- 1Using the graph, what is the general trend? Is there anything concerning?The number and years are very low meaning we need to cut down our use of these minerals. The minerals will soon become scarce and costly
- 2If nothing else changes, but we recycle more what will happen to these numbers?It will help the numbers increase, especially in economically recoverable areas. Because the more we recycle the less we have to mine.
- 3If we have increased consumption what will happen to the graph?Prices would increase, and we will run out sooner
- 4Based on this graph would you say our mineral use is sustainable or unsustainable?Unsustainable
- 5Mineral extraction by removing 100 vertical meters from a hill or mountaintop is called what?Mountaintop removal mining
- 6what type of mining is it when you excavate a giant whole in a landscape?Open pit mining
- 7What is the type of mining where you sift through sand and silt in river beds for minerals using a sluice for running water?Plaster mining
- 8What type of mining involves tunneling deep underground to extract the metals?Subsurface mining
- 9Surface layers are removed to expose and extract horizontal mineral deposits?Strip mining
- 10What is the term for restoring mined areas to pre-mined conditions?Reclamation
- 11A naturally occurring solid element with a distinct composition and a solid/crystal texture?Mineral
- 12Which layer of the earth are minerals found in?Lithosphere
- 13If a mineral is opaque, malleable, lustrous, and can conduct heat and electricity what is it?Metal
- 14What is the term for heating metal beyond its melting point and combining the metal with carbon?Smelting
- 15Where is most coltan and ore mined, and where does it end up?It is primarily mined in the Congo and ends up in North America, Western Europe, Japan, Asia
- 16What was the focus of a 2001 inquiry?Environmental and social justice for the Congo
- 17Tantalum comes from coltan mined in africa what is this metal used for?Electronics, cell phones, cameras etc. (basically electronics) Communication devices. When you have a wire or layer of tantalum it oxidizes and is like a self insulation wire.
- 18What do we mine using Subsurface mining?Coal, Diamonds, Phosphate, Gold
- 19Heavy damage and water pollution are caused by what mining?Mountaintop removal mining
- 20What are the problems with coltan mining in the congo and appalachians?Environmental damage and social justice issues, not much profit for most
- 21We talked about the us general mining act of 1872, it encouraged domestic mining, but what problems did it cause?It gives away resources and public land basically for free
- 22Given our low supplies of rare metals, we can extend the life time by doing what?Recycling
- 23Which layer of the earth surrounds the core as a thick layer of rock?Mantle
- 24How much energy is saved by recycling aluminum versus mining it?95%
- 25Where are the newest sources of potentially recycling scarce and toxic metals coming from?Ewaste
- 26What type of water pollution is produced by mines, like coal and copper?Acid drainage
- 27What kind of things do we mine that are non-metals, not including coal?Gravel, sand, phosphate, gems
- 28There is a new process for removing metals from acid sulfate pollution, What is it?It is called sulfate producing bacteria. It causes precipitation of heavy metals (look at notes)
- 29Which part of the earth includes the upper most part of the mantel and the crust?Lithosphere
- 30What causes the movement of tectonic plates?Convection Currents in the rock
- 31What type of rock is formed by sedimented materials being pressed together?Sedimentary Rock
- 32What type of rock rock is formed magma?Igneous
- 33Where are earthquakes most likely to occur?Tectonic plate boundaries (mainly transform boundaries)
- 34Where do volcanoes typically occur?Convergent Boundaries, (Subduction Zones and Rift Valleys)
- 35What does the Pacific Ring of fire?It is a zone with lots of earthquakes, and Volcanoes (active)
- 36What causes Tsunamis?Earthquakes, Seawater Volcanoes, Landslides
- 37Discuss elements of sustainable mineral management.Recycling, finding a replacement for scarce components such as tantalum, find new extraction technologies that are efficient.
- 38Discuss the major environmental impacts of mining operations.There is a huge landscape alteration, pollution of water and air, clogging of streams, loss of biodiversity, acid drainage, water sulfate problems, lots of waste, erosion
- 39Discuss the economic and social justice issues that can arise from some mining operations.The people who mind don't get the benefit from the products they mine.they often fule local conflict and are used by corrupt govt, and even warlords to fund themselves.
- 40The relation between plate tectonics, volcanic activity, tsunamis, and earthquakes.Tectonic plates are huge sliding discs of the surface of the earth that is responsible for the different landscapes we get. There are three main types of boundaries, convergent, divergent and transform boundaries. Convergent boundaries moves towards each other. Divergent boundaries move away. And transform boundaries slide past one another. Subduction zones in convergent boundaries is the main cause of volcanoes. Any boundary can cause earthquakes however the fault at a transform boundary is most known for causing earthquakes. Lastly Tsunamis are caused by undersea volcanoes, and earthquakes.
