COASTAL SYSTEMS AND LANDSCAPES DEFINITIONS De 0.0 / 5 ? GeographyDefinitionsA2/A-levelAQA Created by: hxudndjdCreated on: 13-04-18 14:27 78963452110 Across 1. Making a physical change to the coastal landscape using resistant materials, like concrete, boulders, wood and metal (4, 11) 5. Periodic rise and fall of the sea in response to the gravitational pull of the sun and moon (5) 9. Former glacial valley drowned by rising sea levels (5) 10. Waves with a high wave height with a steep form and high frequency. Their swash is generally stronger than their backwash so more sediment is removed than added (11) Down 2. Distance of open water over which a wind blows uninterrupted by major land obstacles (5) 3. Distinct area of coastline separated from other areas by well defined boundaries such as headlands and stretches of deep water (8, 4) 4. Coastline where strong, steady prevailing winds create high energy waves and the rate of erosion is greater than the rate of deposition (4, 6, 5) 6. Coastline where wave energy is low and the rate of deposition often exceeds the rate of erosion of sediment (3, 6, 5) 7. Waves with a low wave height but with a long wavelength and low frequency of around 6-8/min. Their swash tends to be more powerful than their backwash and as a consequence beach material is built up (12) 8. Wearing away of the Earth;s surface by the mechanical action of processes of glaciers, wind, rivers, marine waves and wind (7)
