A p-wave traveled for 3200 km to reach a seismic station. How long had it traveled for?

• 00:01:60

• 00:04:50

• 00:10:40

• 00:05:50

An earthquake occurs 6800 km from the seismic station which recorded the p and s-waves recordings. What was the time difference between the arrival times of the p and s-waves?

• 00:10:10

• 00:08:20

• 00:18:40

• 00:014:40

If the p-waves arrive at 03:22:43 and the s-waves arrive at 03:29:57, what is the time difference between their arrivals?

• 00:14:07

• 00:07:14

• 03:07:14

• 00:07:00

The p-waves of an earthquake arrived at a seismic station at 08:55:50 and the s-waves arrived at 09:03:40. What is the distance to the epicenter from this seismic station?

• 4700 km

• 6100 km

• 2200 km

• 750 km

Which city is closest to the epicenter?  

• A
• B
• C

The difference in P and S wave arrival times at a seismic station is 8 minutes. What is the distance to the epicenter?

• 2,200 km

• 6,300 km

• 6,600 km

• 4,600 km

What will be the distance traveled by a P wave in 3 minutes?

• 700 km

• 1,200 km

• 1,400 km

• 5,400 km

How long does it take for the P wave to travel 2000 km?

• 1900 km

• 4 minutes

• 7 minutes and 20 seconds

• 4000 km

How far does a S wave travel in 10 minutes?

• 23 min and 10 seconds

• 3,000 km

• 6,600 km

• 6,300 km

What happens to the time difference between primary and secondary was as the distance traveled gets longer?

• time time difference remains the same

• the time differences increases

• the time difference decreases

• the time difference increases than decreases
