At the end of this lesson

you can explain why there are a lot of earthquakes and volcanoes in Japan

Natural disaster

How does an earthquake occur?

Plates move in three ways

1. Towards eachother (convergent). (Sometimes they collide, sometimes one dives under the other) 
2. Away from each other (divergent)
3. Past each other (transform)

1. Towards each other

• 2 plates that are evenly heavy: collide: a mountain forms (like the Alps)
• One plate is more heavy than the other. The heavy one dives under the light one. Through friction shocks can arise: an earthquake.
• The heavy part of the plate melts away into the earth and is pushed up: a volcano.

2. Away from each other

• A hole forms between the plates. Magma will flow slowly out of the earth. A effusive volcano forms (like Iceland)

3. Past each other

• The plates go past each other. This is not a smooth process, because the plates are bumpy. This causes friction: an earthquake can arise. 

To work

• Read 7.1: Japan: country in the Ring of Fire
• Make assignments 1 until 12 (from page 42 of workbook B)
