1. The factors are how long the fetch is, how long the wind has been blowing and how strong the wind is.
2a. The wind that will produce the largest waves is wind B because it has the largest amount of time and it is a strong wind and has the most distance to travel.
2b.The smallest waves will be created by a, and c because they are both light winds and they have the shortest distance to travel.
3a.Prevailing wind – the wind that blows most often; in the UK it is a south west wind (it blows from the south west.)
3b.The waves are very high because they have nothing close to them to make the waves slow down.
3c. I think that it is because they have great, high waves because of the large

I think that the Morston Marshes would get the least waves because it in in a bay and it is a marsh. The waves don’t have a long time to build up because it is a congested bay.
6a. A tide is the rise and fall of the sea level.
6b. The water would have been higher.
6c. The beach would have had more water and all of the space on the sand would have been filled with water. There wouldn’t have been as much space on the sand.
6d. I think that it was taken at high tide because there wasn’t much space on the beach and there wasn’t much sand.
7. Today, I went to the beach to look for whales. I thought I saw a whale, so I took a step forward to get a closer look. I didn’t see the crack between the two rocks and I slipped and fell down a hole. I couldn’t get out! The next thing I know, it was high tide! I was so nervous and the hole started to fill with water. There was no way I could get out and there was no way someone would see me. Next thing I know, the waves crashing at the back of the crack were so strong that they came back the other way and the strong current pulled me out of the hole. What an experience!

5a. Picture B or D could be used to illustrate the primary sector. I think that this is because they are making use of natural resources.
5b. Picture E could be used to illustrate the secondary sector because it produces manufactured goods.

6. Some of the jobs that people can do at the coast and sea but not inland are.
• Coastguard
• Lifeguard
• Fisherman
• Boat builder
• Surfing instructor
7. I think that the UK is one of the richest countries because
8. Some disadvantages of living near the coast include:
- Tsunamis
- Property getting smaller (coast being eroded.)
- Bad storms
- Water damage to property
- Salty air can lead to corrosion
- Floods
9. I would personally love to live on the coast because the advantages definitely outweigh the disadvantages. I love the idea of waking up in the morning and going for a nice walk on the beach. I love to go snorkeling and I love to swim. I’m not afraid of the ocean or anything living in the ocean so I would be out there everyday. I would prefer not to live right on the beach because of the land being eroded. Living one street down from the ocean would be best. Even though that land will still erode, it probably won’t in my
An increase in pebble roundness in the direction of long shore drift. The process of attrition will erode the pebbles. c) A decrease of pebble size in the direction of long shore drift, again attrition is involved. d) Undercutting (active erosion of the cliffs at one end of the bay).
[4.1] On average, how many high and low tides will a given spot on the coast experience in a day, and why?
Barrier Beaches stretch along the entire east coast of the United States. The barrier beaches from Long Island to Maine are known as Glaciated Coasts because their formation was assisted by glaciers. Eighteen thousands years ago a glacier covered most of the eastern US. This glacier terminated at present day Long Island. About fifteen thousands years ago the glacier began to retreat. As it melted it left behind mounds of rubble, called moraines. This particular glacier left behind two moraines because its final recession was a two part process. These two moraines are the Ronkonkoma Moraine and the Harbor Hill Moraine. The Ronkonkoma Moraine is located in central Long Island and the Harbor Hill Moraine is located on the northern part of Long Island. Besides the two moraines the glaciers deposited great amounts of debris offshore. This debris supplies the sand needed to create and maintain a barrier beach system (Hoel 16-18).
They also look after the quality of coastal waters by watering down, sifting, and settling deposits, left-over nutrients and contaminants. They are highly productive ecosystems and provide habitats and act as nurseries for all manner of life.
Salt marshes are coastal wetlands rich in marine life, which are covered by water at least once per month. They are found in the intertidal zones along low-energy coastlines, forming along the margins of estuaries, where freshwater from the land mixes with seawater. These marshes can be found near the Great South Bay and the Long Island Sound. The entire south shore of Long Island is considered to be a salt marsh important to the health of the marine life. Beginning in Jamaica Bay and extending to Montauk Point, Long Islands salt marches help remove toxic chemicals that are caused by pollution, thus making them a vital part of the eco-system.
1. How high will the waves get? Maximum wave heights (in feet) will not get any higher than * the wind speed in knots. This is correct over 90% of the time. Note: Wave height begins to increase when the depth of the water is less than or equal to 1/4 of the wavelength because the wave starts to touch the sea floor.
A longitudinal wave on the other hand is where the particles of the medium move in the same direction as the wave. Energy is passed along the air molecules through the lengthway vibrations of a longitudinal wave. This process continues throughout the entire wave, and t...
3- Secondary boom waves: It comes from sound firstly traveling away from the aircraft and then it’s reflected downward to far locations. Sound rumbles and can be quiet and difficult to

Destructive waves causing the largest wave cut platform in the Southern Hemisphere along Long Reef Beach
2. There is an anomalous result at 100cm. This is so far away from the
Waves can be described as a transfer of energy. They can occur in one, two or three dimensions, depending on the nature of the wave and medium. Waves can be classified as either mechanical or electromagnetic. Mechanical waves require a medium and can be either transverse or longitudinal. Electromagnetic waves do not require a medium and are all transverse. Figure 1.a. shows the image of a transverse wave, figure 1.b. shows the image of an electromagnetic wave.
Transverse and longitudinal waves can be compared and contrasted in regards to their wave parts as well as the different movements of particles and

• Entrapment of air by capillary waves - These waves have a very short wavelength and are produced by wind and surface tension at the air-sea boundary.
