Question:
Besides seismic waves from earthquakes, what other methods are used to find out
about the Earth's interior?
Replies:
Believe it or not, certain meteorites have given scientists clues about the Earth's interior.
Along with seismic data, the chemical and mineral information from these meteorites has given
scientists a pretty good idea of what is inside the Earth. There may be some information on a
NASA web site about this--I would suggest that you do a little searching there.

Geographical measurements of changes in the magnetic field of the earth, and sensitive
measurements of the local acceleration of gravity, measurement of residual magnetic fields in
magnetic rocks, analysis of volcanic eruptions all provide information about the interior of
the Earth of various sorts.
