Title: NATURAL RESOURCES


1
NATURAL RESOURCES
  • The parts of the Earths environment that are
    useful or necessary for the survival of living
    organisms

2
NATURAL RESOURCES
  • Renewable Resources
  • Nearly Perpetual
  • Nonrenewable Resources

3
RENEWABLE RESOUCES
  • Any natural resource that is recycled or replaced
    by nature.
  • Plants, animals, water and other natural
    resources are constantly being recycled by
    natural processes

4
RENEWABLE RESOURCES
5
WATER CYCLE
6
NEARLY PERPETUAL RESOURCES
  • Any natural resource that is in constant supply.
  • Sunlight, wind, geothermal heat, tides and
    flowing water

7
PERPETUAL RESOURCES
8
NONRENEWABLE RESOURCES
  • Natural resources that are used up more quickly
    than they can be replaced by natural processes.
  • Fossil fuels (oil, coal, natural gas), minerals
    (iron, copper, phosphates)

NONRENEWABLE RESOURCES
10
THE THREE Rs OF CONSERVATION
  • REDUCE - use less of natural resources.
  • REUSE use an item more than once
  • without changing it or reprocessing it.
  • RECYCLE a form of reuse that requires changing
    or reprocessing and item or natural resource.

CONSERVATION
12
ALTERNATIVE ENERGY SOURCES
  • Energy sources used to reduce fossil fuel
    consumption.
  • Water (Hydroelectric) Power
  • Wind Power
  • Geothermal Power
  • Nuclear Power
  • Solar Power

13
WATER (Hydroelectric ) POWER
  • Electricity that is produced when the energy of
    falling water is used to turn the turbines of an
    electric generator.

14
WIND POWER
  • Electricity that is produced when winds blow at
    least 32km/h turning the turbines of an electric
    generator

15
GEOTHERMAL POWER
  • Electricity that is produced when the heat energy
    from the molten rock under the Earths surface is
    used to produce steam turning the turbines of an
    electric generator.

16
NUCLEAR POWER
  • Electricity that is produced when nuclear energy
    is released when billions of atomic nuclei from
    uranium, a radioactive element, are spit apart in
    a nuclear fission reaction turning the turbines
    of an electric generator.

17
SOLAR ENERGY
  • Electricity that is produced from photovoltaic
    cells that store the radiant energy form the Sun.
