Beaches are coastal landforms that are constantly changing. They are the result of wave action by which waves move sand or other loose sediments and compact and settle in still water. Beach materials are the products of weathering and erosion of rocks offshore, coral reefs and of headlands. Sediments may also be river-borne through the process of coastal erosion. Once compacted, the accumulated sediments are more resistant to erosion. Vegetation establishes shortly after, and their roots will also help resist erosion by slowing the fluid flow at the surface layer. Figure 1. Beach Morphology. The basic morphology of a beach is shown in Figure 1. A berm is a long narrow wedge of sand with its slope towards the water. The berm crest is the highest part of the berm where the sediment builds up and the waves do not pass. The tide …show more content…
There is high wave frequency and weak swash, which brings ashore a minute amount of material. Destructive waves tend to be tall waves, meaning they break with great force upon the beach leading to a strong backwash that removes beach material. Ultimately, destructive waves create steep narrow beaches. Constructive waves on the other hand have long periods between their wave crests and low energy. Their swash is much stronger than their backwash, building up the beach with deposited sediments. Constructive waves are long waves and roll on to the beach rather than crashing. Ultimately, constructive waves create wide, gently sloping beaches (Figure 2).
The beach profile undergoes seasonal changes due to change in wave energy. In temperate areas, summer beach profiles are characterized by: calm seas, long periods between breaking wave crests, and increased deposition thus high beach profiles. On the other hand, the winter months have amplified wave energy and increased sediment suspension thus lowering the beach profiles. In tropical areas, this phenomenon is in
Collaroy-Narrabeen beach is a beach located on Sydney’s coast and is managed by the Warringah council and is Sydney’s 2nd longest beach at 3.6km. The beach is the most vulnerable beach to erosion from coastal zones in Warringah and comes in at 3rd place in being the most at risk area from coastal processes in Australia. Warringah council however has put in a range of measures to lessen coastal
Beaches are sand, and sand comes from quartz, which is one of the hardest and most plentiful minerals on the planet. This sand was made when the ice sheet would expand and retreat picking up chunks of rocks, and mineral crushing them together effectively making a grinder in the glaciers innards (DNR). Sometimes these rocks and minerals are carried hundreds of miles before being deposited onto the ground. Michigan has a unique coastal landscape dotted with beaches and pine forest, but one thing that Michigan has; that not many places around the world have is bluffs. According to the National Geographic, a bluff is a small, rounded cliff that usually overlooks a body of water, or where a body of water once stood.
The winds help pollinate endangered plants, the currents helps shift minerals out and takes minerals in, shifting it around to different
“Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers” ( Megan Forbes, 1). Odysseus has obtained Poseidon’s wrath, and number one rule is to not
The waves calm you down after a stressful day. The view of the sun diving into the water at night would be so beautiful. The warm sun beating against your feels like entering a sauna on a cold winter day skin as you are swimming amongst the waves. Birds soaring above the water like planes soaring above the land. Seagulls come to play in the sand too.
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.

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.
A tsunami is a series of great sea waves caused by an underwater earthquake, landslide or volcanic eruption. A tsunami is a series of many waves known as wave trains. A tsunami can also be generated by a giant meteor. Most tsunamis are known to be formed by underwater earthquakes.
In the NY Times article “Why the Beach Is a Bummer,” Roxane Gay exploits the beach and the ways it never actually lives up to the expectation many have when summer comes around. Gay speaks of her childhood on the beaches of Haiti and how beautiful it was, but how different it is in the United States because there's such a high expectation for the beach since many areas aren’t surrounded by them. “The beach becomes a kind of utopia — the place where all our dreams come true”(Gay), meaning the beach becomes romanticized by so many when in reality there’s just sand in places where it doesn't belong whether in your book or on your body. Gay expresses how soon after arriving at the beach boredom approaches from having nothing to do besides

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.
Waves are created by local and offshore winds and other meteorological phenomena. There are two types of surface waves called wind waves and swells. Wind waves are generally steep with a short period and most of the time crests break in deep water. Swells cause from storms distances from the coast. Swell have a long, smooth surface and these waves never break in deep sea.
