Worked Solution & Example Answer:Using Figure 8 and your own knowledge, assess the view that fluvialglacial depositional processes dominate in the development of this landscape - AQA - A-Level Geography - Question 4 - 2018 - Paper 1
Step 1
Assess the evidence from Figure 8
Answer
In Figure 8, the image clearly shows the dynamics at the snout of the glacier. The presence of meltwater flowing from the glacier indicates active fluvial processes. The way the water interacts with the glacial debris suggests that erosion and transportation by meltwater play significant roles in shaping the landscape. The accumulation of sediment around the snout further supports the view that fluvial processes are at work here.
Step 2
Discuss glacial processes
Answer
Glacial processes, such as weathering, frost action, and internal deformation, also significantly influence the landscape. In the context of the Thompson Glacier, ablation (the loss of ice) and accumulation (the gain of ice) occur regularly, affecting the morphology of the area. Thus, while fluvial processes are crucial, the glacial context cannot be ignored.
Step 3
Evaluate the interaction of fluvial and glacial processes
Answer
It is essential to recognize that fluvial and glacial processes often interact. The meltwater from the glacier assists in transporting glacial till, which contributes to the landforms seen in the area, such as outwash plains and eskers. Therefore, both processes are important in understanding the overall development of the landscape.
