1. Pangea and the falling apart

2. Dinosaurs extinction and consequences

3. Determine absolute age (radio-activity)

4. Formation of fossil fuels

Slide 15 - Slide

Relative age

The age of a rock layer in comparison to the surrounding layers

Example: There are only trilobites in the lowest layer, so this must be the oldest
Absolute age

Based on chemical analysis, scientiest determine the 'exact' age of a rock or fossil

Example: This rock layer is 420 million years old

Slide 16 - Slide

Could layer 3 have been from the Ordovician, Jurassic or Tertiary?
relative age

Slide 17 - Slide

Topics for today (part of test) :

1. Pangea and the falling apart

2. Dinosaurs extinction and consequences

3. Determine absolute age (radio-activity)

4. Formation of fossil fuels

Slide 18 - Slide

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

Slide 19 - Slide

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

Slide 20 - Drag question

    coal
  natural gas
 crude oil

Slide 21 - Slide

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

Slide 22 - Drag question

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

2.9: The black gold

Slide 26 - Slide

Slide 27 - Slide

Thanks to what layer has Poetin become so rich?
A
impermeable layer above the oil field
B
impermeable layer below the oil field
C
there must have been a desert in the past
D
coal finally turned into gas

Slide 28 - Quiz

Slide 29 - Slide

Slide 31 - Drag question

Q. 3a: Give two reasons why the thin layer of clay with iridium is so important as evidence of the meteorite impact

Slide 32 - Open question

Slide 33 - Video

Why is the ozon layer so important for life?

Slide 34 - Open question

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

Slide 35 - Drag question

How did the meteorite impact cause mammals to flourish?

Slide 36 - Open question

Slide 37 - Slide

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

Slide 38 - Drag question

Slide 39 - Video

Put the process of coal formation in the correct order
1
2
3
5
6
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

Slide 40 - Drag question

Slide 41 - Slide

Drag the phases of associated gas formation in the right order
1
2
3
4
5
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
