Paper 1 tests your knowledge of the three global topics: Hazardous Earth, Development Dynamics, and Challenges of an Urbanising World. It is worth 37.5% of your total GCSE grade (94 marks in 1 hour 30 minutes). This lesson provides a focused revision guide covering the key content, case studies and exam priorities for each topic.
| Concept | What You Need to Know |
|---|---|
| Global atmospheric circulation | The three-cell model (Hadley, Ferrel, Polar); pressure belts; surface winds; Coriolis effect |
| Natural climate change | Milankovitch cycles; volcanic eruptions; solar output changes; evidence (ice cores, tree rings, sea-floor sediments) |
| Human-caused climate change | Enhanced greenhouse effect; CO₂ and methane sources; evidence of recent warming; consequences |
| Tropical cyclones | Formation conditions (27°C+ sea temperature); structure (eye, eyewall, spiral rainbands); distribution; impacts |
| Tectonic hazards | Plate tectonics theory; plate boundaries (destructive, constructive, conservative); earthquakes and volcanoes; distribution |
| Hazard management | Prediction, protection, planning; comparing responses in HICs and LICs; vulnerability factors |
| Topic | HIC Example | LIC/NEE Example |
|---|---|---|
| Tropical cyclone | Hurricane Katrina, USA (2005) or similar | Cyclone Nargis, Myanmar (2008) or Typhoon Haiyan, Philippines (2013) |
| Tectonic hazard | Japan Tohoku earthquake (2011) or similar | Haiti earthquake (2010) or Nepal earthquake (2015) |
For each case study, you need:
flowchart TD
A["HAZARDOUS EARTH<br/>Key Revision Areas"] --> B["Atmospheric Circulation<br/>Three-cell model, pressure belts"]
A --> C["Climate Change<br/>Natural + human causes, evidence"]
A --> D["Tropical Cyclones<br/>Formation, impacts, management"]
A --> E["Tectonic Hazards<br/>Plate boundaries, earthquakes, volcanoes"]
A --> F["Case Studies<br/>HIC + LIC for each hazard type"]
Exam Tip: The extended writing question for Hazardous Earth often asks you to compare impacts or responses between HICs and LICs. Prepare a table of key differences before the exam: building standards, early warning systems, emergency services, economic resources, governance quality.
| Concept | What You Need to Know |
|---|---|
| Defining development | Economic and social indicators (GDP, GNI, HDI, life expectancy, literacy rate); limitations of single indicators |
| Global development patterns | The development gap; North-South divide; emerging economies (BRICS) |
| Causes of uneven development | Physical factors (climate, resources, location); historical factors (colonialism, trade); economic factors (debt, trade barriers); political factors (corruption, conflict) |
| Development theories | Rostow's modernisation model; Frank's dependency theory; top-down vs bottom-up approaches |
| Strategies for development | Trade, aid, debt relief, FDI, microfinance, intermediate technology; advantages and disadvantages of each |
| Case study: emerging country | Detailed study of one country (e.g. India, Nigeria, or similar) showing causes and consequences of development |
You need detailed knowledge of one emerging country. Be prepared to discuss:
| Factor | What to Know |
|---|---|
| Location and context | Where, population, historical background |
| Economic development | GDP growth, key industries, trade patterns |
| Social development | Life expectancy, literacy, healthcare, education changes |
| Political factors | Government stability, democracy, corruption levels |
| International links | Trade partners, FDI, TNCs operating there, aid received |
| Inequality | Urban vs rural divide; gender inequality; regional disparities |
| Environmental concerns | Pollution, deforestation, resource depletion linked to development |
| Concept | What You Need to Know |
|---|---|
| Urbanisation trends | Global urbanisation rates; differences between HICs and LICs; megacities; urban growth patterns |
| Causes of urbanisation | Push factors (rural poverty, lack of services, natural disasters); pull factors (jobs, education, healthcare, entertainment) |
| Urban challenges in LICs | Informal settlements, inadequate sanitation, water supply, waste management, traffic congestion, unemployment |
| Urban challenges in HICs | Deindustrialisation, inner-city deprivation, housing affordability, suburban sprawl, social inequality |
| Urban management | Top-down approaches (government-led schemes); bottom-up approaches (community-based); sustainable urban living |
| Case studies | One city in a LIC/NEE + one city in a HIC showing challenges and management strategies |
| Feature | LIC/NEE City | HIC City |
|---|---|---|
| Growth rate | Rapid — often 3-5% per year | Slow or stable — often <1% |
| Main challenge | Informal settlements, basic services | Deprivation, regeneration, housing costs |
| Management | Often bottom-up; self-help schemes; NGOs | Often top-down; government investment; planning |
| Infrastructure | Overwhelmed; cannot keep pace | Ageing but functional; needs upgrading |
Exam Tip: For urbanisation questions, always distinguish between urbanisation (increasing proportion of people living in urban areas) and urban growth (increasing population of urban areas). They are related but different concepts, and using them correctly shows the examiner you understand the distinction.
Based on analysis of past papers, the following topics appear most frequently:
| High Priority (Almost Always Tested) | Medium Priority | Lower Priority (But Still Important) |
|---|---|---|
| Plate boundaries and tectonic hazards | Ocean currents | Quaternary period climate change |
| Tropical cyclone formation and impacts | Milankovitch cycles | Frank's dependency theory |
| Urbanisation causes and challenges | Trade vs aid debate | Natural greenhouse effect |
| Development indicators and the development gap | Rostow's model | Volcanic eruption processes |
| Case study impacts and responses | Urban management strategies | Pressure belts detail |
| Section | Topic | Marks | Recommended Time |
|---|---|---|---|
| A | Hazardous Earth | ~30 | 27 minutes |
| B | Development Dynamics | ~30 | 27 minutes |
| C | Urbanising World | ~30 | 27 minutes |
| — | Review | — | 9 minutes |
| Total | ~94 | 90 minutes |
Work through each section methodically:
| Mistake | Impact | Fix |
|---|---|---|
| Confusing natural and human causes of climate change | Muddled answers lose marks | Keep them separate in your revision notes |
| Using the wrong case study | Off-topic answers score poorly | Check which hazard/country the question asks about |
| Describing impacts without explaining them | Does not reach Level 3 | Always explain why impacts occur, not just what they are |
| Ignoring the resource in data questions | Capped marks | Always refer to and quote from the named figure |
| Running out of time on extended writing | Incomplete answers lose marks | Plan your time and stick to it |
| Generic answers without specific data | Cannot reach Level 3 | Learn specific statistics for your case studies |
Exam Tip: Keep a revision card for each case study with: name, date, location, 5 key facts (with numbers), impacts (primary + secondary), and responses (short-term + long-term). These compact summaries are ideal for last-minute revision before the exam.
