P waves refract as they travel through Earth. The shadow zone
exists because of seismic waves. The shadows show when the earth
spins around.

Definition1/14
Samples of Earth's crust contain less iron than found in
meteorites, and iron is a comparatively heavy element that would
have sunk into the planet when it was being formed.
