A.
A feature of coastal erosion is a cliff. The cliffs of Moher, Co. Clare are an example of this in Ireland. They are formed through the processes of erosion, hydraulic action, abrasion, compression and solution. At the base of the cliff a notch is cut by the wave action. The notch is enlarged by wave action between the high tide and low tide marks. A wave cut platform forms. An overhang is created. This overhang eventually falls into the sea. The debris is carried out to sea forming a wave cut platform. The process is repeated and the cliffs retreat.

B.
A feature of coastal deposition is a sand spit / tombolo. An example of this can be found at Sutton, Co. Dublin. It is formed by the process of long shore drift. Materials are dragged in a zig-zag manner up the coast by the action of the waves (swash & backwash). When the coastline changes direction, the materials are often deposited. A bar of sand will project out to sea as materials are dropped. Sometimes this sand spit connects to an island forming a tombolo e.g. Howth.



C.
(i) People use coastal areas for pleasure. Tourists travel to these places to enjoy the amenities that are offered at the coasts. Beaches are a major attraction, e.g. Brittas Bay, Co. Wicklow. There are usually opportunities to swim, sail and surf in these locations.
(ii) Tourists are also a major cause of pollution in these areas. Litter and sewage are a huge problem. Many beaches in Ireland have become polluted as a result of tourists being careless with their waste. Poorly designed infrastructure has also led to pollution from sewage, e.g. Courtown, Co. Wexford where raw sewage was pumped into the harbour as a result of an inadequate sewage system.
