The history of the earth is broken up into a hierarchical set of divisions for describing geologic time. As increasingly smaller units of time, the generally accepted divisions are eon, era, period, epoch, age. In the time scale shown at left, only the two highest levels of this hierarchy are represented. The Phanerozoic Eon is shown along the ...Chapter 11 A & B.

For example, the entire age of the earth is divided into four eons: the Hadean Eon, the Archean Eon, the Proterozoic Eon, and the Phanerozoic Eon. These four eons are further subdivided into eras (Table 7.3). Hadean, Ordovician, Triassic, Cenozoic. Arrange the following time units from largest to smallest. Eon, era, period,epoch.

Organization. In the geologic time scale, the youngest ages are on the top and the oldest on the bottom. The time scale is based upon relative times, therefore there aren’t any specific times listed with each era. The timescale is divided into eons, each eon into eras, each era into periods, and each period into epochs. Organization. In the geologic time scale, the youngest ages are on the top and the oldest on the bottom. The time scale is based upon relative times, therefore there aren’t any specific times listed with each era. The timescale is divided into eons, each eon into eras, each era into periods, and each period into epochs. This is approximately what fraction of geologic time? One-millionth.
