    1. CDunne/TYork (c)2008 Geography GCSE Revision Edexcel Specification A

    2. CDunne/TYork (c)2008 Getting Organised!

    3. CDunne/TYork (c)2008 Knuckling Down No way of getting away from it … you need to do this yourself – there’s no substitute for hard work. But congratulations, you’ve made a start – you’re here today and coursework is done and dusted! So, ideas for revising?

    4. CDunne/TYork (c)2008 Our suggestions Mind maps Create a glossary Create a PowerPoint! Make it interactive Write a quiz Check out S-Cool website

    5. CDunne/TYork (c)2008 The Course The physical course is used on both exam papers – 1F/3H Knowledge and skills 2F/4H How would you manage a physical environment.

    6. CDunne/TYork (c)2008

    7. CDunne/TYork (c)2008 Systems The hydrological cycle = a closed system No beginning, no end The movement of water between sea, atmosphere and land Draw a quick sketch to show: Precipitation Evaporation Condensation

    8. CDunne/TYork (c)2008 Systems II The Drainage Basin System = open system It is part of the bigger picture, the water cycle Can you name all of the terms and remember what they do?

    9. CDunne/TYork (c)2008 Ronny the Raindrop

    10. CDunne/TYork (c)2008

    11. CDunne/TYork (c)2008 Fluvial Processes – lots of important terms! Erosion (the wearing away of the land) and can be: headward vertical lateral Which means what? Main processes: Corrasion / abrasion – scouring Attrition – bedload knocks together becoming smaller and more rounded Hydraulic action – force of the water Solution / corrosion – the dissolving of rock

    12. CDunne/TYork (c)2008 Fluvial Processes – lots of important terms! Transportation: Traction – large boulders rolled along the river bed Saltation – small particles are bounced along the river bed Suspension – fine particles carried along by the river itself Solution – material is dissolved in the water Deposition – formation of deltas

    13. CDunne/TYork (c)2008 Landforms You need to know the formation of fluvial features with annotated diagrams I would suggest the following: Upper – waterfalls Middle – meander/oxbow lake Lower – flood plain / levees / deltas /estuaries

    14. CDunne/TYork (c)2008 Flooding a UK example of a case study Case Study: River Derwent, N. Yorkshire When: March 1999 Where: near Malton and Norton Causes: Unusually high rainfall in February prolonged rainfall in March (about ¼ of annual average fell!) snowmelt Geology – clay (Vale of Pickering only a few metres above S.L.) Consequences: Average flow of 22 cumecs increased to about 150 cumecs! Properties built on flood plains flooded – a 50cm water depth Train station flooded Schools shut Businesses closed temporarily

    15. CDunne/TYork (c)2008 Mississippi What are the top 10 things you must know without fail about this river and how it is managed? Remember it could be on BOTH papers.

    16. CDunne/TYork (c)2008 Flood Control and Prevention Use in both exams

    17. CDunne/TYork (c)2008

    18. CDunne/TYork (c)2008 Coastal Processes - Erosion

    19. CDunne/TYork (c)2008 Coastal Landforms Make sure you know how each one is formed … with diagrams!

    20. CDunne/TYork (c)2008 And a case study Use on both exam papers Holderness, Yorkshire (look at a map!) Most rapidly eroding coastline (~2 m / year) Since Roman times, 30 villages have been lost to the North Sea Coastal geology – easily eroded boulder clay Erosion also due to lack of beaches (shock absorber) and powerful waves A combination of management methods have been used, including allowing nature to take its course – what do you think the local response to this might be? What are they? Where are they based you have to include loads of detail to achieve a level 3 answer. But limiting coastal management at Holderness, means protection of larger settlements further south – how? Does this justify allowing erosion to happen?

    21. CDunne/TYork (c)2008 Walton-on-the-Naze What are the key points that this case study teaches you about cliff recession and management?

    22. CDunne/TYork (c)2008 Glaciation Paper 1F/3H mainly although it may be mentioned on the second paper Key Questions to answer: How are glaciers formed? How do Glaciers erode? What land forms can be found in glaciated valleys?

    23. CDunne/TYork (c)2008 How is a Glacier formed? Write an answer to this question Can you think of an illustration to visually aid your memory?

    24. CDunne/TYork (c)2008 How do Glaciers erode? How do glaciers which are cold, use heat to erode? What is this called? Which type of weathering is this? What is abrasion?

    25. CDunne/TYork (c)2008 What landforms are created? Explain with diagrams – how a Corrie, Arete and Pyramidal peak are formed. How can a U shaped valley develop from a V shaped valley? What is a truncated spur? Why does it form? Hanging valleys are difficult to explain – make a detailed drawing to show the before, during and after landforms, remember it is to do with speed of glacier movement. What is a ribbon lake? What is Morraine? There are at least 3 types, what are they?

    26. CDunne/TYork (c)2008 Case studies There are no specific case studies to quote but you need to be aware of areas which are glacial – Scotland, the Lake District, New Zealand, the Alps. Maps of all of these places have been used in these exam questions. Use the white skills books to help.
