Earthquakes

The release of the stress that deformed the shape of the rock and allows rock to snap back to its normal shape is

• focus
• epicenter
• elastic rebound
• fault lines

The location inside the Earth where an earthquake originates is the 

• earthquake
• fault
• focus
• epicenter

A large crack in Earth's crust along which rock on either side move past each other is

• a focus
• a rift
• a fault
• a slip

Earthquakes are caused by 

•  divergent boundaries that are at rest 
• Convection currents of magma below the earth's surface
• The movement of tectonic plates causing stress on fault lines and elastic rebound
• Volcanic eruptions

If a set of railroad tracks becomes twisted by an earthquake, you can assume. 

• Boundaries have remained stable.
• Convergent boundaries have moved  to cause deformation. 
• Divergent boundaries have moved away from each other. 
• Boundaries have slipped beneath each other. 

Most of the earthquakes in Japan are a result of one plate sinking under another. This is a result of what kind of boundaries?

• convergent
• divergent
• transform
• sliding

The African Rift Valley is a location where plates are moving apart. This is an example of what kind of boundary? 

• convergent
• divergent
• transform
• sliding

The San Andreas fault is a location where tectonic plates move horizontally past each other. This is an example of what type of boundary? 

• convergent
• divergent
• transform
• slide

Which is NOT a result of earth's surface changing due to plate tectonic movement? 

• damaged buildings
• giant waves
• hurricanes
• shifting land

Evacuation times are often short for earthquakes because: 

• They don't happen often enough for us to study. 
• They mostly happen in the ocean.
• It is difficult to predict them because they happen so deep under the earth's surface. 
• They don't happen in places that we can study.
