Mr. Burton 3.4 Notes Please Grab:1. Your folder.2. Writing Utensil.3. Answer the following question: What is a natural resource?
How we use natural resources • A natural resource is any material in nature that people use and value. • Some are used as is. • Some are changed to make something new. • Renewable resources are resources Earth replaces naturally. • Nonrenewable resources are resources that cannot be replaced; they will run out one day. • People must manage resources to ensure they will be available in the future. • Deforestation, the clearing of trees, is a result of lack of management. • Reforestation, planting trees to replace lost forestland, works to prevent resource loss.
Fuel, Heat, Energy • Most energy we use comes from fossil fuels, nonrenewable resources that formed from the remains of ancient plants and animals. • Coal—pollutes the air; used mainly to create electricity at power plants • Petroleum, or oil—used to make fuels and other products • Natural gas—cleanest-burning fossil fuel; used mainly for heating and cooking • Will not run out • Generally better for the environment • Hydroelectric power—the production of electricity from waterpower—is the main alternative to fossil fuels. • Wind is used to power wind turbines that create electricity. • Solar power and geothermal energy—heat from within Earth—can heat water for homes and be turned into electricity.
Nuclear Energy • Obtained by splitting atoms, small particles of matter • Uses the metal uranium, so some consider it a nonrenewable resource • Produces dangerous wastes that must be stored for thousands of years before they are safe • Accidents at nuclear power plants have terrible effects.
Mineral Resources • Mineral resources include metals, salt, rocks, and gemstones. • Minerals fulfill countless needs. • Minerals are nonrenewable, and therefore need to be conserved. • Recycling can make the supply of mineral resources last longer.
People’s lives and Countries wealth via resources • The natural resources available to people affect their lifestyles and needs. • People in areas with many natural resources sometimes have more choices on ways to dress, eat, live, travel, and entertain themselves. • People in areas with fewer natural resources will likely have fewer choices and different needs. • Availability of natural resources affects countries’ economies. • The many resources available in the United States have helped it become one of the world’s wealthiest economies. • Countries with few natural resources often have weak economies. • Some countries have only one or two valuable resources but few others.
Exit Slip: 3-2-1 • Identify • Three (3) different types of resources. • Two (2) ways we use fuel, heat, or energy. • One (1) question you still have or “aha” moment.
