|---|---|---|---|---|---|
| Minerals | Naturally occurring material on/in the Earth's surface with an internal crystalline structure.
🗑
|
||||
| Metallic Minerals | Examples include Al, Fe (iron), Au (gold), Ag (silver)
🗑
|
||||
| Non-Metallic Minerals | Examples include sand, gravel
🗑
|
||||
| Single Element Mineral | Au (gold), Ag (silver)
🗑
|
||||
| Several Elements Minerals | Salt (NaCl), Quartz (silicon dioxide) SiO2
🗑
|
||||
| Rock | Made up of one or more minerals that is part of the Earth's crust
🗑
|
||||
| Single Mineral Rock Composite | Example: Limestone (calcium carbonate)- CaCO3
🗑
|
||||
| Several Mineral Rock Composite | Example: Granite (mixture of mica, feldspar, and quartz)
🗑
|
||||
| Ore | Rock that contains metal
🗑
|
||||
| Rock Formation | 1. Igneous Rock
2. Sedimentary Rock
3. Metamorphic Rock
🗑
|
||||
| Igneous Rock | Either on/inside Earth's crust formed from magma/lava
Ex: Granite
🗑
|
||||
| Sedimentary Rock | Rock that forms in layers from dead plants and animals over time
Ex. Sandstone, limestone, shale
🗑
|
||||
| Metamorphic Rock | Pre-existing rock that is reshaped internally from high temperature and pressures.
Ex. Slate, Marble
🗑
|
||||
| Rock Cycle | Is the slowest of all cycles and considered the most important:
1. Concentrates non-renewable resources. (Releases minerals to food chain)
2. Continuance of life on planet.
🗑
|
||||
| Get Coal: | Mining of Mineral Deposits
🗑
|
||||
| Surface Mining | 1. Open-Pit: Big Hole
2. Area Strip Mining: Flat Surface
3. Contour Strip Mining- Leaves some vegetation, occurs on hills/mountain sides
🗑
|
||||
| Sub-Surface Mining | 1. More environmentally sound.
2. Uses about 10% less land.
3. Generates less mining waste.
🗑
|
||||
| Environmental Effects of Mining | 1. Scarring/destruction of land
2. Potential for land collapse (subsidence)
3. Pollution of land/water
4. Toxic mining waste
5. Toxic air emissions
6. Tailings
🗑
|
||||
| Subsidence | Potential for land collapse
🗑
|
||||
| 75% | ...of all US solid waste is generated by mining.
🗑
|
||||
| Sulfuric Acid | FeS (Iron Sulfide) when digging reacts with aerobic bacteria + H2O = H2SO4- Runs off into stream
🗑
|
||||
| Tailings | Metallic ore waste.
🗑
