What type of fault is the San Andreas?

• Convergent
• Transform
• Optimus Prime
• Divergent

The most destructive type of wave is a 

• P-wave
• S-wave
• Surface wave
• transverse wave

What is the area directly above the spot where the Earthquake actually occurs? (It is on Earth's surface.) 

• Epicenter
• Focus
• Fault
• Triangulation

What type of seismic wave travels compressionally? 

• P wave
• S wave
• Surface
• None

The seismic wave that allowed scientists to discover the liquid part of the core are the

• S-waves
• P-waves
• Love waves
• Rayleigh waves

The Richter scale measures:

• the amount of radon gas released
• the movement of plates
• the strength of an earthquake
• the weight of tectonic plates

An earthquake scored high on the Richter scale but low on the Mercalli scale. Why?

• it probably happened in an area with no people
• it was a fast earthquake
• because it damaged a lot
• impossible to tell

Liquefaction is when...

• the soil behaves like liquid
• the ground becomes liquid
• magma rises to the surface
• buildings are damaged, crumbling like liquid

An instrument that detects and measures earthquakes is a 

• seismogram
• focus seismic map
• focus
• seismograph 

How much bigger is a magnitude 8 earthquake compared to magnitude 7 one on the Richter Scale?

• 1 time bigger
• 10 times bigger
• 100 times bigger
• 1000 times bigger
