Answer :
Final answer:
This answer outlines the positive and negative aspects of subsurface and surface mining, explains how placer deposits form, lists potential environmental impacts of mining, and describes how state governments regulate mining activities. Understanding these factors is crucial for evaluating the implications of mining operations. The discussion highlights critical considerations for environmental sustainability and economic benefits of mining.
Explanation:
1. Positive and Negative Aspects of Subsurface Mining
Subsurface mining is the extraction of minerals from beneath the earth's surface. The positive aspects include:
- Less surface disruption: It minimizes the impact on the landscape compared to surface mining.
- Access to deeper minerals: It allows for the mining of mineral deposits that are not feasible to reach by surface methods.
However, the negative aspects are significant:
- Health risks: Miners are exposed to hazardous conditions, including cave-ins and harmful airborne particles.
- Contamination of groundwater: Leaking chemicals can pollute water sources, affecting ecosystems and human populations.
2. Positive and Negative Aspects of Surface Mining
Surface mining involves removing the earth's surface to access mineral deposits. The benefits include:
- Cost-effective: It is generally cheaper and safer than subsurface mining.
- Immediate access: Minerals can be quickly accessed and extracted.
On the negative side:
- Environmental degradation: It causes extensive alteration to the land surface, impacting habitats and ecosystems.
- Pollution: Runoff can lead to pollution of nearby water bodies.
3. How Placer Deposits Form
Placer deposits occur when minerals are concentrated by the action of water, typically through erosion and sedimentation. Heavy minerals like gold tend to settle in the bed of rivers or streams after lighter materials are washed away. This can lead to economically viable concentrations of minerals.
4. Seven Potential Environmental Impacts of Mining
- Habitat destruction
- Soil erosion
- Water pollution
- Air pollution
- Changes in land use.
- Loss of biodiversity
- Displacement of local communities
5. Ways State Governments Regulate Mining
State governments regulate mining through various mechanisms:
- Permitting processes: Companies must obtain permits before beginning operations, ensuring compliance with environmental standards.
- Environmental assessments: Requirements for environmental impact assessments help to evaluate the potential impacts of proposed mining activities and determine necessary mitigation measures.
