You have collected data on seismic-wave velocities in rocks that exist a few hundred meters below the surface
Use information in Figure 8.18 to determine what kind of rock(s) is suggested by these P-wave velocities: 2.25 km/s; 4 km/s; 6.25 km/s; 6.75 km/s; 8 km/s.
What will be an ideal response?
2.25 km/s = unconsolidated sediment or sandstone or limestone
4 km/s = sandstone or limestone
6.25 km/s = granite
6.75 km/s = basalt or lower continental-crust metamorphic rocks
8 km/s = peridotite
