1) Steel wire mesh filled with boulders used in coastal defences. a) GABION b) ROCK ARMOUR c) ROCK ARMOUR d) SEA WALL 2) A wooden barrier built out into the sea to stop the longshore drift of sand and shingle, and so cause the beach to grow. It is used to build beaches to protect against cliff erosion and provide an important tourist amenity. However, by trapping sediment it deprives another area, down-drift, of new beach material. a) ARCH b) BAR c) SEA WALL d) GROYNE 3) The use of concrete and large artificial structures by civil engineers to defend land against natural erosion processes. a) SOFT ENGINEERING b) HARD ENGINEERING c) SEA WALL d) MANAGED RETREAT 4) Allowing cliff erosion to occur as nature taking its course: erosion in some areas, deposition in others. a) TRANSPORTATION b) SEA WALL c) MANAGED RETREAT d) ATTRITION 5) Large boulders dumped on the beach as part of the coastal defences. a) ROCK ARMOUR b) ATTRITION c) LONGSHORE DRIFT d) DEPOSITION 6) A concrete wall which aims to prevent erosion of the coast by providing a barrier which reflects wave energy. a) ARCH b) DUNE REGENERATION c) SEA WALL d) SAND DUNE 7) Managing erosion by working with natural processes to help restore beaches and coastal ecosystems a) ABRASION b) BAR c) SOFT ENGINEERING d) GABION
