    Natural resources Natural resources Presentation Transcript

    • I. Earth’s Resources – resources that the Earth provides for us. A. Natural Resources – natural material that are used by humans.
    • 1. Examples – water, petroleum, minerals, forest, and animals 2. Most resources are changed and made into products that make people’s lives more comfortable and convenient 3. Energy we get from many of these resources, such as gasoline and wind, ultimately comes from the sun’s energy!
    • The sun is the POWERHOUSE  Would not have: 1. Trees 2. Wind 3. Fossil fuel 4. Plants 5. Animals
    • A. A renewable resource is a natural resource that can be replaced at the same rate at which the resource is used. 1. Examples: Trees and water
    • A. A nonrenewable resource is a resource that forms at a rate that is much slower than the rate at which it is consumed. 1. Examples: Coal, Petroleum, and natural gas
    • Non-renewable does NOT mean that it doesn’t renew. It means the rate at which it renews itself is SLOWER then the CONSUMPTION
    • A. Energy Conservation – most of the natural resources that provide us energy are nonrenewable resources
    • 1. To conserve natural resources, you should try to use them only when necessary. a. Turn the faucet on only to rinse you toothbrush b. Turn lights off when you are not using them c. Make sure washing machines are full before you start them d. Ride a bike, walk, or take a bus
    • B. Reduce, Reuse, and Recycle 1. Recycling – is the process of reusing materials from waste or scrap. (Examples: Newspaper, Aluminum cans, plastic, and cardboard) 2. Though energy is required to recycle materials, it takes less energy to recycle than it does to make new ones.
    • C. Conserving resources also means taking care of the resources even when you are not using them 1. Keep lakes, rivers, and other water resources free of pollution
