Discuss with your neighbour

How did crude oil originate?

dead plankton lay at the bottom of the sea

plankton was covered by thick layers of sand

plankton was converted into crude oil by the pressure and temperature

take note

Discuss with your neighbour

1. Which two things were necessary for the oil to become an oil reserve?

2. Which other fossil fuel was created at the same time as the crude oil?

Discuss with your neighbour

1. Which two things were necessary for the oil to become an oil reserve?

- An impermeable layer (to trap the oil below)

- Plate tectonics creating a fold (a larger space)

2. Which other fossil fuel was created at the same time as the crude oil?

natural gas

take note

What is necessary for layers of sediment to keep on piling on top of each other?

1. The area needs to be flooded all the time
2. The area needs to be lower lying then the surrounding area
3. It needs to be windy so the wind can bring more sediment
4. An ice sheet compacts the sediments

Put the process of coal formation in the correct order

Dead trees and plant remains end up under water

A thick layer of plant and tree remains develops

The water lacks oxygen which stops the plants from rotting

Layers of sediment close off the plant remains from the atmosphere

The layer is pressed under high pressure and high temperature

The area subsides (goes down,, keeps becoming lower)

Natural gas

Coal

Crude oil

Consists off compressed plant material

Forms when plant and animal remains are pressed together

Consists of compressed material of animal remains

fossil fuels / energy sources

metallic resources

non-metallic resources

Copper

Iron ore

Silver cutlery at the dinner table

Coal

Gasoline to drive your car

Gravel

Marble

Sand

Metallic resources

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

                                                       Metals are extracted from ores

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
