Chapter 4: Natural disasters in Japan

Today

- Continue with 4.1

- Work on assignments chapter 4

Explain what a natural disaster is

What are the two types of forces that causes natural disasters?

Forces that change the earth's crust

Exogenic forces= 

From the outside

Endogenic forces=
from the inside

What causes plates to move?

1. Convection current
2. Convection stream
3. Exogenic force
4. Subduction

Convection current

Divergent

Convergent

Transform

Types of plates 

Oceanic plate:

- Very heavy!

Continental plate:

- Lighter than oceanic plate. 

Read 'Trenches and earthquakes' on page 63.

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. 

Homework for next week

Section 4.1 assignments 3,5,6,7 and 9 - homework for next week on Thursday!

Finished? Read 4.2 and start with the assignments!

Exogenic

Two exogenic forces:

Changes earth's crust caused by weather.

Natural disaster

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

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

What are three plate movements?

Note!

Convection current

=  the flow of molten rock under the earths crust.

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. 

Divergent plate boundary

Two tectonic plates which move apart.

Oceanic ridge

Underwater mountains formed by a divergent plate boundary.

Transform plate boundary

Where 2 tectonic plates slide alongside each other .

Earthquakes are common

Draw the directions of plate movement

1.Convergent

2.Divergent

3.Transform

Fill in the blanks: Apply the words Prosperous (welvarend), Jerky (schokkerig), Eruption (uitbarsting) ,Arc (Boog), Volcano

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.....

Plates collide not always very smooth, normally they have ....5.....movements and earthquakes are created.

 

Task

Paragraph 1 excersises 2,3,5,6,7 and 9

First 10 minutes in silence 

last 10 minutes of this lesson 

Now you are able to:

1. Explain what the ring of fire is

2.Draw the several directions of plate movement.

Languageaim: Explain what the words: prosperous, eruption, (shape of an) arc and jerky mean.

What is the driving force behind plate tectonics?

1. Convection currents
2. Sea
3. Mantle
4. Lava

Rain is an example of an

1. endogenic force
2. exogenic force

An earthquake is an ... force

1. endogenic
2. exogenic
