sediment that lied parallel to the coastline and are separated from the mainland by a shallow sound‚ bay or Lagoon. Most barrier islands are along trailing edge and marginal sea coast where continental shelves are wide and gently sloping. The majority of the barrier islands in North America are along the Atlantic and Gulf Coast. The formation of the barrier islands is not fully understood. There have been many theories about their formation‚ but the current one states that barrier islands were formed

The coastline I have chosen is part of the world heritage site (the Jurassic Coast)‚ from Old Harry Rocks to St Oswald’s Bay Discordant Coast - the structure and alignment of these rocks have a significant effect on the landforms produced. This is a discordant coast where the geological sequence has produced distinctive coastal landforms. At Old Harry/Ballard Point and at Durlston Head are outcrops of rocks resistant to erosion.

Part 1 The geographical processes that are occurring at the Terrigal beach area are: * Erosion‚ which is effecting: * The Skillion‚ mainly the headland and rock platform‚ which is part of a preserved area of land known as “the Haven” which also contains the rugby oval. The man type of erosion that affects this is from the sea. * The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present.

can feel the sand being washed out from under your feet. The sand being washed out from under your feet as the waves wash over your feet is an example of wave erosion. Waves cause a type of erosion. This type of erosion is most often seen at the coast or along the edges of rivers and waterways. The velocity of waves are affected by slope‚ discharge‚ and shape of the channel of the waterway. Erosion is found on all coastlines in the world. The effect of wave erosion can last up to millions of

When they feed on the vegetation it is called eat-outs which end up making “openings in the marsh vegetation‚ and they are currently affecting an estimated 100‚000 acres of coastal wetlands” (“Nutria‚ Eating Louisianas Coast” 1). Most of the wetlands were “converting to open water at a rate of 25-35 square miles (65-91 square kilometers) each year” (“Nutria‚ Eating Louisianas Coast” 1). At this rate‚ the
