Using the Earth’s resources

Cards (29)

  • Renewable resources can be replaced as quickly as they are used
  • Fossil fuels form much slower than they are being used
  • Resources used for biofuels
    • Wood chips
  • Humans use the earth's resources
    1. Provide warmth
    2. Shelter
    3. Food
    4. Transport
  • Around two-thirds of the rubber used in the world is now synthetic
  • Human activities need to be sustainable
    We can meet our needs without preventing future generations from meeting theirs
  • Huge amounts of metal are extracted from the Earth's crust
  • Synthetic rubber is produced using crude oil
  • If metals continue to be used at the current rate, they will run out
  • Chemistry's role in using resources
    • Artificial fertilizers to grow more food
    • Providing safe drinking water
    • Processes like phyto mining and bio leaching to extract metals more efficiently
  • Metals are also a finite resource
  • Natural rubber comes from the sap of a tree
  • Wood is a renewable resource
  • Chemistry replacing natural resources with synthetic alternatives
    • Rubber
  • Resources produced by agriculture and farming
    • Cotton
    • Trees for timber or fuel
  • Fossil fuels are a finite resource
  • If fossil fuels continue to be used at the current rate, they will run out
  • What are the main sources of finite resource?
    • the Earth’s crust
    • oceans
    • atmosphere
  • What are the main uses of finite resources?
    • provide energy
    • provide useful materials
  • Give one example of finite resource.
    • Crude oil
  • Which method of extraction uses organisms that absorb metal compunds?
    • phytomining
    • bioleaching
  • What are the main functions of synthetic products?
    • supplement natural products
    • replace natural products
  • What are leachates?
    • Copper-rich solutions made during bioleaching
  • What is bioleaching?
    • The use of bacteria to absorb copper compounds and make leachates
    • A type of metal extraction
  • What is phytomining?
    • A type of metal extraction
    • Grow plants which absorb metal ions through their roots
    • Plants are then harvested and burnt to produce ash that contains the metal compound
  • What is unsustainable development?
    • Meets the needs of current generations
    • Without compromising the ability of future generations to meet their own needs
  • What does the agriculture industry provides resources for?
    • Food
    • Timber
    • Clothing
    • Fuels
  • What is renewable resource?
    • Sustainable: can be removed from the environment without running out
  • Why might a tyre manufacturer choose to use synthetic rubber instead of natural rubber?
    • Properties of natural rubber cannot be controlled
    • Synthetic rubber is easier to make
