  1. Chapter 1 - Lesson 4 Renewable and Nonrenewable Resources Chapter 1.4 Natural Resources

  2. Renewable and Nonrenewable Resourcespg 42 • All natural resources can be described as either renewable or nonrenewable Renewable resource – a resource that can be made again by nature or by people in a practical amount of time Nonrenewable resource – a resource that takes too long to replace or cannot be replaced at all

  3. Renewable and Nonrenewable Resourcespg 42 • Renewable resources Nonrenewable resources

  4. Renewable and Nonrenewable Resourcespg 43 Scarce – hard to find • Sometimes renewable resources become scarce when they are overused by humans • Fresh water replaces itself through the water cycle, but if humans use too much fresh water before it can be renewed through the water cycle, then it will become scarce • Trees can also suffer from overuse and become scarce if they are not replanted after being cut down or clear-cut

  5. Renewable and Nonrenewable Resourcespg 43 Conservation – the act of keep something from being lost or wasted • When we conserve our resources we are making sure that we only use them for reasons of necessity • Examples: planting new trees to replace the ones that were cut down, using less water to allow the water cycle to recover

  7. Renewable and Nonrenewable Resourcespg 43 • Cool Items made from • recycled materials:

  8. Why is it important to use natural resources wisely? (pg.43)

  9. Renewable and Nonrenewable Resourcespg44-45 • The best way to make our natural resources last as long as we need them is to try and find alternate resources that are underutilized • Solar, Wind, and Water are all examples of underutilized resources • We can use these natural resources to create electricity and we can stop using the fossil fuels and natural gases to conserve them

  10. How are the Sun, the wind, and the tides used as an energy source? (pg.44)

  11. Terms to Know • mineral natural resource . • Fertile soil fossil fuel . • Nonrenewable resource . • Renewable resource . • conservation . • Recycling biological resource • scarce . • How do groups that lack natural resources meet their needs? (pg. 45)
