Chapter 14: Nonrenewable Mineral Resources
|
Section 1: What Are the Earth's Major Geological Processes and What are Mineral Resources?
Concept 14-1A: Dynamic processes within the earth and on its surface produce the mineral resources we depend on. Concept 14-1B: Mineral resources are nonrenewable because they are produced and renewed over millions of years mostly by the earth's rock cycle Section 2: How Long Might Supplies of Nonrenewable Mineral Resources Last?
Concept 14-2A: Nonrenewable mineral resources exist in finite amounts and can become economically depleted when it costs more than it is worth to find, extract, and process the remaining deposits. Concept 14-2B: There are several ways to extend supplies of mineral resources, but each of them is limited by economic and environmental factors. |
Section 3: What Are the Environmental Effects of Using Nonrenewable Mineral Resources?
Concept 14-3: Extracting minerals from the earth's crust and converting them into useful products can disturb the land, erode soils, produce large amounts of solid waste, and pollute the air, water, and soil. Section 4: How Can We Use Mineral Resources More Sustainably?
Concept 14-4: We can try to find substitutes for scarce resources, reduce resources waste, and recycle and reuse minerals. Section 5: What Are Earth's Major Geological Hazards?
Concept 14-5: Dynamic processes move matter within the earth and on its surface and can cause volcanic eruptions, earthquakes, tsunamis, erosion, and landslides. |
