A-Level Geography H2 Quiz - Map Graph Data Skills

Name: __________________________
Class: __________________________
Date: __________________________
Score: ________ / 85

Duration: 90 Minutes
Total Marks: 85
Instructions: Answer all questions. Use the provided resources where applicable. Show all workings for calculations.

Section A: Cartographic & Climate Classification (Questions 1-7)

Focus: Map interpretation and Köppen-Geiger systems.

Resource 1: A climograph of City X showing a mean temperature of 27°C throughout the year and monthly precipitation values: Jan (250mm), Feb (210mm), Mar (180mm), Apr (120mm), May (100mm), Jun (80mm), Jul (70mm), Aug (90mm), Sep (150mm), Oct (220mm), Nov (280mm), Dec (300mm).

Identify the climatic zone of City X according to the Köppen-Geiger climate classification system. Support your answer with data from Resource 1. [4]
Based on Resource 1, describe the seasonal precipitation pattern of City X. [3]
Explain how the temperature data in Resource 1 justifies the "A" (Tropical) classification. [3]
If the precipitation in July were 40mm instead of 70mm, how would this potentially change the Köppen-Geiger classification? Explain your reasoning. [4]
Name the mapping technique used to represent a three-dimensional variable (e.g., elevation) on a two-dimensional map. [2]
Explain one limitation of using a choropleth map to represent population density across a large region. [4]
Distinguish between a proportional symbol map and an isarithmic map. [4]

Section B: Data Interpretation & Comparison (Questions 8-14)

Focus: Comparative analysis of scores and indices.

Resource 2: Table showing Sustainability Index Scores (0-100) for four cities.

City	Environmental Quality	Social Equity	Economic Viability
City A	72	45	88
City B	55	62	50
City C	81	38	74
City D	40	78	42

Compare the scores for the four cities in Resource 2 in terms of Environmental Quality. [5]
Which city demonstrates the greatest disparity between its highest and lowest scoring dimensions? Show your working. [4]
Describe the relationship between Social Equity and Economic Viability across the four cities. [4]
Using the data in Resource 2, identify which city is most likely to be a "developed" city and justify your choice. [5]
Explain why a city might score high in Economic Viability but low in Social Equity. [5]
Suggest one way the data in Resource 2 could be presented more effectively to show the overall sustainability "profile" of each city. [3]
If a fifth city, City E, was added with scores (60, 60, 60), how would it compare to City B? [4]

Section C: Synthesis & Technical Analysis (Questions 15-20)

Focus: Integration of data and geographical processes.

Resource 3: A series of photographs showing a limestone landscape with deep sinkholes and an underground river system.

Identify the specific type of landscape shown in Resource 3. [2]
Explain the chemical process that leads to the formation of the features seen in Resource 3. [7]
Describe how the presence of joints and bedding planes in the rock influences the spatial distribution of the features in Resource 3. [5]
Explain the role of rainfall and temperature in accelerating the processes shown in Resource 3. [6]
Using your knowledge of data skills, explain how a GIS (Geographic Information System) could be used to map the risk of sinkhole collapse in this region. [7]
Evaluate the reliability of using only photographic evidence (like Resource 3) to determine the rate of landscape evolution. [8]

Answer Key - A-Level Geography H2 Quiz (Map Graph Data Skills)

Section A

Af (Tropical Rainforest). Evidence: Mean temperature is constant at 27°C (>18°C). All months have precipitation >60mm (lowest is 70mm in July). [4]
Bimodal/Seasonal. High precipitation in winter (Dec-Jan, >250mm) and summer (Oct-Nov), with a distinct dip/dryer period in mid-year (June-August), though still humid. [3]
Temperature Stability. The mean temperature is 27°C throughout the year, which is well above the 18°C threshold for the Tropical (A) group in the Köppen-Geiger system. [3]
Change to Am (Tropical Monsoon) or Aw (Tropical Savanna). If July drops to 40mm, it falls below the 60mm threshold for Af. Depending on the total annual rainfall and the length of the dry season, it would shift to Am or Aw. [4]
Contour lines / Hypsometric tinting. [2]
Modifiable Areal Unit Problem (MAUP) / Ecological Fallacy. Choropleth maps aggregate data into administrative boundaries, masking internal variations (e.g., a high-density slum next to a low-density park in the same zone). [4]
Proportional Symbol: Uses symbols of varying sizes to show absolute quantities (e.g., circle size for city population). Isarithmic: Uses lines to connect points of equal value (e.g., isohyets for rainfall). [4]

Section B

Comparison: City C has the highest Environmental Quality (81), followed by City A (72). City B is moderate (55), while City D has the lowest score (40). [5]
City D. Calculation: $78 (Social) - 40 (Env) = 38$ or $78 - 42 = 36$ . City A: $88-45=43$ . Correction: City A has the greatest disparity (43 points). [4]
Inverse/Negative Correlation. Generally, cities with higher Economic Viability (City A, City C) tend to have lower Social Equity scores, whereas City D has high Social Equity but low Economic Viability. [4]
City A or C. Justification: High scores in Economic Viability (88/74) and relatively strong Environmental Quality suggest the infrastructure and wealth typical of developed urban centers. [5]
Economic Growth vs. Distribution. Rapid industrialization or financial sector growth (high economic score) often leads to gentrification, wealth gaps, and marginalization of low-income groups (low social equity). [5]
Radar Chart (Spider Diagram). This would allow for a visual comparison of the "shape" of sustainability across the three dimensions for each city. [3]
Comparison: City E is more balanced/consistent (60 across all). City B is slightly more socially equitable (62) but lower in environmental quality (55) and economic viability (50) compared to E. [4]

Section C

Karst Landscape. [2]
Carbonation Process. Rainwater absorbs $\text{CO}_2$ to form weak carbonic acid. This acid reacts with calcium carbonate ( $\text{CaCO}_3$ ) in limestone, dissolving the rock into soluble calcium bicarbonate, which is carried away in solution. [7]
Structural Control. Joints and bedding planes provide pathways for water to infiltrate. Dissolution is concentrated along these weaknesses, leading to vertical shafts (sinkholes) and horizontal conduits (cave systems). [5]
Climate Acceleration. High rainfall provides the volume of water needed for dissolution and transport. High temperatures increase the rate of chemical reactions (Arrhenius equation), speeding up the carbonation process. [6]
GIS Application. Layering: 1. Geological map (limestone extent), 2. Hydrological map (water table/drainage), 3. Historical collapse data. Overlay analysis identifies "hotspots" where high solubility intersects with high water flow. [7]
Evaluation. Low reliability for rate. Photographs are "snapshots" in time. They show the result of processes (morphology) but not the speed (chronology). To determine rate, one would need geomorphological dating (e.g., uranium-thorium) or long-term monitoring data. [8]
