Study Notes
Earth Science - Grade 11 STEM - Unit 5: Energy Resources
- Unit 5 is about energy resources, focusing on mineral resources, nonrenewable energy resources, and renewable energy resources.
- Lesson 1 covers mineral resources, including identifying different types and how people obtain them.
- Mineral resources are categorized into metallic and nonmetallic.
- Metallic minerals include hematite and magnetite (used in steel), galena (used in car batteries and solder), gold, silver, and platinum (used in electronics, dental work, coins, jewelry, utensils, and bowls), chalcopyrite/copper (used in wiring, coins, and jewelry), and sphalerite/zinc (used in brass and galvanized steel).
- Nonmetallic minerals include diamond (used in drill bits, saws, and jewelry), graphite (used in pencils, paint, lubricants, and batteries), calcite (used in cement and building stone), halite (used in food preparation and preservation), kaolinite (used in ceramics, cement, and bricks) quartz (used in glass), sulfur (used in gunpowder, medicines, and rubber), and gypsum (used in plaster and wallboard).
- Different methods of mining are discussed. These include subsurface mining where miners work underground; surface mining where mineral deposits close to the surface are stripped away; placer deposits which involve dredging or removing sediments and debris from water bodies; and deep-sea, the most expensive and difficult, involving submarine mining technologies.
