A-Level Geography revision: Hazards and Global Issues. Learning objectives, key points, worked examples and practice questions across AQA, Edexcel, OCR, WJEC and CCEA.
📌 Key Points
Key Fact: Tectonic: plate boundaries; Climatic: atmospheric; Geomorphological: slope failure
Key Fact: Risk = Hazard x Vulnerability / Capacity to cope; PAR model (Pressure And Release)
Key Fact: Evidence: Keeling curve, IPCC reports, proxy data (ice cores, tree rings); GHG: CO₂, CH₄, N₂O
Key Fact: Impacts: sea level rise (thermal expansion, ice melt), extreme weather, biome shifts, ocean acidification
Key Fact: Adaptation: adjust to effects (sea walls, drought crops); Mitigation: reduce causes (renewables, reforestation, CCS)
Key Fact: Paris 2015: <2 deg C, pursue 1.5 deg C; NDCs; climate finance; Loss and Damage; CBDR (common but differentiated responsibilities)
🎯 Learning Objectives
- Classify hazards: tectonic (earthquakes, volcanoes, tsunamis), climatic (storms, droughts, heatwaves), geomorphological (landslides)
- Analyse hazard risk: probability x magnitude x vulnerability; risk equation
- Explain climate change: evidence (ice cores, temp records), causes (anthropogenic GHG), impacts (sea level, extremes, ecosystems)
- Evaluate management: prediction, preparation, prevention; adaptation vs mitigation
- Understand global governance: Paris Agreement, UNFCCC, Sendai Framework, climate justice
💡 Worked Example
Exam-Style Question
Question: Explain why vulnerability is a key component of hazard risk
Model Answer:
Same magnitude earthquake: Haiti 2010 (M7.0, 230k deaths) vs Chile 2010 (M8.8, 500 deaths). Haiti: poor building codes, dense informal housing, weak governance -> high vulnerability. Chile: strict codes, preparedness, wealth -> low vulnerability. Risk depends on vulnerability not just hazard
