in consumerism and advertising at the time. Morals began to decrease during this time period. The 1920s was a period of time with great societal changes.
Semaphore Beach is affected by many factors such as natural processes and human impacts including marine litter and the discharge of stormwater. Therefore, several plans have been employed to ensure that the coast is supported through the method of counteracting erosion. However in the future, many management strategies have been put into consideration as well as the environmental, economic and social impacts as well as the predicted consequences. These impacts include traffic related incidents, noises and air pollution and the disruption of wildlife and the erosion of dunes. A method that should be considered for future management of the beach is the use of a concave sea wall, although efficient, this structure would be quite costly. Without the use of coastal management, Semaphore Beach would be unsupported, therefore negatively being affected by a variety of
Surfers, swimmers and sunbathers use beaches for recreation. People fish off beaches for food. Since many people take their vacations at the beach, lots of beaches in tropical locations are important to their country’s economy. Entire cities, regions and countries depend on the money tourists spend while visiting the beach. Beaches are naturally very dynamic places, but people try to control them and build permanent structures, such as houses, restaurants, shops and hotels, on or near the shore. The natural erosion and deposition of beaches becomes a problem. Beaches con disappear over time, or even over night during severe storms. Beaches are areas of loose sediment (sand, gravel, cobbles) controlled by ocean processes. Most beaches have several characteristic features. First are offshore bars, which help protect beaches from erosion. Next is the foreshore, which rises from the water toward the crest of the next feature; a berm. On low-lying shores, dunes form behind beaches. Dunes look like rolling hills of sand and are blown into place by the wind. New, smaller dunes are often changing shape as the wind continues to affect them. Waves and currents move the accumulated sediment constantly creating, eroding and changing the coastlines.
Abiotic factors are things that are nonliving that influence an environment and it's inhabitants. Some of the abiotic factors that are attributed to coastal erosion in Louisiana are hurricanes, tropical storms, elevation, sunlight, overnutrition, sea-level rise, and deposition. Hurricanes bring about larger waves which cause dune erosion or beach erosion (Clark et al., 1998). This is significant because beaches and/or the dunes of the beach serve as buffers to the coastline and the ecosystem. As the beach or dunes recede from the erosion caused by these large waves and an increased sea-level the flora and fauna that help sustain the area die off or retreat to a more habitable zone leaving the wetlands in a critical state often resulting in a total loss of the area (Stockdon et al., 2012). Due to the nature of the Gulf of Mexico large destructive storms such as hurricanes or tropica...
Freedom of speech allows other to express their own views and does not allow the government to intervene with others receiving such views. Just because an expression of an idea is not the same as the majority or it comes off as offensive does not justify it being illegal to say. Opposing view points are vital to the development of society ("First Amendment" 1). They encourage outside thinking and new ideas or revelations. It is free speech that has led to the advancement of society and will help to continue this process for many years to
Grandparents can have a big impact on how grandchildren make decisions in their lives. They usually either have a positive or a negative effect on their youngsters and sometimes in rare cases can have both a positive and negative effect. In my case I was fortunate enough to have two grandparents that both had a positive influence on me. The one with the biggest influence on me is my Grandpa Herb.
“For Many in the U.S, Grandparents are a Family Safety Net.” reads an August 2011 headline published by the Press Herald. This has proven true over and over again as grandparents are often considered the “glue “that holds the family together. These patriarch/matriarchs (regardless of age) offer priceless advice, leadership, and comfort in crisis situations. Their life experience, witt, and wisdom make for essential elements of the family unit. These individuals wear a variety of hats. In many situations, grandparents are forced; not by law but by affection and personal moral to take on the role as the primary caretaker of the child. This can be referred to as “kindship care “, a term describing the raising of an adolescent by close
This paper will give information about the reasons why grandparents are required to take care of grandchildren, positive effects of raising grandchildren, challenges of taking care of grandchildren, and what grandparents can do to help them cope.
This love relationship between Ammu and Velutha seems to be the only authentic love story in the whole novel. “He saw too that he was not the only giver of gifts. That she had gifts to give him too.” (pg. 176-177). This shows that they actually have real feelings for each other and just want each other for themselves and nothing more. The fact that both are from different caste systems, they don’t let this come in the way of their feelings. Ammu and Velutha only cares that they find happiness in each other and want to be together despite the Love Laws. These two have always been a rebel in everything they did. For example, Ammu knows that she is already a burden in her family as she is a divorcee from failed marriage with two kids. She has been breaking Love Laws way before Velutha came into her life. Also, Velutha being an untouchable shouldn’t even have the guts to
