Learning objectives for these 3 weeks
  • You know how the Earth has changed over the past 4,5 billion years.
  • You can explain how rock layers and fossils tell a lot about the geological history of the Earth.
  • You can explain the difference between relative and absolute time.
  • You can mention several different types of mineral resources and can explain how they are formed.
  • You can explan why Europe is depend on other countries for mineral resources.
  • You can explain why the European list of critical resources is not the same as the list of worldwide scarce mineral resources.

Mineral resources
Substances we extract from earth that are useful to humans.
  • Metals -> ores originate from the mantle
  • Fossil fuels -> fossil fuels originate from plant material
  • Various raw materials (such as table salt) -> various origins, such as compressed shells (limestone)

# You can explan why Europe is depend on other countries for mineral resources.
What were the two most important mineral resources in the past?
  • coal
  • iron ore

Many coal mines in Europe have closed.
  • less demand for coal
  • bad for the environment
  • importing is cheaper

Slide 10 - Slide

# You can explan why Europe is depend on other countries for mineral resources.
For some mineral resources there are sufficient for European industry, for others there are shortages.
How are the shortages supplemented?
With imports from other countries

The European Union draws up a list of critical mineral resources every few years. What makes these mineral resources critical?
  • Economically important for Europe
  • Supply is not without risk

Slide 11 - Slide

# You can explain why the European list of critical resources is not the same as the list of worldwide scarce mineral resources.


Why are critical mineral resources economically important?
  • are used in almost all industries
  • are applied in modern technologies
  • are required for energy efficient applications

Slide 12 - Slide

# You can explain why the European list of critical resources is not the same as the list of worldwide scarce mineral resources.


What makes the supply of critical raw materials sometimes unreliable?
  • countries supplying mineral resources are involved in an armed conflict
    • the countries have an unreliable government
    • one or a few countries own the mineral resources and can determine the price they want to charge
    • countries need the mineral resources themselves, such as China, which is building its own economy
