1. Seismic Waves
2. P-Waves (Primary Waves)
3. S-Waves (Secondary Waves)
4. Wave Behaviour
* Reflection and refraction at boundaries between layers.
5. Detecting Seismic Waves
* Use of seismometers by seismologists.
* Analysis of travel times and detection locations.
* How S-wave shadow zones provide evidence for a liquid outer core.
* How P-wave paths and shadow zones refine the model of Earth's structure.
