§2.3 World: Mineral resources

Slide 1 - Diapositive

At the end of this lesson..
.. you know that it depends on the way of formation what types have evolved 

.. you understand the difference in formation between ores and fossil fuels 

.. you can indicate different resources by using maps 

Slide 2 - Diapositive

What are mineral resources?

Slide 3 - Question ouverte

What are mineral resources?
Sources we use that we win from underground

3 types:
1. Metals; iron, gold, lithium
2. Fossil fuels; coal, (crude) oil & gas
3. Various raw materials;salt, gravel, limestone


Slide 4 - Diapositive

What is the difference between mineral resources and raw materials

Slide 5 - Question ouverte

Slide 6 - Diapositive

1. Metals
Examples: iron, aluminium, tantaal, indium, lithium, cupper, chrome, nikkel, lead, zinc, tin, gold, silver and platina.

                                                       Metals are extracted from ores (ertsen)

Slide 7 - Diapositive

What are ores?
Minerals in which we find metal and from which we can extract a mineral resource. it 

So ....all ores are minerals, but not all minerals are ores .

Examples of ores are:
  • iron ore
  • cupper ore
  • silver ore
  • gold ore

Coalification:
Plants → peat → lignite → coal
                                                                                                   3 fases:

2
2. Door sedimentatie komt het veen steeds dieper te liggen. Met de diepte stijgt de temperatuur. Daardoor kan het pakket veen omgezet worden in bruinkool.
3
3. Wordt de druk en vooral temperatuur nog hoger, dan zal bruinkool veranderen in steenkool en gaat het laatste water en gas eruit. Deze 3 fases samen worden het inkolingsproces genoemd.
1
1. Afgestorven planten komen onder water te liggen, in een moeras. Door zuurstof te kort, verteren de planten niet. Er ontstaat veen.

Slide 16 - Diapositive

Climate  →  tropical 
Carboon: 350 tot 290 million ya
 jaar gelede
position →  around equator
→ Tropical swamp

Slide 17 - Diapositive

Formation oil

- dead plankton bottom sea
- covered by layers like sand
- high T and pressure turned it into crude oil

Together gas was formed


Slide 18 - Diapositive

3. Various mineral resources
Example: salt, gravel limestone

Slide 19 - Diapositive
