Boundaries, Faults, & Earthquakes

What is a break in the lithosphere along which movement in an earthquake has first occurred?

• Earthquake
• Epicenter
• Fault
• Focus

Where is the point at which the first movement occurs during an earthquake?

• Epicenter
• Focus
• Fault
• Plate

Which type of wave is the first to arrive after an earthquake occurs?

• P Wave
• Rayleigh Wave
• S Wave
• Shear Wave

S Waves can move through which of the following?

• Gas
• Liquid
• Solid
• All of these

What is an instrument that detects and records waves produced by earthquakes? (This piece of equipment can measure the magnitude of an earthquake.)

• Epicenter
• Fault
• Seismogram
• Seismograph

What is the measure of the amount of energy released in an earthquake?

• Earthquake
• Epicenter
• Magnitude
• Seismogram

Which scale measures the intensity of the ground movement?

• Mercalli Scale
• Richter Scale
• Seismogram Scale
• Bernoulli Scale

What is the purpose of the three points in the center of the circles on the map?  

• They are a plot for predicting earthquake activity.  
• They calculate the speed of seismic waves. 
• They show the mountains most likely to be affected by earthquakes.  
• They are used to locate an earthquake's epicenter.

This famous transform fault is located in the western United States creates significant earthquake activity for California

• New Madrid
• Denali Fault
• Ramapo Seismic Zone
• San Andreas

The epicenter of an earthquake is

• The point below the surface where rock begins to break and the first motion occurs
• The seismic station closest to the earthquake
• The place where the greatest damage occurs
• The point on the surface directly above the focus
