4 Answer Key 1. C. renewable resources and nonrenewable resources 2. D. a renewable resource 3. C. produces air pollution when burned 4. A. geological processes 5. B. a form of stored sunlight produced by organisms that lived long ago 6. Sample: The advantages of using fossil fuels, such as petroleum, coal, and natural gas for energy, are that they burn easily and produce a lot of energy. They can be used to make electricity. They are available in many parts of the world. The disadvantages of using fossil fuels, such as petroleum, are that they cause air pollution and release greenhouse gases into the atmosphere. Burning coal also pollutes because it makes a byproduct that causes acid rain. Surface mining of coal can destroy landscapes. Also, coal mining harms miners' lungs. Fossil fuels are a non-renewable resource, so they are becoming more scarce and more expensive. 7. A. surface mining 8. D. diamond 9. A. dissolved minerals can re-form 10. D. mined for profit 11. B. deep mining 12. Sample: (One example from each category) In technology, minerals are used to make computer chips. Minerals such as copper, silver, and gold are used in electronic products. In industry, diamonds are used as abrasives in applications such as drilling. Metals for cars and airplanes and quartz and feldspar for glass come from minerals. In the arts, minerals are used to make pigments and dyes. Gold, silver, platinum, and other metals are used in jewelry. Gemstones are beautiful minerals often used in jewelry. 13. C. reusing natural resources 14. D. plastic bags 15. D. The amount of trash produced per person in the United States has nearly doubled over the last 40 years. 16. A. Choose products with the least packaging. 17. A. recycling 18. Sample: Recycling of aluminum cans, glass, and some plastics has two major advantages. Recycling saves resources. For example, recycling newspapers helps save trees used to make paper. Recycling also save energy. For example, a lot of energy is used to mine, refine, and manufacture the materials to make aluminum soft drink cans. Less energy is needed to make products from recycled materials than to make completely new products. However, it takes time, energy, and money to collect waste materials, sort them, and then to remake them. And some types of plastic and glass cannot be recycled. Unsaved Test, Version: 1 4

5 Standards Summary CA 6.6.c CA 6.6.b CA 6.6.a Students know the natural origin of the materials used to make common objects. Students know different natural energy and material resources, including air, soil, rocks, minerals, petroleum, fresh water, wildlife, and forests, and know how to classify them as renewable or nonrenewable. Students know the utility of energy sources is determined by factors that are involved in converting these sources to useful forms and the consequences of the conversion process.
