1 Natural s Support Human Activity Notes: Chapter 10.1 Key Concept: Natural resources support human activity. Review: Life has inhabited Earth over the past 3 billion years. Natural resources provide materials and energy. 1)List some of the costs and benefits of using coal and cutting down trees for materials. Cost Benefit Burning Coal Cutting Down Forests Renewable s 2)Fill in the content frame with information that compares renewable and nonrenewable sources. s Similarities Differences Renewable Nonrenewable Nonrenewable s 3)If deposits are abundant, why is it important to conserve nonrenewable resources? Fossil Fuels supply most of society's energy. 4)What are the three main sources of energy used in the United States?

2 Which one supplies most of the country's energy needs? 5)Coal is mined in two different ways. List each way and one problem associated with each method. A. 1. B. 1. 6)How are oil and natural gas collected? (Use details please.) 7)Fossil fuels, minerals and plants supply materials for modern products. These materials come from three main sources list them here and provide examples of what they produce: s Can Be Conserved and Recycled Key Concept: s can be conserved and recycled. Review: Fossil fuels supply most of society's energy and products, but at a cost to the environment. Notes: Chapter 10.2 Conservation involves reducing waste and reusing natural resources. 1)How can you reuse products and reduce waste to conserve natural resources? )Complete the following for Conservation: Definition Characteristics:

3 Examples: Non-examples: 3)How can a person brushing their teeth conserve water? If a person saves an average of 10.5 gallons of water a week, how many gallons will be saved in 2 years?(hint 52 weeks in a year) 4)How does reusing a product save resources? 5)Many products can be used more than once, list a few: )Recycling involves recovering and extending natural resources. What are two possible uses for recycled plastic bottles? )What are some of the limitations of conservation and recycling programs? Energy Comes From Other Natural s Key Concept: Energy comes from other natural resources. Review: Conservation involves reducing waste and reuses natural resources. Recycling involves recovering materials that would ordinarily be thrown away. Notes: Chapter 10.3 Nuclear power is used to produce electricity. 1)Complete the following for Nuclear fission: Definition Characteristics: Examples: Non-examples:

4 2)Renewable resources are used to produce electricity and fuel. Why do renewable energy resources make up only a small portion of the energy used in the world? 3)Hydroelectric Energy -- How does damming a river end up creating electricity? )Hydroelectric energy What is it used for? _ What problems are posed for the environment? 5)Solar Energy -- What is a solar cell? 6)List one advantage and one disadvantage of using solar power. 7)Complete the following for Geothermal Energy: Definition Characteristics: Examples: Nonexamples: 8)Wind Energy--What is required to make wind farms successful? 9)What is the definition for biomass: 10)Hydrogen Fuel Cells--How does a hydrogen fuel cell produce electricity? What products does it produce: What are the by-products? Create Flashcards for the following 12 vocabulary words: Natural Renewable Nonrenewable Fossil Fuel
