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 the landscape of Striding Edge. The primary erosion processes include weathering, ice movement, and glacial activity.

1. Weathering Processes: Physical weathering, caused by freeze-thaw cycles, contributes to the breakdown of rock in the mountainous environment. When water enters fractures in the rock and freezes, it expands, causing the rock to crack further and eventually break apart.

2. Ice Movement: The movement of glaciers during periods of glaciation has significantly influenced Striding Edge's formation. As glaciers advance and retreat, they can carve out deep valleys and create sharp ridges and arêtes.

3. Glacial Erosion: The process of abrasion occurs as the glacier moves over the bedrock, scraping away the surface material. This results in features like striations on the rock and contributes to the steepness of the edges.

4. Landform Characteristics: The steep, jagged nature of Striding Edge is a direct result of these erosional processes. The erosion-resistant features seen in the landscape are the harder rock types that remain after softer materials have been worn away, helping shape the characteristic profile of the area.

5. Impact of Weather: Additionally, ongoing weathering occurs from rain and wind, which can further alter the surface of Striding Edge. For example, the action of rain can lead to chemical weathering and the eventual breakdown of minerals within the rock.

In summary, the interaction of these erosive forces continues to shape Striding Edge, highlighting the dynamic nature of glacial landscapes.
