Question

Quizplus · Accepted Answer

The primary technique used by geologists and geophysicists to probe the structure of Earth's core and mantle is the study of the deflection of seismic waves from earthquakes. This is known as seismology, and it provides valuable information about the composition, density, and temperature of the Earth's interior. X-ray analysis from satellites and extrapolation of surface features are not used to probe the Earth's interior, while direct sampling of interior rock is limited to the uppermost mantle and oceanic crust through drilling.
