This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
being oxidized to limonite (hydrous iron oxides), and also in a few areas the sand content is higher.
