Erosion Vocabulary Abrasion – erosion caused by wearing away of cliffs by sediment (sand, shells, rocks etc) flung by breaking waves Arch – wave-eroded passage through a headland Attrition –when rocks in the waves bump into each other and become smaller pieces Backwash – the return of the water to the sea after waves break on a beach Bays – bodies of water found between headlands where there are outcrops of harder rock and softer rock with the softer rock wearing away Beach – the temporary deposition of sand along the coastline – without it the coast is vulnerable Breakwater – offshore coastal defense structures Cliffs – hard resistant rocks higher than the surrounding area Cliff recession – cliffs worn away by erosion or wave action Corrosion – when the sea throws rocks at the cliff and breaks bits off Deposition – when sand and sediment is moved and deposited in another area Erosion – the wearing away of land and rocks by rivers, ice, wind and waves Fetch – the maximum distance winds can blow over water to their ultimate destination Groyne – wooden barrier built out into the sea to stop longshore drift Hard, resistant rock – holds headlands together Soft, less resistant rock – is worn away by erosion etc Headland – areas of land protruding (sticking) out into the sea Hydraulic action – water forces air into cracks into the rocks and the pressure builds until the rocks break Longshore drift – waves approaching the land at an angle cause the sand etc to move along the coast Prevailing wind – the direction the wind usually blows Solution – when salt in the water causes a chemical reaction in the rocks which breaks them down Stack – rock left standing out at sea after it has been separated by the mainland Stump – when a stack is worn away and gets smaller Wave attack – the movement and damage caused by waves breaking along the coast Wave cut platform – a rocky platform found at the bottom of an eroding cliff which is exposed at low tide Weathering (biological, chemical and physical) - breaking down rock Problems and Solutions What are the erosion problems that you can see above? (Describe what you see happening) How have humans contributed to this issue? What do you believe caused this level of erosion? (Be specific, what is happening at the beach that is causing this damage to happen?) Hint: Use scientific or subject specific language to support this eg: Hydraulic, wave type, backwash etc Who is this erosion problem affecting? Is this erosion benefitting humans or animals? If so, in what ways? What are the erosion problems that you can see above? (Describe what you see happening) How have humans contributed to this issue?
