A-Level Geography H1 Quiz - Physical Geography (Answer Key)

Section A

1. Spatial Distribution: 1 mark for identifying concentration in tropical latitudes (5°-30° N/S). 1 mark for mentioning specific basins (North Atlantic/Pacific). 2 marks for using data/directional language (e.g., "concentrated in the western Pacific").
2. Temporal Distribution: 1 mark for identifying the overall trend (e.g., increase/stability). 1 mark for identifying specific time periods. 2 marks for referencing specific data points from the hypothetical Resource 1.
3. SST/Wind Shear: 2 marks for identifying SST $\ge 26.5^\circ\text{C}$ as the energy source. 2 marks for identifying low vertical wind shear as allowing the storm to maintain structure. 2 marks for linking these to the specific data in Resource 2.
4. Coriolis Force: 2 marks for defining it as the force resulting from Earth's rotation. 3 marks for explaining how it initiates the rotation/spiral of the cyclone (absent at the equator).
5. The Eye: 2 marks for characteristics (low pressure, calm winds, clear skies). 4 marks for explanation (descending air in the center inhibits cloud formation and creates a pressure gradient).
6. Infiltration: 2 marks for definition (downward movement of water into soil). 3 marks for factor (e.g., permeable soil/sand increases rate).
7. Topography/Lag Time: 3 marks for explaining that steep slopes increase surface runoff speed. 3 marks for linking this to a shortened lag time (peak discharge occurs sooner).
8. Evapotranspiration: 2 marks for definition (combined evaporation + transpiration). 3 marks for distinction (transpiration occurs via plant stomata).
9. Interception: 3 marks for explaining how canopy layers catch rain. 3 marks for linking this to delayed delivery of water to the soil, reducing immediate runoff.
10. Precipitation/Runoff: 3 marks for explaining that runoff occurs when precipitation exceeds infiltration capacity. 3 marks for linking intensity of rainfall to the volume of surface runoff.

Section B

11. Anthropogenic vs Natural: 4 marks for anthropogenic (GHG emissions, deforestation, industrialization). 4 marks for natural (volcanic eruptions, Milankovitch cycles, solar variability).
12. Urban vs Rural Floods: 4 marks for urban characteristics (impermeable surfaces/concrete). 4 marks for the resulting increase in surface runoff and decreased lag time.
13. Sea Level/Vulnerability: 4 marks for explaining thermal expansion/glacial melt. 4 marks for linking this to saltwater intrusion and higher storm surge levels in coastal cities.
14. Types of Floods: 4 marks for Flash Floods (intense rain, short duration). 4 marks for River Floods (prolonged rain, saturated basins).
15. Soft vs Hard Engineering: 4 marks for hard engineering (dams, levees - high cost, immediate effect). 4 marks for soft engineering (afforestation, zoning - sustainable, long-term). 2 marks for balanced evaluation.

Section C

16. Collective Effort:
    • Agree: Global nature of GHGs, need for shared funding, Paris Agreement.
    • Disagree: Role of individual national policies (e.g., carbon taxes), corporate net-zero goals, local community action.
    • Conclusion: Collective action is necessary for scale, but national implementation is where the actual reduction happens.
17. Alternative Energy:
    • Validity: Solar/Wind/Nuclear reduce carbon dependency.
    • Limitations: Intermittency, high initial cost, land use conflicts, need for energy storage.
    • Conclusion: Key component, but must be paired with efficiency and carbon capture.
18. Climatic Factors vs Basin:
    • Climate: Rainfall intensity and temperature drive the system.
    • Other Factors: Geology (permeability), Topography (slope), Vegetation (interception).
    • Conclusion: Climate provides the "input," but basin characteristics determine the "process" and "output."
19. Adaptation vs Mitigation:
    • Adaptation: Dealing with current impacts (sea walls, drought-resistant crops). More immediate.
    • Mitigation: Addressing the root cause (reducing emissions). More sustainable long-term.
    • Conclusion: Both are required; adaptation is a survival necessity, mitigation is a systemic solution.
20. International Agreements:
    • Successes: Global consensus, framework for reporting, awareness.
    • Failures: Lack of enforcement mechanisms, "free-rider" problem, insufficient targets to meet $1.5^\circ\text{C}$.
    • Conclusion: Useful as a diplomatic catalyst, but limited by national sovereignty.
