Worked Solution & Example Answer:Figure 1 shows changes in the terrestrial water system in response to human activity and climate change between 2012 and 2016 - AQA - A-Level Geography - Question 1 - 2022 - Paper 1
Step 1
Changes from 2012 to 2016
Answer
The changes observed between 2012 and 2016 in the terrestrial water system are highly variable across different regions. Some areas show significant decreases in terrestrial water, while others exhibit increases. For instance, regions like Greenland and Antarctica have experienced notable ice sheet loss and probable climate change effects. In contrast, places like Southeast Asia indicate mixed trends, with certain parts experiencing both water depletion and accumulation.
Step 2
Impact on Specific Regions
Answer
It's crucial to analyze particular areas. In regions around the Arctic, there is evidence of enhanced melting, contributing to less terrestrial water availability. On the other hand, areas such as parts of Siberia have shown unexpected increases in water levels, possibly due to climatic shifts. Consequently, understanding these regional differences is essential to grasp the overall changes in the terrestrial water system.
Step 3
Human Activity Considerations
Answer
Human activities such as deforestation, agriculture, and urbanization have also contributed to the observed changes. For instance, in Southeast Asia, large-scale agricultural practices have altered natural water flows, leading to reduced water levels. Conversely, improved water management practices in certain areas could potentially enhance water availability.
