From gravity and magnetic surveys and from seismic information.
Geologists have used two main types of evidence to learn about Earth's interior: direct evidence from rock samples and indirect evidence from siesmic waves.
no they use seismic waves

no
Studying how seismic waves refract inside the earth and if they "cast shadows" indicating that some layers inside earth are opaque to some types of seismic waves. Seismic waves "illuminate" the interior of the earth like light waves illuminate a room, permitting what is there to be seen if you have the correct tools to observe them.
