A terminology has evolved covering the early years of the Earth's existence, as radiometric dating has allowed absolute dates to be assigned to specific formations and features. The Precambrian is divided into three eons: the Hadean (4567.3–4000 Ma), Archean (4000-2500 Ma) and Proterozoic (2500-538.8 Ma).

A summary of the Archean Eon. The Archean Eon marked a time when Earth’s climate began to stabilize. Earth cooled down from its molten state. It eventually could support oceans. Tectonic activity built continents. In the Archean Eon, oxygen filled the atmosphere, and most of the world’s iron ore was deposited.

Orders of magnitude (time) An order of magnitude of time is usually a decimal prefix or decimal order-of-magnitude quantity together with a base unit of time, like a microsecond or a million years. In some cases, the order of magnitude may be implied (usually 1), like a "second" or "year". In other cases, the quantity name implies the base unit ...The history of the Earth is divided as follows: 4 "aeons" or "eons" that last between 540 Myr (Myr = million years) and 2 Byr (Byr = billion years). Each aeon is subdivided into three or four "eras" of a few hundred million years (> 100 Myr). An era divides three or four "periods" of a few tens of millions of years (> 10 Myr)Aeon can also refer to the four aeons on the geologic time scale that make up the Earth's history, the Hadean, Archean, Proterozoic, and the current aeon, Phanerozoic.
