P and S Waves

What was the origin time for an earthquake whose p-waves arrived at 02:54:40 pm at a seismic station in Buffalo, NY and it was determined the epicenter was 2000 km away?

• 03:02:00 pm

• 02:57:50

• 02:58:50 pm

• 02:50:30 pm

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

• 1900 km

• 4 minutes

• 7 minutes and 20 seconds

• 4000 km

It can travel through solids only

• Love waves

• Rayleigh waves

• Primary waves

• Secondary waves

Which of the following statements BEST describes secondary waves (S-waves)?

• circular motions like an ocean wave

• snake-like motions parallel to the Earth's surface

• contractions and expansions that are in the direction of wave propagation

• shearing motions that are at right angles to the direction of wave propagation

The first waves to arrive at any location (the faster waves) from the epicenter is...

• P-wave

• S-wave

• L-wave

• Both p-wave and s-wave

S waves travel slower than P waves

• True

• False

S-waves transfer energy

• forward and backward

• side to side

• both forward and backward and side to side

• neither, they do not transfer energy

We know the outer core is liquid because... (pick two)

• S waves cannot travel through it.

• P wave speed up going through it

• S waves can travel through it.

• P wave slow down going through it

P and S waves are body waves caused by

• oceans

• mountains

• the tides

• Earthquakes
