Natural Resources

What are Natural Resources? Supplies from the nature. Everything on or around the Earth that we use to survive. For example: • Coal • Oil • Iron • Timber • Rivers • Animals • Sunlight

How do we classify natural resources? • Renewable resources • Nonrenewable resources • Inexhaustible resources

Renewable Resources • Things that can be replaced in a relatively short amount of time. • We must be wise about how we use these items! We could overuse, pollute, or destroy them too fast for them to be replaced. • Examples: plants, animals, water, air, soil

Nonrenewable Resources • Cannot be replaced in a short amount of time. • Made from dead plants and animals millions of years ago. • Once we use them up, they are gone forever. • We are using them faster than nature can replace them. • Examples: fossil fuels (oils, natural gas, coal) and minerals

Inexhaustible Resources • Those things that can be replaced as fast as they are used. • No matter how much we use, we can never run out. • Examples: sunlight, wind, and ocean tides.
