Question

Mention the other sources of information about the structure of the earth.

Answer 1

Other sources of information about the structure of the earth include indirect methods such as the study of volcanic eruptions, seismic activity, and the analysis of meteorites. Volcanic lava and magma provide clues about the earth’s internal composition. Seismic waves generated by earthquakes travel through different earth layers and change velocity, allowing scientists to infer the structure inside. Meteorites, having similar composition to the earth’s interior, also inform scientists about the earth’s makeup. These indirect sources collectively help understand earth’s layers since direct access is impossible.
