What is an eon of time
Sep 14, 2023 · Hadean Eon, informal division of the Precambrian occurring between about 4.6 billion and about 4.0 billion years ago. It was the time of Earth’s initial formation—the accretion of dust and gases, collisions with larger bodies, the stabilization of its core and crust, and the rise of its atmosphere and oceans. The time span of 4.5 billion years is divided into smaller segments or units called eons, eras, periods, epochs, and ages (Table 7.2). 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).
