T3- planning

- Review homework questions

- repeating 2.9 'oil formation' (Q. 5 and 8 of WB 2.9)

- Explanation unconventional oil vs. conventional oil

Video: fracking

- exercises 3 and 4 from unit 2.10

For which number in the cross-section was the photo in source 47 (p.50) made? 1-2-3 or 4?

For which number in the cross-section was the photo in source 47 made? 1-2-3 or 4?

1. 1, because it is close to the surface and made during the carboniferous
2. 2, because it is deep in the ground and made during carboniferous
3. 3, because it is formed in the tertiary
4. 4, because it is deep and made in the tertiary

The cross-section was drawn from south-west to north-east.

Which description fits which part of the cross-section?

In this area, the carboniferous has subsided to a depth of 2 kilometres. This is the Ruhr valley graben

In this area, coal is locasted at a depth of about 500 to 600 metres

This area has subsided less deep to the north of Limburg. This is Venlo Graben

There were coal mines in this area, thanks to uplift

Unit 2.9: the black gold

2.10: unconventional oil

- oil formation

- location of oil: the continental shelf

How to extract oil - water drive and gas cap

- Example of unconventional oil: fracking!

Drag the condition of oil formation in the right order

Shallow sea containing a lot of plankton

A subsiding area

Thick layers of sediment so the plankton layer ends up in the oil window

Plankton is turned into crude oil in the parent rock

Migration (movement) of crude oil

An impenetrable layer that stops the crude oil

Q.8 (2.9)

Drag the phases of associated gas formation in the right order

Crude oil formation

New layers of sediment pressurize the parent rock

The pressure causes natural gas to form

The gas rises up towards the atmosphere

Except when there is an impenetrable layer above the gas, which keeps it inside the ground

Q. 5 (2.9)

Conventional and unconventional fossil fuels

Here you see a possible location of crude oil or natural gas

Drag the numbers from the cross section to the correct name

Tasks now

Read 'new deposits' of unit 2.10

Answer Q. 3 and 4 of unit 2.10

That was it!

Decide for yourself if you understood everything. 

To the right, you see the topics from this lesson. Are you ready for the test or do you still need help?

NO!

I really don't understand this

I still find this very difficult

I'm starting to get it!

I think I understand!

YES!

I am ready to do the test now

How fossils end up in rocks

How to extract fossil fuels like coal, , oil, gas, and shalegas from the ground.

How coalification works

How natural gas and crude oil are formed

How the extinction of the dinosaurs and the trilobites took place

How the evolution of life (animals and plants) took place

How fossils are used to decide the absolute and relative age of rocks
