What type of boundary is associated with the shifting of plates?

• Transform plate boundary

• Convergent boundary

• Divergent boundary

• Static boundary

What is the ability of P-waves to travel through different states of matter?

• P-waves can only travel through solids

• P-waves can travel through solids, liquids, and gases

• P-waves cannot travel through liquids

• P-waves can only travel through gases

What is the relationship between S-waves and P-waves in terms of speed?

• S-waves are faster

• P-waves are faster

• They travel at the same speed

• S-waves do not travel

How do seismographs contribute to earthquake studies?

• By recording sound waves

• By detecting and recording seismic waves

• By measuring atmospheric pressure

• By tracking animal movements

What is the first step in determining the distance to an earthquake epicenter using a seismograph?

• Correlate the travel time with the spacing between the P and S-wave curves.

• Determine the time difference between P and S-waves.

• Place scrap paper along the y-axis.

• Look down to the x-axis to determine the epicenter distance.

What is the first step in determining the epicenter of an earthquake?

• Scientists use a single seismogram to find the epicenter.

• Scientists compare the amount of time that separates P and S-waves.

• Scientists create a circle on a map.

• Scientists examine the map for intersecting circles.

What do scientists do after determining the epicenter distance?

• They measure the earthquake's magnitude.

• They create a circle on a map.

• They record the earthquake's depth.

• They analyze the earthquake's duration.

How many minutes earlier did the earthquake occur if P-waves are recorded at 4:03 pm?

• 5 minutes

• 6 minutes

• 7 minutes

• 8 minutes
