Q. 2: How does this dead fish becoming a fossil until it is found?

The soft parts perish

The fish remains are buried by layers of sediment

The sedimentary layers turn into rock

The rock is moved up to the surface

The fossil is removed from the rock with a hammer and chisel

Changing conditions

Consequences

Sufficient oxygen

Extinction of dinosaurs

Hunted by humans

Ozone layer that protects against UV

Meteorite impact

The rising cilimate temperature and changing landscape

The development of land plants

Extinction mammoth

Extinction dinosaurs

The strong rise of mammals

The development of land animals

Extinction of the tiger

What influences what? Put in the right order with correct explanation

Explanation 1>2

Explanation 2>3

Temperature on earth

Sea level

Volcanic activity

Due to CO2 increase temp. rises

Because it is hotter, ice melts and sea level rises

Question 7b

--> The higher the latitude, the lower the temperature

--> The bigger the continent, the dryer the centre of the continen

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

During the carboniferous: a major part of the world looked like this

Put the process of coal formation in the correct order

4

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

Q.2b

correct

incorrect

Thick layers of peat formed in the carboniferous

You can find coal in the carboniferous layers

Coalification occurs when the peat layers subside and sedimentary layers are deposited on top of the peat

The coalification took place during the carboniferous

The speed of subsidence and that of the sedimentation process do not influence the formation of coal

In the end, the coal layers were thicker than the peat layersl

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 carbinferous
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

Fossil fuels (unit 2.8 and 2.9)

Review Q.2 and 3 (unit 2.8)

Together: Q. 4 unit 2.8

Unit 2.9: oil formation and conditions for finding oil and associated gas

Homework: 2.8: Q. 4, 6 2.9: Q. 1,2,4,5,8,9

2.9: The black gold

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

Drag the numbers from the cross section to the correct name

Q.2a

impenetrable layer

Crude oil

Natural gas

Reservoir rock

Parent rock

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
