O Level Geography Map Graph Data Skills Quiz

Answer Key - O-Level Geography Quiz (Map Graph Data Skills)

1. Anemometer (1 mark)

2. Thermometer / Barometer / Hygrometer (1 mark)

3. Line graph / Scatter plot with line of best fit (1 mark for graph type, 1 mark for justification: allows comparison of temperature change across a continuous variable like altitude). (2 marks)

4. Line graphs are designed for time-series data (1). They allow the viewer to easily identify trends, fluctuations, and the rate of change over a continuous period (1). Bar charts are better for discrete categories, not continuous time (1). (3 marks)

5. It suggests a plate boundary (1). Specifically, a convergent boundary or a divergent ridge (1). The linear arrangement indicates the edge of a tectonic plate where activity is concentrated (1). (3 marks)

6. Overall increase from 1.2m in 2018 to 1.4m in 2022 (1). However, there was a sharp decline to 0.3m in 2020 (1), followed by a steady recovery in 2021 and 2022 (1). (3 marks)

7. Working: $[(1.5 - 0.3) / 1.5] \times 100$ (1). Calculation: $1.2 / 1.5 = 0.8$ (1). Answer: 80% decrease (1). (3 marks)

8. Global pandemic (COVID-19) leading to travel restrictions/border closures (2). (2 marks)

9. Assign numerical weights to categories (e.g., +2, +1, -1, -2) (1). Multiply the frequency of each response by its weight (1). Sum the results to find the total positive and negative scores (1). (3 marks)

10. Working: $(5 \times 2) + (10 \times 1) + (12 \times -1) + (8 \times -2)$ (1). Calculation: $10 + 10 - 12 - 16 = -8$ (1). Answer: -8 (1). (3 marks)

11. Negative perception (1). The total weighted score is negative (-8), indicating that dissatisfaction outweighs satisfaction (1). (2 marks)

12. A comparative bar chart (1) or a radar chart (1) to show the scores of different amenities side-by-side. (2 marks)

13. Earthquakes are not randomly distributed (1). They are concentrated along plate boundaries (1), such as the Pacific Ring of Fire and the Mid-Atlantic Ridge (1). (3 marks)

14. The Ring of Fire is a zone of intense tectonic activity (1). It consists of many subduction zones where oceanic plates sink beneath continental plates (1). This process creates immense friction and pressure, leading to frequent and powerful earthquakes and volcanic eruptions (2). (4 marks)

15. Not reliable (1). The sample size of 2 people per location is too small to be representative of the population (1). Individual biases or unique experiences of those two people will disproportionately affect the result (1). This leads to a lack of statistical validity (1). (4 marks)

16. Increase sample size (e.g., 20-30 people per site) to reduce the impact of outliers (2). Use stratified sampling to ensure different age groups or demographics are represented (2). (4 marks)

17. Clean water reduces the transmission of waterborne diseases like cholera and dysentery (1). This leads to lower infant and child mortality rates (1). Improved health allows for better nutrition and overall wellbeing (1), which directly increases the average life expectancy of the population (1). (4 marks)

18. Increasing $\text{CO}_2$ levels mean more greenhouse gases are present in the atmosphere (1). These gases absorb long-wave infrared radiation emitted by the Earth's surface (1). Instead of escaping into space, the heat is re-radiated back to the surface (1), leading to a rise in global average temperatures (1). (4 marks)

19. Disagree (1). A single source may be biased or contain errors (1). Using multiple sources (triangulation) allows a geographer to cross-verify data and identify patterns more accurately (1). This increases the reliability and validity of the conclusion (1). (4 marks)

20. Maps provide visual evidence of the extent of land added (1). They allow for the analysis of spatial distribution and proximity to key economic hubs (1). However, maps alone do not show the "success" in terms of economic ROI or environmental cost (1). Therefore, they must be paired with quantitative economic data to be fully evaluative (1). (4 marks)
