GeographyCoastal zonesGCSEAQA Created by: 10ruddlCreated on: 28-03-14 22:11 The top of a wave Crest 1 of 32 Where rock and soil is removed from the surface of the earth, often by wind or water. Erosion 2 of 32 Where the flow of water slows down, so sediment can no longer be transported. Deposition 3 of 32 All of the dune stages together. Psammosere 4 of 32 Allow low-value land to erode with minimal loss to property. Managed Retreat 5 of 32 Management using natural resources/processes Soft Engineering 6 of 32 Dip between waves Trough 7 of 32 Cliff slides and tilts, making a curved cliff. Slumping 8 of 32 The force of the waves compresses air in cracks and holes in the cliff, eroding it. Hydraulic Action 9 of 32 Certain rock types are slowly dissolved by acidic seas. Solution 10 of 32 The force of the waves make rocks smash each other into smaller rocks Attrition 11 of 32 Rocks 'sandpaper' a cliff/rocky platform. Abrasion 12 of 32 Management that is man-made/goes against nature. Hard Engineering 13 of 32 A hollow under a cliff caused by the waves eroding it. Wave-cut Notch 14 of 32 Where a cliff has collapsed into a gently sloping rock platform. Wave-cut Platform 15 of 32 Used to work out which management strategy to use. Cost-Benefit Analysis 16 of 32 Water goes up the beach Swash 17 of 32 Water goes back down the beach Backwash 18 of 32 Breakup or decay of rocks in their original place or close to the earth's surface. Weathering 19 of 32 Wood or rock barriers designed to prevent longshore drift , but can increase erosion in other areas. Groynes 20 of 32 Longshore drift combined with a change in wind/coast direction leaves an area of sand that sticks out from the shore which curves in on itself. Spit 21 of 32 Bits of rock and sand Sediment 22 of 32 Distance of open water where the wind blows Fetch 23 of 32 An area of land that sticks out into the sea, generally made of hard rock types. Headland 24 of 32 Less resistant rock has been eroded away, leaving a dip in the coast. Bay 25 of 32 The earth warming up due to increased amounts of carbon dioxide in the atmosphere Global Warming 26 of 32 Water freezing and thawing in a crack in a rock, increasing the size of the crack and eventually splitting the rock. Freeze-Thaw 27 of 32 Weak swash, strong backwash-erodes beach/cliff. Destructive Wave 28 of 32 Strong swash, weak backwash-builds beaches. Constructive Wave 29 of 32 Wire cages filled with pebbles which absorb the wave's energy. Gabions 30 of 32 Concrete or rock barrier curved to reflect the wave's energy-used to protect valuable land. Sea Wall 31 of 32 Putting sand/shingle on a beach to make it bigger, and not a susceptible to longshore drift. Beach Nourishment 32 of 32
