Study Notes
Mining Methods
- Subsurface mining: Miners dig shafts deep into the earth to reach buried ore deposits.
- Open-pit mining: Large areas of soil are removed to access ore near the surface.
- Hydraulic fracturing (Fracking): High-pressure water, chemicals, and sand are used to force oil and gas out of rock formations.
- Placer mining: Water is used to separate minerals from sediment.
Environmental Impacts
- Mountaintop removal mining: Leads to widespread destruction of ecosystems, water contamination, and air pollution.
- Fracking: Potential environmental impacts include groundwater contamination, small earthquakes, and increased methane emissions.
Fossil Fuel Extraction
- Natural gas: Extracted by drilling wells into underground reservoirs.
- Coal: Extracted through various methods, including surface mining, subsurface mining, and mountaintop removal.
- Oil shale: A rock formation containing oil that can be extracted through mining and processing.
- Tar sands: Sand deposits containing oil that can be extracted through mining and processing.
