  • Curriculum Structure and Level of Study:

    • Key Idea 3.1 is taught in Year 1111.
    • Key Idea 3.2 is taught in Year 1010.
    • Key Idea 3.3 and its associated comparative case studies are taught across both Year 1010 and Year 1111.

  • Key Idea 3.1: Spatial Variation and Physical Drivers of Natural Hazards:

    • Hazard Characteristics, Distribution, and Measurement:
    • Covers natural hazards categorized under tropical cyclones, earthquakes, and volcanic eruptions.
    • Systematic tracking of the spatial and geographic distribution across global zones (e.g., coastal tropical belts, tectonic plate boundaries, and intra-plate volcanic hotspots).
    • Measurement scales and monitoring metrics utilized to calculate hazard intensity, magnitude, physical scale, and potential destruction.
    • Causal Mechanisms of Tropical Cyclones:
    • Ocean temperature requirements (warm sea surface temperatures necessary to fuel atmospheric convection and latent heat release).
    • Atmospheric pressure variations, particularly the establishment of intense low-pressure systems and steep pressure gradients.
    • Wind shear dynamics, including low vertical wind shear allowing storm clouds to build vertically without being torn apart.
    • Coriolis force, which provides the necessary rotational spin to organize spiraling weather systems, preventing tropical cyclones from forming directly on the equator (0∘0^{\circ} latitude).
    • Causal Mechanisms of Volcanic and Earthquake Hazards:
    • Tectonic plate boundary dynamics: constructive (divergent), destructive (convergent/subduction), and conservative (transform) margins.
    • Hotspots: isolated plumes of upwelling mantle magma independent of plate boundary margins that generate volcanic island chains and volcanic features.

  • Key Idea 3.2: Hazard Vulnerability and Multi-Hazard Impacts:

    • Human Settlement in Risk-Prone Regions:
    • Social, economic, cultural, and historical drivers influencing populations to settle and remain in zones prone to hazard events (e.g., fertile volcanic soils for agriculture, geothermal energy resources, mineral extraction, economic necessity, family heritage, or lack of relocation options).
    • Dimensions of Hazard Vulnerability:
    • Physical vulnerability: Geographic proximity to fault lines, low-lying coastal exposure to storm surges, poor structural integrity of local housing, and environmental degradation.
    • Social vulnerability: Age distribution (infants and elderly), population density, levels of literacy, education, public health infrastructure, and community awareness.
    • Economic vulnerability: National and individual financial wealth, levels of debt, quality of emergency services, insurance penetration, and capacity to withstand financial loss.
    • Comparative Assessment of Hazard Impacts:
    • Requires analysis of shorter-term (immediate) impacts and longer-term (secondary/chronic) impacts across three distinct natural hazard events:
      • One designated earthquake event.
      • One designated volcanic eruption.
      • One designated tropical cyclone hazard.

  • Key Idea 3.3: Earthquake Hazards, Management Strategies, and Case Studies:

    • Case Study Mandate:
    • Compulsory in-depth study of earthquake hazard management contrasting an event in a developed country with an event in either a developing country or an emerging country.
    • Pre-Disaster Earthquake Preparation:
    • Warning systems, early alert technology, and evacuation protocols.
    • Aseismic building design and structural engineering (e.g., base isolators, counterweights, reinforced foundations, and flexible materials).
    • High-tech spatial applications: remote sensing and Geographic Information Systems (GIS) for spatial vulnerability analysis and logistical mapping.
    • Short-Term Responses and Emergency Relief:
    • Rapid deployment of emergency aid, search and rescue teams, medical triaging, distribution of food and clean water, and temporary shelter provisions.
    • Longer-Term Hazard Planning and Mitigation:
    • Comprehensive risk assessment and detailed hazard zoning/mapping.
    • Sustained rebuilding programmes, retrofitting infrastructure, enforcing modern building codes, and community-wide economic and social recovery.

Paper 2 Question 1: Economic Activity and Energy

  • Curriculum Structure and Level of Study:

    • Key Idea 4.1 is taught in Year 1010.
    • Key Idea 4.2 is taught in Year 1010.
    • Key Idea 4.3 and its associated comparative case studies are taught in Year 1111.

  • Key Idea 4.1: Sectoral Employment Structures and Locational Shifts:

    • Classification of Economic Employment Sectors:
    • Primary sector: Extraction and harvesting of raw natural resources (e.g., agriculture, mining, forestry, fishing).
    • Secondary sector: Manufacturing, processing, and construction converting raw materials into finished industrial goods.
    • Tertiary sector: Provision of commercial, public, and personal services (e.g., retail, healthcare, education, transport, finance).
    • Quaternary sector: Knowledge-based and research-intensive activities (e.g., scientific research, information and communication technology, computing, development).
    • The Clark Fisher Model:
    • Conceptual model illustrating the changing proportions of sectoral employment over time as a country progresses through pre-industrial, industrial, and post-industrial stages of economic development.
    • Factors Influencing Economic Activity Location:
    • Spatial distribution factors across primary, secondary, tertiary, and quaternary operations (e.g., proximity to raw materials, energy access, transport infrastructure, market proximity, skilled labor pools, and land costs).
    • Evolution and alteration of locational factors over time due to industrialization, footloose industries, and digital connectivity.
    • Drivers of Sectoral Employment Shifts:
    • Availability and depletion of raw materials.
    • Globalisation and the emergence of transnational corporations (TNCs).
    • Mechanisation, automation, and technological improvements reducing labor demand.
    • Demographic changes, such as population growth, urbanization, and aging populations.
    • Government economic policies, enterprise zones, subsidies, and national regulations.

  • Key Idea 4.2: Economic Sector Impacts, Informal Labor, and Population Theories:

    • Impacts of Economic Sector Shifts:
    • Evaluation of both positive impacts (e.g., wealth creation, infrastructure upgrades, higher wages) and negative impacts (e.g., deindustrialisation, structural unemployment, environmental pollution, rural abandonment).
    • Requires comparative study of shifts in a named developed country alongside a named developing or emerging country.
    • Informal Employment in Megacities:
    • Root causes driving informal employment: uneven national economic development and high rates of rural-urban migration exceeding formal job creation.
    • Structural characteristics, opportunities, and risks (advantages such as immediate survival income, low barriers to entry, entrepreneurship; disadvantages such as lack of legal protection, hazardous working conditions, absence of healthcare or pensions, irregular wages, and lack of tax contribution) evaluated in a named megacity.
    • Theories on Population and Resource Dynamics:
    • Malthusian Theory (Thomas Malthus): Pessimistic model proposing that human population grows exponentially (1,2,4,8,16...1, 2, 4, 8, 16...) while food and resource production grows only arithmetically (1,2,3,4,5...1, 2, 3, 4, 5...), eventually triggering a Malthusian catastrophe through positive checks (war, disease, famine) and preventative checks (delayed marriage, moral restraint).
    • Boserupian Theory (Ester Boserup): Optimistic model proposing that "necessity is the mother of invention"; population pressure stimulates agricultural innovation, technological advancements, mechanisation, and intensification, enabling resource supply to keep pace with demand.
