Worked Solution & Example Answer:Analyse the data shown in Figure 3a and Figure 3b - AQA - A-Level Geography - Question 2 - 2021 - Paper 1
Step 1
Analysis of Figure 3a
Answer
Figure 3a indicates significant rainfall across Saudi Arabia during the wet season from November to April. The southern regions, such as Jeddah and further south, receive the highest rainfall, ranging from 200 mm to over 400 mm. In contrast, the northern parts generally receive less rainfall, often below 100 mm. This distribution highlights how geographical positioning influences rainfall, with mountainous areas typically gathering more precipitation.
Step 2
Analysis of Figure 3b
Answer
Figure 3b illustrates the average total rainfall during the dry season from June to September. The data shows a marked decrease in rainfall across most of the regions, with many stations reporting less than 20 mm. Notably, regions such as Riyadh and the eastern parts experience nominal rainfall, often failing to exceed 10 mm. This stark contrast demonstrates the seasonal variability in Saudi Arabia's climate, where the wet season vastly outperforms the dry season in precipitation.
Step 3
Comparison Between the Two Figures
Answer
Comparing Figures 3a and 3b reveals a critical shift in rainfall patterns according to the seasons. There is a substantial difference in total rainfall: while the wet season records significant precipitation, the dry season sees a severe reduction. The greatest difference can be observed in regions like Rub’ al Khali, where water availability drops dramatically, showcasing how rainfall is not only seasonal but also location-dependent.
