How do rock particles move during the passage of a Primary wave (P-waves) through the rock?
the particles do not move
in a rolling circular motion
back and forth parallel to the direction of wave travel
back and forth perpendicular to the direction of wave travel
Which of the following sequences correctly lists the different arrivals of the waves from first to the last?
P waves → S waves → Surface waves
Surface waves → P waves → S waves
P waves → Surface waves → S waves
S waves → P waves → Surface waves
What causes the up-and-down wiggles on the seismogram shown above?

Love wave
P wave
S wave
Surface wave
Which kind of waves does NOT travel through a liquid?
Love wave

Which of the following statements does BEST describe 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
Which layer of the Earth does S-waves do not travel?
core
crust
mantle

Which of the following earthquake waves can travel through both solids and fluids?
P waves only
S waves only
Q-waves only
Both P and S waves
What is the most destructive earthquake wave?
S waves
P waves
Q waves
Surface waves
Which statement best explains why the P-wave of an earthquake arrives at a seismic station before the S-wave?
The S wave originates from the earthquake focus.
The P wave has a greater velocity than the S wave.
The P wave originates from the earthquake epicenter.
The S wave decreases in velocity as it passes through the liquid.
What is the main cause of seismic waves?
earthquake
thunder
traffic
volcano
