earth quake

A seismic station recorded the P-waves, but no S-waves, from an earthquake because S-waves were

• absorbed by Earth's outer core

• transmitted only through liquids

• weak and detected only at nearby locations

• not produced by this earthquake

Seismic station A is 5000 kilometers from the epicenter. What is the difference between the arrival time of the first P-wave and the arrival time of the first S-wave recorded at this station?

• 2 minutes 20 seconds

• 6 minutes 40 seconds

• 8 minutes 20 seconds

• 15 minutes 00 second

If a seismic station is 3200 km from an earthquake epicenter, which is the time needed for an S-wave to travel from the epicenter to the seismic station?

• 4 min 40 sec

• 6 min 0 sec

• 10 min 40 sec

• 11 min 10 sec

How long after receiving the first P-wave from an earthquake centered 4000 kilometers away does a seismic station receive its first S-wave from the same earthquake?

• 1 minute

• 5 minutes 35 seconds

• 7 minutes

• 12 minutes 40 seconds

A P-wave takes 5 minutes to travel from the epicenter of an earthquake to a seismic station. Approximately how many minutes will it take an S-wave to travel that same distance?

• 15 min

• 12 min

• 9 min

• 4 min

Which statement best explains why only one type of seismic wave was recorded at location B?

• S-waves cannot travel through the liquid inner core

• P-waves cannot travel through the solid outer core

• P-waves cannot travel through the solid inner core.

• S-waves cannot travel through the liquid outer core

An earthquake occurs at 10:05 a.m. At 10:09 a.m., the first P-wave from this earthquake is detected at a seismic station. Approximately how many kilometers (km) from the epicenter is this seismic station located?

• 1000 km

• 2000 km

• 2600 km

• 5600 km
