Eons in order.

The Precambrian is an informal unit of geologic time, subdivided into three eons (Hadean, Archean, Proterozoic) of the geologic time scale. The Phanerozoic Eon is the most recent eon and began more than 500 million years ago. Phanerozoic- 538.8 to 0 million years ago. Proterozoic- 2,500 to 538.8 million years ago.The geologic time scale or geological time scale ( GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks). First, we need to be clear on what we mean by ‘mass extinction’. Extinctions are a normal part of evolution: they occur naturally and periodically over time. 1 There’s a natural background rate to the timing and frequency of extinctions: 10% of species are lost every million years; 30% every 10 million years; and 65% every 100 million years. 2 It would be wrong to assume that species ...Mass extinctions Classifying time 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.

Today, the geologic time scale is divided into major chunks of time called eons. Eons may be further divided into smaller chunks called eras, and each era is divided into periods. Figure 12.1 shows you what the geologic time scale looks like. We now live in the Phanerozoic eon, the Cenozoic era, and the Quarternary period. Aug 15, 2019 · Geologic time spans are divided into units and subunits, the largest of which are eons. Which is the longest Division of geologic time? The Geologic Time Scale is divided into four major units: Eons, Eras, Periods and Epochs. An Eon is the longest division of geologic time, so long in fact that there have only been four Eons.

The geologic time scale is the “calendar” for events in Earth’s history.
