Folders• Name / Geographical Investigation / 10R• Write your target grade & required mark: A* = 34/36 A = 32/36 B = 30/36 Important: C = 27/36 Anyone getting above a C D = 23/36 overall needs to get at least 40/60 for their controlled assessments
Erosion is……. the wearing away of materials by one of four processes: Corrosion = chemical reactions of salt water weakening rocks like an acid Attrition = Pebbles hitting into each other or intocliffs making rocks break and get smaller and rounder Abrasion = ‘sand paper’ effect. Waves throwing smallstones and pebbles at cliffs and beaches to smooth thematerial Hydraulic Action = Power of the water forcing its wayinto cracks and weaknesses in rocks, splitting apart
If you were a wave, and you wanted to grow big and strong so youcould knock the UK’s block off, which direction would you come from? Why?
Waves• There are two main types of waves:• Constructive vs Destructive
So, the controlled assessment How does it work?
Example controlled assessments from last year• Take a look at what you will be producing• You will have prep time before the trip, then the trip on 25th April, then the analysis afterwards• Key things = keywords, theory, analysis, explanation, evaluation
What does the markscheme look like? How will you be marked?Look at last year’s examples – peer assess
HOW DO GEOMORPHIC PROCESSESAFFECT HENGISTBURY HEAD?
Mindmapping key questions• Break the essay question down into 3 or 4 key questions that you could investigate• Key questions are essential• Think up questions, think how you could answer them – what data would you need to collect
Key questions?E.g.• What it the location of Hengistbury Head? What is H.H. like…?• What are geomorphic processes?• What geomorphic processes are occurring at H.H.?• How are geomorphic processes changing the landscape?• What landforms are these geomorphic processes creating?• How are people/environment affected? (positive/negative)• Is there any evidence of coastal management to reduce the impact of geomorphic processes?
Prep for the intro: the location Where is Hengistbury Head? What is the location like?
Location maps• Essential skill• Key way to pick up marks – not included in word limitTask:• Annotate the O.S. map & satellite image of H.H. to show features, landforms, management, land use, etc.• What map evidence is there of geomorphic processes? (e.g. landforms? Management?)
