Slide 1 - Tekstslide

What is the plan for today?

  • Finish paragraph 1
  • Repeat the most important parts

Slide 2 - Tekstslide

Goals of last lesson
  1. You are able to explain the differences between endogenic and exogenic forces.
  2. You can think of 2 examples for both endogenic and exogenic forces (G66).
  3. You can explain why shells and fossils can be found in the Alps.
  4. You can explain in 4 steps how the Alps are formed. 

Slide 3 - Tekstslide

Endogenic & exogenic forces
Endogenic forces
Forces from within the Earth, that changes the Earth's crust.

Exogenic forces
Forces from outside the Earth, that changes the Earth's crust.

Slide 4 - Tekstslide

Today's goals
  1. You can mention 3 differences between a young and an old mountain range.
  2. You know the 4 different reliefforms, with their height (G77).
  3. You can explain the process of the 3 types of weathering (G81).
  4. You can explain the erosive effect of weathered material in the mountains (G84).

Slide 7 - Tekstslide

Weathering
Open your notebook and work out the 3 kinds of weathering.

- What are the characteristics?
- What are the differences?

Slide 8 - Tekstslide

Weathering
You can explain the process of the 3 types of weathering (G81).
"The disintegration of rock as a result of weather and vegetation."

Slide 13 - Tekstslide

Slide 14 - Tekstslide

You know the 4 different reliefforms, with their height (G77).

Slide 15 - Tekstslide

Relief
0 - 200m - Lowland
200 - 500m - Hills
500 - 1500m - Low mountain range
1500 and above - High mountain range

Slide 16 - Tekstslide

Slide 17 - Tekstslide

Slide 18 - Tekstslide

5
100 million years ago: thick layers of dead animals and plants form in tropical sea.
80 million years ago: The African plate starts to move and pushes sedimentary rock out of the tropical sea to the north.
30 million years ago: The African plate collides with the Eurasian plate: formation of the Alps.

Slide 19 - Tekstslide

Plate movements

Slide 20 - Tekstslide

take note!
Three different movements:

Transform
Divergent
Convergent

Slide 21 - Tekstslide

Plate movements

Slide 22 - Tekstslide

Open G80

You can mention 3 differences between a young and an old mountain range.

Slide 23 - Tekstslide

Answer
Young mountain ranges are high with (1) steep slopes, (2) sharp peaks and (3) deep valleys.
Old mountain ranges have (1) gentle slopes and are (2) round at the top. (3) They are also much lower.

Young mountain ranges are still growing.

Slide 24 - Tekstslide

Young or old?

Slide 25 - Tekstslide

Young or old?

Slide 26 - Tekstslide

Let's go!
  • Read the text at page 24/25 of your coursebook.
  • Make exercises 6 to 9 of paragraph 1 at page 23 in your workbook.
  • Read GeoGuide numbers 81 & 84.
Rules while working:
  • You work alone and in silence.
  • Raise your finger if you've a question.
  • Always read the exercise well before you ask your question.
FINISHED? Open the list of knowledge and skill on your Chromebook and work out paragraph 1.
