Question

Quizplus · Accepted Answer

The geologic time scale was initially put together using the principles of superposition (the oldest rocks are on the bottom), fossil succession (the order in which fossils appear in the rock layers), and correlation (matching rock layers from different locations). Radiometric dating, carbon-14 age dating, lithostratigraphy, and biostratigraphy have all been used to refine and add to the time scale, but they were not the primary methods used to establish it.
