Slide 4 - Slide

What types of natural disasters do you know?

Slide 5 - Open question

There are two types of natural disasters. Which two types you think?

Slide 6 - Open question

Exogenic
Two exogenic forces:

Changes earth's crust caused by weather. 

Slide 7 - Slide

Endogenic force: Plate tectonics

Slide 8 - Slide

Note!!!


Endo
genic force: forces from the inside: earthquakes, volcano's caused by convection currents.

Exogenic force: force from the outside: caused by weather.

Explain what a natural disaster is

Slide 14 - Open question

Natural disaster
A natural disaster is caused by nature which can cause widespread damage and many casualties.

Slide 15 - Slide

What situation qualifies as a natural disaster?
A
An earthquake in Japan caused 100,000 euros of damage. There were 800 casualties
B
A fire broke in a shed in Maarsen after it was struck by lightning no injuries are known
C
Four hotels were completely destroyed by an avalanche in Austria. No one was hurt
D
Due to a strong wind, a large clock has fallen from the Dom toren. There is one casualtie.

Slide 16 - Quiz

Natural disasters can be caused by two different things: which two?

Slide 17 - Open question

Forces that change the earth's crust

Exogenic force= 
From the outside
Endogenic force=
from the inside

Slide 18 - Slide

What causes plates to move?
A
Convection current
B
Convection stream
C
Exogenic force
D
Subduction

Slide 19 - Quiz

Slide 20 - Slide

What are three plate movements?

Slide 21 - Open question

Divergent
Convergent
Transform

Slide 22 - Drag question

Slide 23 - Slide

Slide 24 - Slide

Slide 25 - Slide

Slide 26 - Slide

Types of plates 
Note:
Oceanic plate:
- Very heavy!

Continental plate:
- Lighter than oceanic plate. 

Slide 27 - Slide

Subduction
The heavy oceanic plate is
 forced under the continental
plate. 

The oceanic plate melts >
 becomes magma

Magma rises to the surface and creates a volcano. 



Slide 28 - Slide

Plate boundaries

Slide 29 - Slide

Slide 30 - Video

Note!
Convection current

=  the flow of molten rock under the earths crust.


Slide 31 - Slide

Convergent plate boundary
Because of this movement mountain chains will eventually develop in the regions next to the convergent boundary.

The Alps are an example of such a mountain chain. 


Slide 32 - Slide

Divergent plate boundary
Two tectonic plates which move apart.

Oceanic ridge
Underwater mountains formed by a divergent plate boundary.

Slide 33 - Slide

Transform plate boundary

Where 2 tectonic plates slide alongside each other .

Earthquakes are common

Slide 34 - Slide

Draw the directions of plate movement
1.Convergent

2.Divergent

3.Transform

Japan is a ...1......country in East Asia. It is part of the ring of fire 
The ring of fire is an....2.....shaped ring around the pacific plate. Along the plate boundaries you can find multiple......3.....
