Exam Connection — OCR B Geography

🎯 Exam Connection — OCR B Geography

Paper: Paper 1 — Our Natural World (Component 1: Distinctive Landscapes)

Exam frequency: Very high — coastal processes and landforms appear in every OCR B Paper 1, typically combining process explanation, landform formation, and Holderness case study material.

Typical Question Types and Marks:

• "Describe and explain the formation of a wave-cut platform." [4 marks] — Requires the notch → overhang → collapse → platform retreat sequence. Two or three linked steps with the processes named (abrasion, hydraulic action). Level 2 requires the mechanism; Level 3 links it to factors that affect how wide the platform grows.
• "Explain one type of coastal erosion." [2 marks] — Name the process AND explain the mechanism. Hydraulic action: name it (1 mark) + explain the air compression and pressure release (1 mark). Naming alone = 0 marks.
• "Explain why the Holderness Coast erodes so quickly." [4–6 marks] — Structure around the CASE factors: soft boulder clay, high-energy North Sea waves, no beach protection. Level 3 requires you to explain HOW each factor contributes, not just list them.
• "Assess the effectiveness of one coastal management strategy." [6–8 marks] — Mappleton rock armour. You need: what was done, what it achieved, the costs (Holderness south), the sediment budget argument, and a supported judgement. Level 3 requires the judgement to be supported with specific evidence.
• "Describe the formation of a spit." [4 marks] — Longshore drift direction, coast change, deposition in open water, curved tip from wave refraction. Name Spurn Head or Hurst Castle Spit.

Moving from Level 1 to Level 3:

• Level 1: "Hydraulic action erodes the cliff." — Names the process but explains nothing.
• Level 2: "Hydraulic action erodes the cliff because waves compress air into cracks." — Explains the mechanism.
• Level 3: "Hydraulic action is particularly effective on the Holderness coast because the boulder clay contains many small fractures and bedding planes — the compressed air can exploit multiple weaknesses simultaneously, which combined with the lack of beach protection means the wave's full energy acts directly on the weakened cliff face." — Mechanism + location + interacting factors.

OCR Command Words for Coastal Questions:

• Describe: What does it look like? What features does it have? Use specific geographical terms.
• Explain: Why does it happen? Use "because" — link cause to effect using a process chain.
• Assess / Evaluate: How effective? Consider evidence for AND against; reach a supported judgement.
• Suggest: Use your geographical knowledge to give a plausible reason — no single correct answer.

Best evidence to deploy in any answer: HASA for erosion; Holderness 1.7 m/year; Mappleton protection scheme + sediment budget consequence; Spurn Head for longshore drift; Durdle Door or Old Harry Rocks for cave-arch-stack; boulder clay vs granite contrast for rock type.
