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.

List some things that come from the Earth (natural resources) that help us live our lives. Cross off any items that you have on your list that another group mentions.
