![Page 1: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/1.jpg)
Resources• What are resources?
• Resources are materials that can be used and have value
• What are some resources that people use?
• Fossil Fuels, Wind, Solar, Hydropower, etc…
• Food, crops, livestock

Resources
• Are people the only ones who use resources?
• What about animals and plants?

Resources
• What are some resources that animals use?
• Birds use twigs to build nests
• Beavers use trees to build dams
• Squirrels use acorns from trees

Resources• What about plants?
• Plants use water and nutrients from the soil;
• and carbon dioxide from the atmosphere
• And sunlight to make food

Resources
• Resources are classified based on time - in a lifetime:
• RENEWABLE: natural resources that can be recycled, renewed, or replaced
• food, trees, crops, oxygen, animals, water, etc …)
![Page 6: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/6.jpg)
Resources
• Resources are classified based on time - in a lifetime:
• NON-RENEWABLE: natural resources that when used take an extremely long time to replace (oil, coal, natural gas, & minerals)
![Page 7: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/7.jpg)
Resources
• Resources are classified based on time - in a lifetime:
• INEXHAUSTIBLE: natural renewable resources that cannot be used up and whose quality is not affected by use (solar, wind, ocean tides, etc)
![Page 8: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/8.jpg)
Resources
• Use the Science CutUps: Resources Rock! To review your knowledge on resources

Let’s try a sample TAKS question.

Fossil Fuels
• Watch the Fossil Fuels video clip
• Fossil fuels take a VERY long time to form
• Fossil fuels are a
• NON-RENEWABLE RESOURCE
• Let’s watch a short video on Fossil Fuels
![Page 12: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/12.jpg)
Fossil Fuels• How do they form?• Plants get their energy from the sun, die, get
buried and turn into fossil fuels – this takes millions of years
![Page 13: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/13.jpg)
Fossil Fuels
• There are three fossil fuels
• Coal
• formed billion years ago from plants that died but did not rot.
• Layers of dead plants accumulated and were covered by mud and then turned into rock – storing energy from plants that came from the sun.
![Page 14: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/14.jpg)
Fossil Fuels
• There are three fossil fuels
• Oil
• Formed from microscopic plants & animal in ancient seas.
• These plants and animal died, accumulated, were covered by mud and turned into rock - storing the energy that was in the plant or animal.
![Page 15: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/15.jpg)
Fossil Fuels
• There are three fossil fuels
• Natural Gas
• Form in a similar way as oil but it is much cleaner burning than coal or oil
• Natural Gas produces less pollution than coal or oil

Deposited FIRST so it is the OLDEST
Deposited SECOND so it is the 2ND OLDEST
Deposited LAST so it is the YOUNGEST
![Page 25: Resources What are resources? Resources are materials that can be used and have value What are some resources that people use? Fossil Fuels, Wind, Solar,](https://reader035.fdocuments.in/reader035/viewer/2022062408/56649f125503460f94c25cf3/html5/thumbnails/25.jpg)
This is in the top layer so it is the youngest
