G504 - Earthquakes

What is the main difference between P-waves and S-waves?

• P-waves are slower than S-waves
• P-waves can travel through solids, liquids, and gases, while S-waves can only travel through solids
• P-waves are transverse waves, while S-waves are compression waves
• P-waves cause more destruction than S-waves

Which type of seismic wave causes the most destruction during an earthquake?

• Surface waves
• S-waves
• P-waves
• All of the above

Which type of tectonic plate boundary is associated with the San Andreas Fault?

• Divergent boundaries
• Convergent boundaries
• Destructive boundaries
• Transform boundaries

What is the role of friction in causing earthquakes?

• It causes plates to move apart at divergent boundaries
• It causes plates to collide at convergent boundaries
• It causes plates to slide past each other at transform boundaries
• It causes plates to subduct at subduction zones

What is the relationship between seismic focus depth and earthquake magnitude?

• There is no relationship between focus depth and magnitude
• The shallower the focus, the higher the magnitude
• The deeper the focus, the greater the magnitude
• If the focus is in the core, the earthquake will be more destructive

Which type of seismic wave is the fastest?

• P-waves
• S-waves
• Surface waves
• All travel at the same speed

Which type of seismic wave can travel through solids, liquids, and gases?

• Surface waves
• P-waves
• S-waves
• All of the above

Which type of seismic wave causes particles to move perpendicular to the direction of the wave?

• Gamma rays
• S-waves
• P-waves
• All of the above

What is the main cause of earthquakes?

• Human activities
• Meteorite impacts
• Volcanic eruptions
• Movement of tectonic plates

What is the main difference between the Richter scale and the Moment Magnitude Scale?

• The Richter scale is used for small earthquakes, while the Moment Magnitude Scale is used for large earthquakes
• The Richter scale is more accurate than the Moment Magnitude Scale
• The Richter scale is based on observations, while the Moment Magnitude Scale is based on calculations
• The Richter scale measures the amplitude of seismic waves, while the Moment Magnitude Scale measures the total energy released by an earthquake
