Which statement best evaluates the significance of modern natural gas extraction on the physical environment?(1 point)
Responses
A. Hydraulic fracturing does not contribute to the modification of the atmosphere by releasing greenhouse gases.
B. Hydraulic fracturing removes water resources from natural sources.
C. Wastewater produced from hydraulic fracturing is clean and can be released into Earth’s waterways.
D. Hydraulic fracturing does not lead to habitat fragmentation.
B. Hydraulic fracturing removes water resources from natural sources.
The correct answer is:
C. Modern roads modify the physical environment by leading to suburban sprawl.
To evaluate the impact of modern roads on the physical environment, we need to carefully analyze the options and select the statement that best aligns with our understanding of road infrastructure and its effects.
Option A suggests that modern road design alongside rivers and streams allows water to flow naturally. This statement is partly correct, as modern road design often includes bridge structures that allow water to flow beneath the road, reducing the risk of flooding. However, it does not provide a comprehensive evaluation of the overall impact of modern roads on the physical environment.
Option B states that modern roads decrease habitat fragmentation. This statement is not entirely accurate. While it is true that some efforts are made to reduce the impact of roads on wildlife habitats, such as wildlife corridors or tunnels, the construction and expansion of roads often lead to significant habitat fragmentation. Therefore, option B does not provide a comprehensive evaluation of the impact.
Option C suggests that modern roads modify the physical environment by leading to suburban sprawl. This option acknowledges an important aspect of modern road infrastructure. Roads often act as catalysts for urban development and have contributed to the expansion of cities and suburban areas. As a result, natural landscapes are transformed, leading to the loss of biodiversity and altering the physical environment. Thus, option C can be seen as a more accurate evaluation.
Option D states that modern roads are designed to avoid harsh conditions, such as deserts. While it is true that roads are generally built to withstand and navigate challenging terrain, such as rocky or mountainous regions, this statement does not encompass the overall impact of modern roads on the physical environment.
Based on the evaluation above, the statement that best evaluates the impact of modern roads on the physical environment is option C: "Modern roads modify the physical environment by leading to suburban sprawl."
