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

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

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.

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.
