Geologists obtain indirect evidence about the earth's interior by reactions to seismic waves. They also use rock samples and drilling samples.

Measure pressure difference at earth surface
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.

Geologists use evidence from seismic waves to learn about earth's interior. Geologists record the seismic waves and study how they travel through earth. By Brianna.

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.
