Natural Resources by 4FVB4h5



   Natural resources are natural
assets (raw materials) occurring in
    nature that can be used for
      economic production or
            Human centric
 Earth’s naturally occurring assets that
  provide us benefits through the provision of
  raw materials and energy used in economic
  activity (or that may provide such benefits
  one day) and that are subject primarily to
  quantitative depletion through human use.

 In other words, they will be used by
  humans for economic gain and we may one
  day run out.
Categories of Natural Resources
 Mineral and Energy Resources
 Soil Resources
 Water Resources
 Biological Resources
Natural Resources
 Things people and other organisms
  obtain from the living and nonliving
 Resources provide for the needs and
  wants of a population (group of the
  same kind of organism).
 All plants and animals depend on the
  resources in their environments to
  live, grow and reproduce.
Mineral Resources ???????
 Brainstorm mineral and use.
Minerals & Rocks
Minerals & Rocks
Minerals & Rocks
 Red Rocks Amphitheater, Morrison CO
Energy Resources?????????
 Brainstorm energy resources –
  Renewable or Nonrenewable???
Nonrenewable Energy Resources
Renewable Energy Resources
Soil Resources???????????
 Brainstorm – what’s up with this?
Food for thought…
What regions have good soils?
Water Resources????????????
 Brainstorm water sources and
  whether they are potable. (What is
Water as a Natural Resource…
 97% of water on Earth is saline.
 2.4% of water on Earth is in glaciers.
 0.45% of water on Earth is in the ground
 0.15% of water of Earth is in lakes and
 At any given time, 0.003% of the 0.60% of
  groundwater and water and lakes &
  streams is potable – fit for human usage
 This is literally a “drop in the bucket”
The Great Lakes hold 20% of
available fresh water on Earth
Biological Resources???????
 Brainstorm
Biological Resources
 Quality of plants will be limited by
  available water and the quality of soil.
 If handled wisely, largely renewable.
 Cutting edge technologies are
  stemming from the use of many
  plants, however, many unforeseen
  problems are also arising.
Biological Resources
Transformation of
                Natural Resources

 People use some resources
  without much modification
   Air for breathing
   Fresh fruits and vegetables
   Some spring water for
Transformation of
                Natural Resources
 People transform other resources to
  solve uniquely human problems.
   Timber & bricks for building
   Processing of raw foods into cooked &
    manufactured foods
   Processing surface water to make it
    clean for drinking
   Cleaning & weaving of flax, cotton &
    hemp for textiles and clothing.
     Manmade or Natural?
 Goals:
   To assess prior knowledge of students.
   To generate interest in types and properties of
   To help students develop their own
    definition/description of each material category.
   Practice classifying and justifying (critical
   Practice reasoning out the origin of the materials
    they are categorizing.
   To help students assess the origin of a material.

What do you need to know?

   What is a natural resource?
   What are the 4 main categories of natural resources?
   What is the purpose of a natural resource?
   What are some examples of mineral resources?
   What are some examples of energy resources and are
    they renewable?
   What is the importance of soil as a resource?
   What are examples of biological resources and some
    concerns about them?
   Give some examples of how some natural resources
    (mineral, energy, biological, hydrological) are
    modified (processed or treated) for our use.
   Can you identify manmade vs. natural materials and
    identify their origin?
