Question

Quizplus · Accepted Answer

Indirect evidence involving the analysis of seismic waves is the primary method for gaining knowledge of Earth's interior. Direct sampling of the interior using deep-test wells is not possible due to the extreme depth and pressure of the Earth's interior. Work in Earth's deepest caverns and caves would not provide information on the structure or composition of the interior. Historic and prehistoric records may provide some information on surface geology and past events but are not a reliable source for understanding Earth's interior.
