Worked Solution & Example Answer:With reference to a multi-hazardous environment that you have studied, assess the view that the underlying cause(s) leading to the hazards is human activity rather than physical factors - AQA - A-Level Geography - Question 5 - 2018 - Paper 1
Step 1
Assessing the role of human activity in the causes of hazards
Answer
In this section, I will utilize the example of Los Angeles as a multi-hazardous environment. This area frequently faces hazards such as earthquakes and wildfires, which can be significantly influenced by human activity.
While the San Andreas Fault is a significant geological feature that contributes to seismic activity, the manner in which urban expansion and land management practices amplify this hazard is crucial.
Human activities such as the expansion of urban areas, often referred to as urban sprawl, increase the population's vulnerability to earthquakes, as many structures may not adhere to safe building regulations. Furthermore, the increase in infrastructure can lead to a greater number of casualties in the event of an earthquake.
Step 2
Evaluating the impact of physical factors
Answer
Despite the critical role of human activity, physical factors cannot be overlooked. For instance, the natural drought conditions in California contribute significantly to the intensity and frequency of wildfires.
The flammability of vegetation during droughts poses a natural hazard that is exacerbated by human-induced climate change. This interplay between natural and human factors illustrates that hazards do not arise solely from human activities, but they can be intensified by them.
Step 3
Concluding assessment
Answer
In conclusion, a nuanced understanding reveals that both human activity and physical factors play crucial roles in leading to hazards in Los Angeles. While human actions often amplify risks, it is the combination of both human and physical factors that culminate in hazardous environments. Therefore, the statement that human activity is the primary underlying cause is insufficient, as physical elements are equally influential.
