What natural disasters
do you already know about?

Goals:

1.     You know what the Ring of Fire is
2.  You know which natural disasters occur regularly in Japan
3. You know what causes earthquakes and volcanoes to occur in Japan
4.  You can name the parts of a volcano
5. You can describe how an earthquake occurs

Basic book numbers: 97, 100, 102 (triangle)

Explain in your own words why Japan experiences many natural disasters.

There are two types of plates:
1. Earth plates (continental plates).
2. Sea plates (oceanic plates).

Plates move in three ways:

1. Alongside each other (transform)
2. Out of each other (divergent).
3. Toward each other (convergent)

convection currents

Under the Earth's crust you will find liquid rock: magma.

This magma is incredibly hot!

The heat creates currents inside the earth.

These are called convection currents.

Let's go to work!

Summary

• The Ring of Fire is the area around the Pacific Ocean where many earthquakes and volcanoes occur
• Cause: Earth's crust is constantly moving due to convection currents. 
  
• Plates move in three ways.
• Consequence: this causes earthquakes and volcanoes.
• Molten rock inside the earth is called magma, once it gets outside the earth's crust we call it lava.magma, zodra het buiten de aardkorst komt noemen we het lava.
