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 Variability
Answer
The data reveals substantial variability in rainfall across the examined years. For instance, December on average records the highest values with over 120 mm, while it notably decreases in the dry seasons. In comparing the yearly data, 2011 shows significant cumulative rainfall, reaching approximately 400 mm from February onwards.
Step 2
Albedo and Soil Water Content Relationship
Answer
Figure 11b demonstrates a clear inverse relationship between albedo and soil water content. Albedo is observed to increase during dry months when soil water content is low. Conversely, when soil moisture levels are high, albedo shows a marked decrease, indicating the absorptive capacity of wet soil surfaces.
