Meteorites which are sometimes remnants of exploded planets reveal what the inner layers may consist of. Also of use in inferring the structure of Earth are the responses of seismic waves as they travel through the Earth and are recorded by scientific instruments. Mathematical calculations of Earth's density and its relation to our gravitational effects on the surrounding celestial bodies also plays a part in determing composition. And finally, the study of the magnetosphere, the magnetic field around the Earth which blocks harmful solar radiation, reveals the structure and interplay of the inner and outer core.
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 obtain indirect evidence about the earth's interior by reactions to seismic waves. They also use rock samples and drilling samples.

From gravity and magnetic surveys and from seismic information.
To study earth's interior, geologist often rely on indirect methods such as evidence from seismic waves, not fossils.

How do temp auteur and pressure change as you go deeper into earth
they use stuff like earthquakes and volcanoes to study it.
Geologists study the origins, physical history, and structure of earth.
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.
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.
they have used two methods direct and indirect. seismic waves are the forces produced when earthquakes occur.from rocks from deep inside earth they can give inferences about conditions deep inside earth. they also record the seismic waves and record how dast they travel through Earth this is an indirect method
