Welcome back year 10!
Folders
• Name / Geographical Investigation / 10R
• Write your target grade & required mark:
A* = 34/36A = 32/36B = 30/36C = 27/36D = 23/36
Important:
Anyone getting above a C overall needs to get at
least 40/60 for their controlled assessments
Controlled AssessmentDue: 1st June
Fieldwork Focus : Coastal Management
“HOW DO GEOMORPHIC PROCESSES AFFECT YOUR CHOSEN STUDY AREA?”
Controlled assessment title
Important information
Location: Hengistbury Head, Dorset
Trip date: 25th April (compulsory)
Worth 36 marks, 15%
Workshops Wednesdays & during Easter/May half term
What can you remember about coasts?
Processes?
Landforms?
Management?
You will need to be able to do thignslike this:
Q: “With the use of a diagram, explain the process and effects of longshore drift” [4marks]

Types of coastal erosion?
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 into cliffs making rocks break and get smaller and rounder
Abrasion = ‘sand paper’ effect. Waves throwing small stones and pebbles at cliffs and beaches to smooth the material
Hydraulic Action = Power of the water forcing its way into cracks and weaknesses in rocks, splitting apart
The main landforms created by erosion are…
Headlands and Bays
What about waves?
If you were a wave, and you wanted to grow big and strong so you could 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
Example checklist
What does the markschemelook like?
How will you be marked?
Look at last year’s examples – peer assess
HOW DO GEOMORPHIC PROCESSES AFFECT 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 limit
Task:
• 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?)
Map 1: Ordnance Survey Map showing location details of Hengistbury Head
Key:
This area is already heavily defended with rock groyneswhich attempt to reduce the movement of beach material along the shore caused by longshoredrift
Mudeford Spit has been created by longshore drift and is a landform of depositino. It is mainly used for beach huts as seen in Photo A. The spit is important for tourism.
