Seismic data from all over the planet seem to indicate a p wave

Seismic data from all over the planet seem to indicate a P wave shadow zone that is much smaller than that on Earth, but no S wave shadow zone.

1. Based on the P and S wave info, what do you conclude about the structure of the interior of the planet relative to that of Earth?
2. Your magnetometer measures NO magnetic field. Are you surprised about this? (Think about previous answers).
