BOOK 5 UNIT 1.1

The tsunami that hit Japan on March 11, 2011, was the result of ​​ (a)  

• an earthquake in the Pacific Ocean
• 9.0 on the Richter Scale
• shifted by 10 inches
• tsunamis
• crash into each other
• built-up pressure is released
• 90% of all earthquakes ocur
• a plate drops below another in the sea

The earthquake measured (a)  

• 9.0 on the Richter Scale
• shifted by 10 inches
• tsunamis
• crash into each other
• built-up pressure is released
• 90% of all earthquakes ocur
• a plate drops below another in the sea

Because of the earthquake, the Earth's axis (a)  

• shifted by 10 inches
• tsunamis
• crash into each other
• built-up pressure is released
• 90% of all earthquakes ocur
• a plate drops below another in the sea

Not all the earthquakes cause (a)  

• tsunamis
• crash into each other
• built-up pressure is released
• 90% of all earthquakes ocur
• a plate drops below another in the sea

Earthquakes happen because the Earth's plates (a)  

• crash into each other
• built-up pressure is released
• 90% of all earthquakes ocur
• a plate drops below another in the sea
• tsunamis

When the edges of tectonic plates become unstuck, the (a)  

• built-up pressure is released
• 90% of all earthquakes ocur
• a plate drops below another in the sea
• tsunamis

The Pacific Ring of fire is the pates where (a)  

• 90% of all earthquakes ocur
• a plate drops below another in the sea
• tsunamis

A tsunami is caused when (a)  

• a plate drops below another in the sea
• tsunamis
