APES Mining and Extraction Impacts
36 flashcards covering APES Mining and Extraction Impacts for the AP-ENVIRONMENTAL-SCIENCE Unit 5 section.
Mining and extraction impacts encompass the environmental, social, and economic consequences of resource extraction activities. This topic is defined within the AP Environmental Science curriculum, particularly in Unit 5, which focuses on land and water use, including the effects of mining on ecosystems and communities. Key regulations and guidelines, such as the National Environmental Policy Act (NEPA), provide a framework for understanding the legal implications of mining practices.
In practice exams and competency assessments, questions about mining and extraction impacts often require students to analyze case studies or interpret data related to environmental degradation, habitat destruction, and resource depletion. A common pitfall is overlooking the long-term ecological effects, such as soil erosion and water contamination, which can lead to incorrect answers when assessing the sustainability of mining practices. It’s crucial to consider both immediate and lasting impacts when evaluating mining operations. One real-world tip is to always assess the cumulative impact of multiple mining projects in a region, as this can significantly alter environmental conditions.

When is it necessary to conduct an Environmental Impact Statement (EIS) for mining projects?
An Environmental Impact Statement (EIS) is necessary for mining projects that may significantly affect the environment, as mandated by the National Environmental Policy Act (NEPA) (College Board AP CED).
- 13
What is the significance of the Resource Conservation and Recovery Act (RCRA) in mining?
The Resource Conservation and Recovery Act (RCRA) regulates the management of hazardous waste from mining operations, ensuring that waste is handled in a manner that protects human health and the environment (College Board AP CED).
- 14
How does mining affect biodiversity?
Mining affects biodiversity by destroying habitats, which can lead to species extinction and a decrease in genetic diversity within ecosystems due to habitat fragmentation (College Board AP CED).
- 15
What is the purpose of the Mine Safety and Health Administration (MSHA)?
The Mine Safety and Health Administration (MSHA) aims to protect the safety and health of miners by enforcing regulations and conducting inspections at mining operations (College Board AP CED).
- 16
What are the long-term consequences of mining on landscapes?
Long-term consequences of mining on landscapes include altered topography, persistent pollution, and changes in hydrology, which can hinder ecosystem recovery and land usability (College Board AP CED).
- 17
How does mining contribute to climate change?
Mining contributes to climate change through greenhouse gas emissions from machinery, transportation, and the energy used in extraction processes, as well as land-use changes that affect carbon storage (College Board AP CED).
- 18
What is the impact of mining on groundwater?
Mining can impact groundwater by altering aquifer recharge rates, contaminating water supplies with pollutants, and changing the flow patterns of underground water (College Board AP CED).
- 19
What is a common method for assessing the environmental impacts of mining?
A common method for assessing the environmental impacts of mining is conducting a life cycle assessment (LCA), which evaluates the environmental effects of a mining operation from extraction to closure (College Board AP CED).
