70 common limpets were identified in the 40m bracket identified as the littoral zone, between 0m to 40m. The common limpet employs a range of adaptations to survive the abiotic and biotic conditions associated with the littoral zone. Firstly, the limpet uses a structural adaptation to overcome the harsh wave action in the tidal zone, by using their radula to grip on to imperfections in the rock. Furthermore, they employ a behavioural adaptation of grinding their shells down into the rock, to further ensure they are not swept away by the tide. Additionally, the limpet utilises a behavioural adaptation regarding its tough shell and powerful radula, to defend against predators.
1997 New South Wales Landslide The landslide happened on 1997, July 30 in Thredbo, NSW at a village and ski resort late at night when most residents were in bed. Approximately 1000 tonnes of mud, rock and tress had fallen for a hill side of Alpine Way road which leads to a small ski town. The landslide had happened by pressure from really heavy rain, snow that has melted and transported weathered material. 2000 square metres of liquefied soil with a water flow of 1.7 litres per second took barely a few seconds to move 250 metres
Lake Huron on the other hand, has less dunes than Lake Michigan due to the fact that the western winds blow the sand back into the lake, making for a sandy bottom. Lake Superior has the only sand dunes on the Keweenaw Peninsula, which were blown in after the glacial departure. Glaciers may have played a large role in the shaping of Michigan but they were not the only foundation. There are actually three different groups of factors that cause erosion: terrestrial forces, aquatic forces and human activities. There are a handful of aquatic forces that have been a part of the shaping of
The shoreline disintegration brought on by Hurricane Katrina truly destroyed shorelines and whole islands. The ranges influence by Hurricane Katrina had as of now been debilitated by Hurricane Ivan a year prior, and the toll brought on by Katrina totally changed the scene. The Chandeleur Islands, off the shoreline of Louisiana, no more exist after Hurricane Katrina, and the celebrated beacon on those islands was decimated. Disintegration from Hurricane Georges in 1998 had already everything except pulverized the island, however they had improved when Katrina hit. Since Katrina, land studies have demonstrated that the islands are not changing.
Case 2: Chesapeake Bay watershed System Complexity, Data, and Impairment Description The Chesapeake Bay watershed is an example of a complex modeling system that consists of a large watershed (165,759 km2) with flow-regulated rivers, large urban centers and expansive rural areas, and an estuary (US EPA, 2010). The Chesapeake Bay TMDL allocates total nitrogen, total phosphorus, and sediment loads to reduce the size of the oxygen-depleted zones in the bay to restore its living resources. As such, estimating nutrient loads from all sources (air and land) and assessing their effect on the bay’s aquatic life requires the use of an integrated modeling framework. Because of the areal extent and system complexity of the watershed and the estuary, the Chesapeake Bay TMDL is one of the most complex TMDLs conducted in the United States.
When a wave moves over the sand on the bottom of the ocean the sand it picks up will settle in a different location building up. This process is also helped by the pull of rip currents and backwash. A barrier beach is simply a largely exposed sand bar made and kept by similar forces. Monomoy Island is a perfect example of a barrier beach. A barrier beach is made of primarily sand and is in constant flux.
With every journey comes a destination which is dependent on the degree of the individual and their will to potentially better themselves. A journey offers travelers the opportunity to extend themselves physically, intellectually and emotionally as they respond to challenges. Ruby Moon by Matt Cameron is a contemporary fractured fairytale in the form of a play that explores the grim, Australian legend of the missing child. This text portrays real issues in an absurd representation which forces the reader on an imaginative journey as well as the characters in an inner journey to establish an identity. Beach Burial by Kenneth Slessor is a distressing elegy about loss of life through war.
Vivid and memorable images produce certain emotions within the audience, through their interpretation of distinctively visuals to create particular perspectives. ‘The Shoe-Horn Sonata’ a multimedia presentation composed by John Misto, is a highly evocative play exploring the history and treatment of women in the Japanese prisoner of war camps, by looking at real life experiences of these women told through a story about two characters, Bridie and Sheila. Kenneth Slessor’s 1942 poem ‘Beach Burial’ similarly comments on the horrifying scenes of war and the significant sacrifice of those who fought. Through the use of distinctly visual techniques, both composers create memorable images immersing the reader into a new understanding of war allowing
The erosion process can increase or decrease in volume. Erosion is dependent on specific geological agents.
A storm surge is the rising of the sea as a result of atmospheric pressure changes and wind associated with a storm. Storm surges usually result in flooding in
Hard construction techniques can be seen as a traditional response to erosion that involves the construction of structures which defend against the erosive power of waves by stopping wave energy reaching the shore, or absorb and reflect that energy. However, this approach causes problems, whereby theses techniques tend to increase erosion in other places further down the coast, and thereby resulted in soft construction techniques becoming more popular because of this. On the other hand, soft construction techniques involves stimulating natural systems such as beaches and salt marshes which in turn protect the coast, and are relatively cheaper to construct and maintain than hard construction techniques, and at the same time be self-sustaining.

Neil Gaiman is a Hugo award winning British author of short stories, graphic novels, comic books, audio titles and films. Some of his notable works include ‘Stardust’, ‘Neverwhere’, ‘Good Omens’, ‘The Sandman’ series of graphic novels, etc. ‘The Ocean At The End of The Lane’ written by Neil Gaiman, is a book that is spoken through a child’s perspective, of the world around him. The book deals with the unstable emotions that the protagonist, a child goes through that eventually leads to a disconnect between his childhood and adulthood.
On The Beach (1959)- On The Beach, staring Gregory Peck, Ava Gardner, Fred Astaire, and Anthony Perkins, is one of director Stanley Kramer 's better (7/10 stars) works of of film. This motion picture is an alarming view of what a post-apocalyptic world would look like. The whole film is from the perspective of those people who avoided the destruction of functioning civilization. In the film Australia, more specifically Melbourne, has apparently "evaded destruction ", as it was spared complete obliteration.
The ocean… The sound of the waves applauding and hugging the shore. The internal sounds of the body out in the world’s biggest swimming pool. The echo of my sister’s laughter. The salty smell so strong that one can taste it dancing on ones taste buds.
Shallow earthquakes are between 0 and 70 km deep; and deep earthquakes, 300 - 700 km deep. In general, the term "deep-focus earthquakes" is applied to earthquakes deeper than 70 km. S-waves arrive as secondary waves at the Earth 's surface. There is another important difference between P-waves and S-waves.
