When p and s waves encounter the asthenosphere the velocity of the P and S waves change as they hit the asthenosphere.

Seismic velocities depend on the material properties like organization, mineral phase and pressing construction, temperature, and tension of the media through which seismic waves pass. Seismic waves travel all the more rapidly through denser materials and therefore by and large travel all the more rapidly with depth. Irregularly hot regions delayed down seismic waves. Seismic waves move more leisurely through a fluid than a strong. Liquid regions inside the Earth delayed down P waves and stop S waves on the grounds that their shearing movement can't be communicated through a fluid. To some extent liquid regions might dial back the P waves and constrict or debilitate S waves.

Whenever seismic waves pass between geologic layers with differentiating seismic velocities (when any wave goes through media with unmistakably contrasting velocities) reflections, refraction (bowing), and the development of new wave phases (e.g., a S wave created from a P wave) frequently result. Sudden leaps in seismic velocities across a limit are known as seismic discontinuities.
