WebHow do Geologists Learn About Earth's Interior? Geologists have used two types of evidence to learn about Earth's interior: direct evidence from rock samples and indirect evidence … WebScientists call this process core sampling. A core sample is a long narrow piece of rock obtained by drilling into a rock with a special tool that lifts out an intact part of the rock. In-depth study of core samples requires a science lab full of equipment – something we don’t yet have on Mars. So, we must return these samples to Earth for study.
