Using Figure 8 and your own knowledge, assess the role of erosion in the development of this landscape feature - AQA - A-Level Geography - Question 4 - 2022 - Paper 1

Erosion plays a significant role in shaping Striding Edge, primarily through various geomorphological processes. The interaction of weathering, ice movement, and physical erosion have contributed to the development of this distinctive landscape.

1. Weathering Processes: The rock face experiences physical weathering due to temperature fluctuations, causing expansion and contraction. This process leads to the breakdown of rock materials into smaller particles.

2. Glacial Erosion: During glacial periods, ice movement would have played a vital role. As glaciers flow, they exert immense pressure on the surrounding landscape. This pressure, combined with the abrasive action of embedded rocks in the ice, leads to significant erosion, carving out features like Striding Edge.

3. Arêtes Formation: Striding Edge is a classic example of an arête, which forms when two glaciers erode adjacent valleys, creating a sharp ridge. The distinctiveness of the landscape can be attributed to the continuous erosion on either side by glacial activity.

4. Post-glacial Processes: After glaciation, the landscape is further shaped by processes such as mass wasting and weathering. Rock falls, particularly from the steep sides of the ridge where weakened rock has left it vulnerable, further modify the terrain.

5. Role of Resistant Rock: The presence of more resistant rock types also influences erosion patterns. The harder rock layers remain while softer materials are eroded away, contributing to the height and steepness of Striding Edge.

By analyzing these processes, it becomes evident that erosion not only initiated the formation of Striding Edge but continues to shape its landscape through ongoing geological interactions.
