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 ... qq2360767588. Chapter 5-Ancient Greece. 34 terms. zachdevine02.

era = A unit of time shorter than an eon but longer than a period. period = A unit of time shorter than an era but longer than epoch. epoch = A unit of time shorter than a period but longer than an age. Archean = “Ancient” eon from 4,500 Mya – 2,500 Ma. Proterozoic = “Early life” eon from 2,500 Ma – 540 Ma. The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series.The Cretaceous is named after creta, the Latin word for the white limestone known as chalk.The chalk of northern France and the white cliffs of south …The time scale is divided into eons, eras, periods, epoch, and ages. This can be likened to how our regular calendar is divided into months, weeks, and days. Unlike the years, months, and weeks we are familiar with, these times are not equally divided. Thus some periods are longer than some and some eras cover more time than others.
