Using Figure 4 and your own knowledge, assess the view that low precipitation is the most important factor leading to the development of this landscape - AQA - A-Level Geography - Question 2 - 2020 - Paper 1

Low precipitation is indeed a significant factor in the formation of desert pavements as seen in Figure 4. In such arid environments, limited rainfall leads to minimal vegetation cover, resulting in soil exposure and increased erosion.

Desert pavements form as finer particles are washed away by rainwater, leaving behind larger stones. The lack of precipitation decreases the soil's ability to retain moisture, further inhibiting plant growth, which would otherwise help to stabilize the soil. This is evidenced by the barren and rocky landscape visible in the figure.

Moreover, the harsh climatic conditions driven by low moisture levels lead to intense weathering processes like thermal expansion and contraction, contributing to landscape development. Yet, it’s crucial to acknowledge that while low precipitation is a core driver, other factors such as wind erosion and surface characteristics also play significant roles.

Wind activity can transport sand and finer materials, eroding surface features and influencing the overall landscape morphology. Additionally, the geological composition of the area determines how resistant the surface materials are to such processes.

In conclusion, while low precipitation substantially contributes to landscape development in Naein, it should be viewed in conjunction with other geological and environmental elements to fully understand this unique desert landscape.
