Worked Solution & Example Answer:Figure 7a shows the distribution, size and type of selected Himalayan glaciers - AQA - A-Level Geography - Question 4 - 2022 - Paper 1
Step 1
Description of Figure 7a
Answer
Figure 7a presents the distribution, size, and type of selected Himalayan glaciers. The glaciers are predominantly situated in the northern section, spanning east to west. Some noted variations include that the southern glaciers exhibit a tendency toward greater sizes, with different types categorized primarily by their morphological characteristics.
Step 2
Observations from Figure 7b
Answer
Figure 7b illustrates the mass balance changes for the same glaciers from 2000 to 2016. Overall, a negative mass balance is observed for most glaciers, suggesting they are losing mass over time. Specifically, some glaciers are noted to have a consistent negative trend, which indicates climate factors, such as temperature increases and precipitation changes, impacting glacier health.
Step 3
Comparative Analysis
Answer
The connection between the data in Figures 7a and 7b can be highlighted by noting that larger glaciers, particularly those in the southern regions, show greater fluctuations in mass balance compared to smaller ones. This indicates that while size plays a role, external climatic factors may also significantly influence glacier dynamics.
Step 4
Summary of Anomalies
Answer
Anomalies are evident, such as the particular glacier in the south experiencing a less negative mass balance compared to the others. This anomaly might be due to localized climatic conditions or differences in glacier geography. Overall, the data suggests continued monitoring is essential given the evident trends of mass loss.
