Self-quizzing/exam skills- GCSE Coastal Landscapes Geographical terminology: You should know how to define these words You should know FOUR characteristics of each wave type (constructive/destructive) The impact of each wave type on beach profiles. The THREE types of weathering (physical/biological/chemical) The THREE types of erosion (hydraulic action/abrasion/solution) affecting the coast and Attrition affecting the size of beach sediment The TWO types of mass movement (soil creep/slumping) and how they affect the coast. Explain how landforms of erosion are formed in sequence and the processe(s) involved. Draw an annotated diagram to explain their formation. Describe the process of longshore drift and explain its impact on landforms of deposition. Draw an annotated diagram to explain the formation of landforms Define cliff recession. Explain the factors that cause differential rates of cliff erosion: fetch, geology (rock type and structure) and coastal management. Question type 1-Compare the characteristics of constructive and destructive waves. (4) 2-Outline the characteristic features of a destructive wave, (4) No question Explain the impact of constructive/destructive waves on beach profiles. Explain the process of physical weathering (3) You should include in your answer 1-Comparative statements: E.g. Constructive waves have a lower frequency (1) as a result of their longer wavelength (1) 2- Need some explanation/impact : e.g. Backwash> swash (1) therefore beaches eroded (1) High energy waves (1) due to greater fetch (1) Process for each type of wave: erosion/deposition and how they affect the gradient of a beach profile No question on erosion Outline how waves erode the coast Brief explanation of the three first types of erosion No question on soil creep Outline the process of soil creep. Outline how mass movement impacts on coastal landforms. (3) 4 mark questions on formation of: 1-Headlands and bays 2- Stack/stump 3- Cliffs and wave-cut platform Explain how geology influences the formation of coastal landforms (6) No question on bars and beaches and impact of LSD on deposition in estuaries. Outline two reasons for slumping and add e.g. Slumping causes a downward moment of material (1) this leaves a curved shape. (1). Need more than three ‘facts’ to answer this question 1-Outline how the process of longshore drift forms a spit. (4) 2-Explain the formation of a spit (4) No question on impact of coastal management. See disadvantages of types of coastal defences. NEW: 1- Explain why some cliffs retreat more rapidly than others. (6) (SP) 2- Outline how geology affects the rate of coastal recession. (3) 3- Suggest how wave fetch can cause different rates of coastal recession. (3) @KokkinosPat Geography is easy Explanation and cause/effect link All questions on formation: Sequence including change over time and process of erosion. Step 1 of sequence: What is needed for these landforms to form? E.g. Geology: Type of rock? Structure? Last step of sequence: Change over time 1- Answer centred on LSD. Explain process and link to spit. Last step: Over time build-up of spit as more sediment is deposited offshore. 2- Sequence of formation (see landforms of erosion) Step 1: Movement of material along a coastline due to LSD. Occurs where there is a change in direction of the coastline.(2) Last step: Formation of salt marsh due to spit protecting area from wave action.(1) 1- Explain at least 2 factors : Rock type/structure/wave strength(impact of fetch)/weathering . focus on why rates vary. Combine answers for questions 2 and 3. Explain how coastal recession affects people (human environment) and the environment. Use examples: THREE Effects on people: Happisburg (North Norfolk coast) for 6 marks THREE Effects on the environment: Durlston Bay for 6 marks Define coastal flooding. Explain how the effects of coastal flooding are reduced before the event through forecasting, building design, planning and education. Using examples, explain how coastal recession affects the human environment. (6) Explain how coastal recession affects people and the environment. Use examples in your answer. (6) Step 1- Define recession Step 2- Explanation of two or more effects To reach top level 3: good depth or detail, likely through locational detail. Add specific data from examples. For explanation: see reasons for coastal recessions at Happisburg 1- Explain how the effects of coastal flooding can be reduced through building design and planning. Use examples in your answer. (6) UK (HIC) Bangladesh (LIC) Define hard and soft engineering. Describe hard and soft engineering techniques used in the UK, including groynes, sea walls, off-shore reefs, riprap, revetments, beach replenishment, managed retreat and cliff regrading. Advantages and disadvantages of each technique and compare hard and soft engineering techniques. Explain how the coast is managed in a named location. 1- Compare the advantages of types of soft and hard engineering used on the coast. (4) 2- Explain the advantages and disadvantages of offshore reefs as a method of coastal defence. (4) 3- Explain how groynes protect cliffs from erosion. (3) Answer with a range (at least two) of specific and explained points which could be from different examples. E.g. In LICs coastal homes in areas prone to flooding are designed with stilts (1). Therefore when flooding occurs possessions are not destroyed as the water is able to pass below the home (1). 1- Use comparative sentences 2- Must explain e.g. Advantage: They break waves before they reach coast (1) Reduce wave energy before it reaches the coast(1) meaning less need for onshore protection (1). Disadvantage: They are not always effective in intense storms (1) therefore may need secondary support on the coast (1) 3- Groynes prevent LSD (1) therefore trapping sediment (1), thereby building a beach (1) The beach will absorb the wave energy and reduce erosion (1) Must have reference to erosion for 3rd mark For a coastal area that you have studied, explain why a variety of methods are used to manage the coastline. (6) Specimen paper For a coastal area that you have studied, explain why a variety of methods are used to manage the coastline. (6) @KokkinosPat Geography is easy Focus is on ‘why a variety’, suggesting that different areas need different methods. e.g. geology/ economic value of that area/section.) Focus is on ‘why a variety’, suggesting that different areas need different methods.
