Earth Quake Waves

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
