7.3 Questions

1. Erosion, Transportation and Deposition
2. As waves approach the coast they refract and bend due to headlands and the ocean floors contour. Wave refraction causes the wave energy to be concentrated in particular areas and less than others.
3.  
4. Beaches and Coastal Dunes
5. Hydraulic Action, Corrasion and Corrosion.
6. The accretion cycle is the cycle of is the formation of sand dunes due to decomposition of sediments.
7. Wind, Transportation and Erosion
8. Beaches
9. Coastal dunes are formed by wind. Sand is deposited on the beach and the wind blows the sand inward. The sand is then trapped by low lying vegetation and coastal spinifex. The pile of sand then becomes a foredune, which could then be eroded away or keep growing.
10. Longshore drift moves sand along the beach in a zig-zag movement.
11. Depositional landforms

Beaches

Dunes
Erosion Landforms

Badlands

Gully
12. The foredune provides a buffer zone for the fragile dune vegetation located on the hind dunes and so provide vital protection for property from erosion.

Cribbar Waves Profile

The Cribbar, also known as the Widow Maker, a name given to it after leaving many surfers injured after falling from their surfboards as they surfed these enormous waves, is a reef off the coast of sunny Cornwall, United Kingdom. The Cribbar is best known for its big waves that attract big wave surfers from across the world.


The waves won't break unless there's at least a 6-8ft swell and it can hold waves in the 25ft+ range. These waves are undoubtedly big but lose speed and power as they approach the shore, which leaves them behind other big waves around the world. These  Cribbar waves were first surfed by American surfer Jack Lydgate in 1966.

1. The pressure of urban development along the coastline has caused a range of geographical issues involving  various groups. Residents, tourists and commercial activity all need to be managed by geographers so that the development of the coastline is sustainable.
2. The sustainability of the coast is the primary concern as it is constantly under threat from pollution and over population.
3. Over development and rapid growth of coastal areas occur due to the current Australian trend for people to move from large cities to smaller coastal towns and villages where the lifestyle is more relaxed, and as such this is known as 'sea change'
4. One response to 'sea change; is the residential population caps that have been put in place so the coastal areas do not become overpopulated.
5. The four areas I have chosen 

Page 113 Questions

2. Farm area's increased, but the number of farms decreased
3. Rural recession, Soldier Settler blocks unable to turn a profit, Less farms
4. A lot of jobs that were previously manual are now mechanised and have been replaced by robots or machines instead of people

6. Population Decline, The Number of farmers and farms have decreased and less school enrolments

     8. The population has certainly dipped since the rural recession in the late 1960's and the town has never                 fully recovered

     9. More young  people are being born, but as they get older are leaving for better parts (mainly males)

Go Back To Where You Came From Reflection

• My initial reaction to the show is that of shock. My mother always tells me that immigrants are too well off and we are giving them everything and they are just taking our money and they should go back to where they came from, and for a while I believed that too. My view changed when I saw this film. After seeing the trials that these people go through, I can have some sympathy for the people coming here and what they had to do to get it.
• 1.5%
