Types of Natural Resources
  • A natural resource is something found in nature
    that people are able to use to meet their needs.
  • There are three types
  • Renewable Resources
  • Nonrenewable Resources
  • Inexhaustible Resources

Renewable Resources
  • A renewable resource is something that can be
    replaced.
  • A renewable resource can be replaced by natural
    processes.
  • Renewable resources must be given time to renew
    themselves.
  • Examples are forests, livestock, and food crops.

4
Nonrenewable Resources
  • A nonrenewable resource is something formed over
    a very long period of time.
  • Nonrenewable resources cannot be replaced or
    renewed.
  • Examples are oil, coal, copper, and other
    minerals.

5
Inexhaustible Resources
  • An inexhaustible resource is something with such
    a large supply that it cannot be used up by human
    activity.
  • Examples are energy from the sun, wind power, and
    heat from deep inside the Earth.
