Final answer:
The oceanic lithosphere exhibits both P-wave and S-wave velocities, with P-waves traveling faster than S-waves. P-waves have speeds of 4 to 7 km/s and S-waves have speeds of 2 to 5 km/s. The velocity of these seismic waves can vary depending on the rigidity of the material they are traveling through.
Step-by-step explanation:
The oceanic lithosphere exhibits the velocity of seismic waves known as P-waves and S-waves. P-waves, or pressure waves, travel faster than S-waves, or shear waves, through the oceanic lithosphere.
In general, P-waves have speeds of 4 to 7 km/s, while S-waves have speeds of 2 to 5 km/s. Both types of waves are faster in more rigid materials like granite, but travel slower in less rigid materials such as sediments.
