How do we know how to determine velocities of seismic waves in rocks?
What will be an ideal response?
Answer: "Laboratory experiments relate seismic-wave velocities to different types of rocks, under temperature and pressure conditions comparable to those in the deep interior of Earth. Seismic waves move more slowly in unconsolidated sediment than through sedimentary rocks, and they move even faster in igneous and metamorphic rocks. Within igneous rocks, felsic rocks transmit waves more solely than mafic rocks, and ultramafic rocks display the most rapid velocities."
