The Coastal System. The coast can be seen as a system in order to help to understand the processes and interactions involved. In theory, the inputs, processes and outputs work together to create coastal equilibrium. However, as we will see in this unit human actions affect the state of equilibrium within the coastal .
Coastal landscapes form cliffs, caves and arches. Land uses at the coast like industry and recreation and tourism can be in conflict with each other and solutions must be adopted to deal with these.
A geographer is interested in whether longshore drift is operating along a coastal spit at Abermenai Point in Anglesey. Random samples of pebbles were taken at the base of the storm beach at 15 sites every 50m along a spit. Here are the results.
UNIT 2 COASTAL ENVIRONMENTS Recommended Prior Knowledge As is the case for all the Advanced Geography Options, completion of the core modules is expected. The coastal environments option builds on knowledge and understanding gained in the compulsory core units of Rocks and Weathering. Context The focus here is on the link between process and form and the ways in which human activity is ...

Coastal defences built at Happisburgh have slowed down the rate of retreat. However, large sections are now in disrepair. Sealevel rise and climate change, including increased storminess, may also increase the rate of erosion. Agriculture and tourism contribute significantly to the economy of the village and surrounding hinterland although ...
Jul 06, 2014· The altering rate of erosion of hard and soft rock is known as differential erosion. As the bay develops, wave refraction around the headlands begins to occur, increasing erosion of the headlands but reducing the erosion and development of the bay due to a loss of wave energy.
This essay examines these processes and discusses the formation of two features typical of coastal erosion and two features typical of coastal deposition. Coastal erosion results from the interaction of four processes namely hydraulic action, abrasion, attrition and compression.
Attrition is a process in which mechanical tear and wear can break any rock mass into fragments. Mutual collision effected by backwash and r ip currents are powerful tools of coastal er osion.

What is erosion? Erosion is the wearing away of the land by forces such as water, wind, and ice. Erosion has helped to form many interesting features of the Earth's surface including mountain peaks, valleys, and coastlines. What causes erosion? There are many different forces in nature that cause erosion.

coastal erosion; Attrition the movement of waves makes rocks and pebbles crash together, so that sharp edges are broken down, and particles become smaller and more rounded. It affects boulders and stones that have already been eroded from the coast. Corrosion (solution) occurs when rocks are dissolved by sea water.
WaltonontheNaze is a small retirement town, located near Colchester via the A133 with a population of 40,000. Run by tendering local authority it relies mostly on tourism economically, which is one of the reasons they have a coastal management scheme which has recently been extended to the north to protect the luxurious houses situated there.

The term coastal zone is a region where interaction of the sea and land processes occurs. Both the terms coast and coastal are often used to describe a geographic location or region (, New Zealand's West Coast, or the East and West Coasts of the United States). .

Corrasion definition, the mechanical erosion of soil and rock by the abrasive action of particles set in motion by running water, wind, glacial ice, and gravity. See more.
These being those that form together on headlands, for example, caves, arches, stacks and stumps. We also look at the formation of bays and how they relate to headlands. We look at the processes involved in coastal erosion and then have diagrams which help explain the formation of the features involved.
The four main types of coastal erosion are Abrasion, Hydraulic action, Corrosion and Attrition. Abrasion / Corrosion Where sand and shingle are picked up by waves and scrap along the coastline
