Where the crust is destroyed
Dense oceanic crust slides under less dense continental crust
the mantle and core are composed of different material
P waves refract as they travel through Earth. The shadow zone exists because of seismic waves. The shadows show when the earth spins around.
A strike-slip fault generally occurs at a transform boundary

Wandering with no pattern

. The south magnetic pole of the compass points to Earth's north magnetic pole.
The weight of the rocks above the mantle results in high pressure.
Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.
There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.
Continents cannot cut through the ocean floor.
high presure and heat
compass magnets can be deflected by earths magnetic field or other permanent magnets
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.

The continental crust is up to 70 km thick.
