The Sandy Beach
The sandy beach and surf zones are two environments, which are usually
found along the edges of the sea. The sandy shore environment is made
up of sand and grains of rock and crushed shells while the surf zone
environment is made up mainly of water. Although the sandy beach zone
is said to be one of the most common environments along the shore, it
is considered a very harsh and dynamic environment.
Sandy beach shores usually have very harsh physical conditions. The
constant sand movement presents a problem for living organisms. These
organisms have nothing to hold on to, and have to either swim or
burrow rapidly or else they will be swept away by the water and the
sand. They also cannot live on the surface or live in permanent
burrow. This is why sandy beaches are hardly populated when compared
to other shores. In the sandy beach zone there are approximately 6 to
7 different species. However, although there is little diversity each
of these species may be millions in numbers.
The Upper inter-tidal zone consists mainly of dunes trees and
crustaceans. This zone has the widest range of heat and cold. Because
of this it also presents problems of heat in the summer and problems
with freezing for organisms in the winter.
The Mid-zone has similar problems with temperature as the upper
inter-tidal zone. This zone has more waves and therefore has rapid
sand removal during storms. Organisms such as the Pismo clam and spiny
mole crab live in this zone. The swash zone is where wave breaking
occurs. This zone has the highest water movement but does not have the
extreme temperatures, which the other zones have. The organisms that
live in the swash zone include the sand crab among others. Despite the
harsh conditions, which characterize this environment, sandy beach
shores, gives different number of habitats for organisms. Each habitat
or zone contains a particular group of organisms living in the zone.
For example the upper part of the beach contains a zone of plants such
Investigating the Geographical Processes that are Affecting the Physical and Built Coastal Environment There are three geographical processes that are affecting the physical and built coastal environment, they are; erosion, deposition, and transportation. Erosion is the group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from the earth’s surface, this is mainly caused by wind, running water, and waves breaking on the coast. Deposition is the depositing something or the laying down of matter by a natural process. Transportation is when sand is moved along the coast by long shore drift. At North Cronulla beach erosion is evident.
This shows that it is eroded at one end more which is a sign of long
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
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.

Section One - On the Beach Question 1: At the beginning Moira Davidson drinks a lot of Alcohol (alcohol). She is sad and angry because she can’t understand why the Australians have to pay for other people’s faults. John Osborne blames Moira to drink (for drinking?) too much to escape from reality.
Glacier Bay national park has three different types of climatic zones. Along the Gulf of Alaska coast, there tends to be more temperatures more mild with precipitation, but not much snowfall. In the upper region of the national park, there’s much colder temperatures with a lot of snow. The lower portion of Glacier Bay has more mild temperatures and is usually rainy throughout the year.
For example, zombie worms are very tiny. They are so small, they even lack a mouth and gut. They are red and pink in color. Giant squids are the opposite of zombie worms because they are extremely large. For example, they have two feeding tentacles which can be up to ten meters long, they also have eight arms that are all about half the size of their feeding tentacles. The feeding tentacles have hundreds of strong, toothed suckers and all arms have thousands of the same toothed suckers. The squid also has the largest eyes on earth, it has two eyes that are eleven inches in diameter. They are different colors, for example, at the surface of the ocean they are reddish orange or pink with spots of white and in the deeper parts of the ocean, they are silvery or gold. Yeti crabs are white or very pale yellow. They have hairy legs and chests and they measure almost six inches long. Each of these animals had to adapt to live in the sea and their appearances play a large role in this. For example, zombie worms don’t have a mouth or stomach, but instead they have skin cells that produce acid, the giant squids use their arms to catch prey and feed itself, and the crabs are able to survive in extreme heat and
Change in water temperature changes the places where grasses are able to grow, when fish and crab feed, reproduce, and migrate ("Chesapeake Bay Program"). The temperature in the bay goes from high in the summer to very low in the winter. During summer, the surface water is warmer than the deeper water which creates two different temperature layers that actually separate surface waters from deeper waters (“Chesapeake Bay Program”). The temperature layers change th...
In what ways does Carnegie believe that some people want things “for free” from the rich? Andrew Carnegie was an American industrialist, philanthropist, and business magnate who is best known for his innovative role in the steel industry during the late 19th century. Later in his life he was known for his philanthropy and philosophy about the moral obligation for the rich to use their wealth to benefit society. In his essay The Gospel Of Wealth, Carnegie speaks about the distribution of surplus wealth from the rich to society. Carnegie argued that it was not about giving things "for free" to the masses, but rather using wealth to create institutions and initiatives that would have a lasting and positive impact on society.
America has always been a land of great beauty and ambitious dreams. The most prominent dream of all is the American Dream: nice house, loving family, steady job. However, this vision is becoming less of a reality, and more of what it’s called, a dream, in this modern era. Through two different forms of art, poetry and music, two people describe their longing for a bit of the old world in this new one. “Dover Beach” is a poem in which Matthew Arnold laments the harsh realism that grips the world, wishing against all hope for romantic beauty to enthrall the world again. In the song, “Where the Green Grass Grows,” artist Tim McGraw expresses his longing for a peaceful, pastoral future, all the while describing his dissatisfaction of working in an increasingly gritty urban setting. The exploration of the effects contemporary society imposes on the beautiful, romantic dreams of the past are the centerpieces of the two different forms of art.

A new day has begun. Slowly ascending into the cold dark sky, the sun glows vibrantly with delight. The passionate colours fill the sky with warmth like the pink grapefruits, zesty lemons, citrus oranges and cherry red. The sea so subtle sparkles preciously as it strolls up against the shore. The crystal water that stretch out far into the horizon gets darker and deeper but stays very calm.
People from all over the world go to beautiful beaches that are filled with water as clear as ice or as beautiful as diamonds. But, what will happen if we do not conserve the appealing sites that draw attraction to the public? Contaminated beaches has become a controversial issue to the public because of the causal problem, the harm to the people and marine animals, the government agencies supporting or opposing pollution, and the industries involved in creating such unlawful decisions. To create and find a solution, we must first find the core to the problem.
