The Earth
- The inner core is solid and very hot (5200-6200 degrees).
- The outer core is liquid. 
- The mantle is the thickest layer and this layer is solid, but can actually move over very long periods of time. 
- The crust is solid.  

Slide 7 - Slide

Tectonic plates
The movement of the tectonic plates is called plate tectonics. 
Places where two plates meet are called plate boundaries

Tectonic plate types
Two different plate types: 
- Oceanic plates
(basalt rock and very heavy)

- Continental plates
(granite rock and lightweight)

Exercises
Read paragraph 3.2 (any words you don't understand? let me know). 

Do the exercises 5 to 8. 

Slide 15 - Slide

Plate movements
Three different types of plate movements

Divergent plate boundary
Plates move away from each other and create new plate materials (basaltic rock).

Mid oceanic ridges from space
(divergent plate boundaries)

Three different types of plate movements

Convergent plate boundary
Folding the land and creating mountains.

Exercise 2
1. Explain why there are volcanoes in the south of Italy with geographical terms!
Use the atlas and your book as a source for your answer.
2. Give an explanation on why those volcanoes are explosive. Use the two websites, the atlas and your book as a source for your answer.
You may work in duo's.

Learning goals: 
- You can explain why an earthquake takes place somehwere. 
- You can describe the effect of earthquakes.

The whole system 

Slide 32 - Slide

Shaking earth
There's tension being build up between 2 plates that move towards each other or across each other. 
That tension releases energy in the form of shockwaves. 
--> this is an earthquake. 

Slide 33 - Slide

Slide 34 - Video

Richter scale
The size of an earthquake is measured on the Richter scale. 
If the magnitude (size) of the earthquake is high, it is likely to cause damage. 

Slide 35 - Slide

Effects of an earthquake
Aftershocks
Landslides
Liquefaction --> If the soil contains a lot of water, the soil starts to behave like a liquid and buildings and cars can sink into it. 

Slide 36 - Slide

Slide 37 - Video

Mercalli
To measure the effects of earthquake we use the Mercalli scale.

Learning goals: 
- You are able to explain the forming of a tsunami

- You know the different types of volcanoes and are able to correspond them with the different fault lines.

What do you know
about volcanoes?

Slide 41 - Mind map

Slide 42 - Video

Volcanoes
We find volcanoes at diverging boundaries and subduction boundaries. 

When magma exits the earth it's called an eruption. 

Slide 43 - Slide

Composite volcanoes
These volcanoes look like very steep mountains and can be very explosive (violent) volcanoes. 

Usually you'll encouter these volcanoes near subduction zones. 

Slide 44 - Slide

Shield volcano

Slide 45 - Slide

Secondary effects
Lahars --> Due to the temperature of the hot ash and gas from a volcanic eruption the snow will melt and cause mudflows. 
These mudflows are called: Lahars. 

The eruptions are also able the impact the climate, if it is a large eruption. 

Slide 46 - Slide

Slide 47 - Slide

Slide 48 - Video

Hot spots
There are also volcanoes that occur at places that are not near any plate boundaries. 

We call these volcanoes hot spots.

2.Fill in the keyword that you have to guess
3.Fill in the words you are not allowed to say
4.Give the set you created to your neighbours
5.Divide the cards, and give everyone the oppurtunity to talk about his keyword. The rest of the group guesses.
