8.3 How do we know ... how to determine velocities of seismic waves in rocks?
- The measures of velocity tell geologists that there are differences within Earth
- As these occur out of sight, experimentation must be used to deduce the details.
- Variations of rock type, temperature, and pressure are the primary variables in these experiments to measure in the lab and then extrapolate to Earth itself.
