Answers
A-Level Geography H1 Quiz - Map Graph Data Skills (Answer Key)
Section A: Data Interpretation and Description
- Definition: The arrangement or spread of a phenomenon across the Earth's surface. In urban geography, it refers to where specific land uses, populations, or services are located relative to one another (e.g., CBD vs. suburbs). [3]
- Limitation: Choropleth maps use predefined boundaries (e.g., administrative districts), which can hide internal variation (the "modifiable areal unit problem") or suggest a uniform distribution within a zone that is actually clustered. [4]
- Temporal Trend: An overall upward/increasing trend in temperature anomalies from 1880 to 2020, with a more rapid acceleration (steeper gradient) from approximately 1970 onwards. [4]
- Distinction: Positive correlation: Both variables increase together (e.g., as distance from CBD increases, house garden size increases). Negative correlation: As one variable increases, the other decreases (e.g., as distance from CBD increases, land value decreases). [4]
- Pattern: A positive correlation; as annual rainfall increases, the frequency of flash floods generally increases. (Students should mention the strength of the correlation—e.g., strong or weak—based on the hypothetical scatter). [5]
- Methods: Pie chart (shows proportions of a whole) or a stacked bar chart. [4]
- Explanation: A proportional symbol map uses the size of the symbol to represent the magnitude (total number) of cyclones at a specific point, whereas a dot map is better for showing density/distribution of individual events. Symbols allow for immediate visual comparison of the scale of impact between cities. [6]
Section B: Analysis and Application
- Account for: Urbanization replaces permeable soil with impermeable surfaces (concrete/tarmac). This reduces infiltration and increases surface runoff. Water reaches the river channel faster (short lag time) and in greater volumes (high peak discharge). [7]
- Process: Infiltration is the downward movement of water through soil. Concrete is impermeable, preventing water from entering the ground, whereas grassland has pore spaces and root systems that facilitate infiltration. [6]
- Distance Decay: The principle that the interaction between two points declines as the distance between them increases. For elderly residents with limited mobility, the further a clinic is from their home (as seen on the map), the less likely they are to access it, reducing their overall liveability. [7]
- Influence: High rainfall seasons (monsoons/wet seasons) increase the probability of flooding. Management activities (e.g., dredging drains, checking sea walls) must be completed before the peak rainfall months shown on the graph to ensure maximum efficiency. [7]
- Comparison: A line graph is superior for showing continuous change and trends over time (sea-level rise). A bar chart is better for comparing discrete values between specific years but fails to visualize the rate of change as effectively as a line. [6]
- Socio-economic reasons: Low-income groups are priced out of safe, serviced land. Steep slopes or floodplains are "marginal land" with low market value, making them the only accessible options for the urban poor. [8]
- Fear/Liveability: Bipolar surveys quantify subjective feelings. If the data shows strong negative scores for "safety" in a specific zone, it indicates that fear is a psychological barrier that limits the use of public spaces, thereby reducing the perceived liveability of that area. [7]
Section C: Evaluation and Synthesis
- Reliability: Low reliability. This is a "hasty generalization." One city is a small sample size and may have specific characteristics (e.g., poor drainage) that aren't universal. To be reliable, the student would need to compare multiple cities with different management strategies. [8]
- Usefulness: Highly useful. The land-use map shows where the people are (e.g., high-density residential) and the population map shows how many are there. Together, they reveal if crowding is due to a lack of residential space or an over-concentration of people in a specific land-use zone. [8]
- Validity: Low validity. A sample of 10 is not statistically representative of a whole neighborhood. It is prone to sampling bias (e.g., only interviewing friends or people on one street), meaning the conclusion cannot be generalized to the entire population. [8]
- Evaluation: Very useful. The photograph provides qualitative evidence of physical conditions (e.g., overcrowding, lack of paved roads), while the table provides quantitative evidence of service deficits (e.g., 20% access to clean water). Together, they provide a holistic view of both the environment and the systemic failures. [9]
- Extent: To a large extent, yes. A scatter graph is ideal for identifying correlations between two continuous numerical variables (GDP and Emissions). However, it does not show the temporal change of a country's progress, which would require a line graph. [8]
- Reliability: The timing may introduce bias. Tuesday morning may exclude working-age adults, meaning the data reflects the environment during a low-traffic period. Furthermore, if it rained on Monday, the soil might be pre-saturated, leading to artificially low infiltration rates that are not representative of "normal" conditions. [9]
