Worked Solution & Example Answer:Analyse the data shown in Figure 9 and Figure 10 - AQA - A-Level Geography - Question 5 - 2018 - Paper 1
Step 1
Figure 9 Analysis
Answer
Figure 9 suggests a correlation between the number of earthquakes and the vertical deformation in the caldera over the years. Notably, the large earthquake peak in 1985 aligns with substantial vertical deformation measured at about 30 cm. This trend indicates that heightened seismic activity appears to coincide with notable vertical shifts in the caldera.
Step 2
Figure 10 Analysis
Answer
Figure 10 presents a topographical view of Yellowstone National Park showing areas of subsidence and uplift. The significant deformation in regions labeled SC and ML reflects ongoing geological processes. Areas of uplift suggest ongoing volcanic activity, reinforcing the observations made in Figure 9 regarding earthquakes and vertical motion.
Step 3
Connection between Figures 9 and 10
Answer
Both figures collectively illustrate an active geological environment in Yellowstone. The correlation between the earthquake data in Figure 9 and the deformation patterns in Figure 10 underscores the interconnectedness of seismic activity with geological shifts in the caldera. This suggests that both earthquake occurrences and ground deformations are likely influenced by the underlying magmatic processes.
