Question

Quizplus · Accepted Answer

Knowledge of Earth's interior is primarily derived from indirect evidence involving the analysis of seismic waves, which are generated by earthquakes and other sources and provide information about the structure and composition of the planet's interior. Direct sampling of the interior is not possible, as the deepest wells and boreholes have only penetrated a few kilometers into the crust, and work in caves and caverns does not provide information about the deeper layers of the planet. Historic and prehistoric records and mining records may provide information about surface features and events, but not the interior of the Earth.
