How We Name The Divisions of Time In the early 1800’s a system for naming geologic time periods was devised using four periods of geologic time. They were named using Latin root words, Primary ... Sep 23, 2023 · Eras are divisions of geologic time shorter than eons but longer than periods. In terms of geochronological units, there are 10 defined eras that generally span several hundred million years. For example, the Paleozoic , Mesozoic , and Cenozoic eras are within the Phanerozoic Eon. To make geologic time easier to comprehend, geologists divided the 4.6 billion years of Earth’s history into units of time called eons. Then they further divided the eons into two or more eras, eras into two or more periods, periods into two or more epochs, and epochs into two or more ages. These units are called geochronologic units, (geo ...
