Question 6
Analyse the data shown in Figure 11a and Figure 11b. Note: Albedo PAR is a measure of the reflectivity of a surface. Darker surfaces absorb sunlight and warm up. L... show full transcript
Worked Solution & Example Answer:Analyse the data shown in Figure 11a and Figure 11b - AQA - A-Level Geography - Question 6 - 2019 - Paper 1
Step 1
Rainfall Trends
Answer
The data in Figure 11a demonstrates variability in rainfall over the period from 2009 to 2012. Notably, the wettest months appear to be from October to April, with substantial rainfall often exceeding 120 mm in certain months. The cumulative rainfall also shows significant increases, especially in December 2010 when it peaked at around 1800 mm.
Step 2
Soil Water Content and Albedo Relationship
Answer
Analyzing Figure 11b shows that the relationship between soil water content and albedo is complex. The soil water content rises following periods of higher rainfall indicated in Figure 11a, while albedo influences the soil heat and moisture retention. For instance, during the months of high soil water content, the albedo values appear to be lower, indicating darker surfaces which retain more moisture.
Step 3
Overall Analysis
Answer
In summary, both figures indicate the interconnectedness of rainfall patterns, soil moisture, and surface albedo in this woodlands savanna ecosystem. The dynamics suggest that increased rainfall correlates with lower albedo values, enhancing moisture levels in the soil. This pattern is particularly evident in the wetter months where soil water content spikes concurrent with maximum rainfall periods.
