Types of Natural Resources

1
Types of Natural Resources

• Nothing in nature is a resource. Some things
  become resources.
• Anonymous

2
Resources are Life

• Air, water, soil we must breathe, eat and have
  shelter to live.
• To meet our needs and wants we use resources
  in many different ways.
• Natural resources material that comes from our
  natural environment (raw)
• In economics needs demands wants supply

3
Types of Natural Resources

1. Renewable resources
2. Non- renewable resources
3. Flow resources

4
Renewable Resources
Soils

• Can replace themselves once they have been used.
• e.g. trees in a forest crops natural fish
  supplies
• THESE RESOURCES REGROW OR RENEW THEMSELVES IN A
  SHORT PERIOD OF TIME

Vegetation
Wildlife
5
Non- renewable Resources

• Gone once they are used
• e.g. minerals such as gold, iron, nickel fossil
  fuels such as coal and petroleum
• CAN ONLY BE CREATED UNDER VERY SPECIFIC CONDITIONS

Coal
Natural Gas
Petroleum
6
Flow Resources
Solar Energy
Wind

• Replaced by natural actions whether humans use
  them or not
• e.g. fresh water flowing through streams and
  rivers because of precipitation ocean currents
• EXIST B/C OF NATURAL SYSTEMS AND NATURAL
  PROCESSES

Waves, Tides
Air
Fresh water

Can resources overlap?

• Can a resource be a combination of two of the
  three types? YES.
• e.g. trees that cant be grown back b/c of
  farming activities can be classified as a
  non-renewable resource
• Other examples fish and minerals. Explain?

Fact File

• People in richer parts of the country use the
  most resources.
• In Canada, each individual uses up to 85 tonnes
  of natural resources per year!
• Thats more than 300 large shopping bags of
  natural resources per week!

You are important ?

• Recycling metals
• Aluminum pop cans are made from bauxite, a
  mineral dug from the ground.
• NOT recycling pop cans means that the bauxite is
  rapidly being used up, and will be gone forever!
• It also means that more energy (money and
  human/machine power) must be used to process the
  aluminum needed to replace the pop cans.

15
Recycling metals

• Saves valuable non-renewable minerals and energy
• It helps protect our natural environment

Almost all natural resources must be changed
before we use them.

• This is called PROCESSING.
• e.g. trees, iron ore, fish, crude oil.
• Refer to pg. 168 or your textbook, Figure 10.7

• Figure 10.8
• Looking at the four pictures, can you tell the
  story of how a pair of blue jeans is made?

19
Processing Resources

• E.g. A pair of blue jeans
• Step 1 cotton is grown and picked
• Step 2 cotton transported to mill and woven
  together to make thread
• Step 3 Large machines weave threads together to
  make fabric
• Step 4 cloth is dyed blue or black
• Step 5 shipped to a clothing manufacturer
• Step 6 fabric cut into shapes, sewn together,
  labels are attached- jeans shipped to store

20
Advanced Technology

• - Humans have learned over time how to process
  our natural resources to better meet our needs.
• As technology changes, sop does our use for
  natural resources.

E.g. CLOTHING

• (Figure 10.9)
• Early raw materials in environment. Animal
  skins, leaves, and bark. Processing cleaning and
  sharpening materials.
• Caveman/woman style clothing

22
E.g. CLOTHING

• (Figure 10.9)
• Middle weaves fabric out of plants material such
  as cotton and flax, or animal products like wool.
  Needs some processing of raw materials.
• Early settlers fur traders

23
E.g. CLOTHING

• (Figure 10.9)
• Modern makes fabrics and coverings out of
  human-made materials such as nylon. Raw materials
  include petroleum (which plastic is made from).
  Needs A LOT of processing!
