Using Figure 8 and your own knowledge, assess the view that fluvioglacial depositional processes dominate in the development of this landscape - AQA - A-Level Geography - Question 4 - 2018 - Paper 1

Introduction Fluvioglacial processes refer to the deposition by meltwater streams flowing from glaciers and their subsequent interactions with the landscape. In analyzing Figure 8 alongside external knowledge, it's evident that fluvioglacial processes play a significant role in shaping the Thompson Glacier's snout area.

Evidence for Fluvioglacial Processes The image depicts the glacier's snout where significant meltwater is evident. This meltwater stream visibly transports debris and sediment, indicating a high degree of erosion and deposition. This is consistent with the characteristics of fluvioglacial features such as eskers and outwash plains, which are results of meltwater activity.

Glacial Influences While fluvioglacial processes are prominent, glacial actions such as erosion via basal sliding and frost action cannot be overlooked. The glacier itself has advanced over time, eroding the landscape through mechanisms like abrasion. The historical data mentions substantial glacier movement, which further contributes to shaping the underlying landforms.

Interactions Between Processes There is a clear interaction between fluvioglacial and glacial processes; for instance, as the glacier retreats, the meltwater that flows from it transports sediments, creating unique landforms. Specific features visible in the image, like the various deposits at the glacier's base, display the layered nature of deposition that stems from both glacial and fluvioglacial actions.

Conclusion In conclusion, fluvioglacial depositional processes certainly dominate the landscape's development as seen in the figures and the analysis; however, it is crucial to recognize the integral role of glacial processes as well. The combination of these processes forms the complex dynamic of this glacial landscape.
