A Timeline of the Eons’s, Era’s, & Periods. The development of life over the last 3,700 million years of the Earth's history is one of the great stories told by modern science. During most of this time living things left only traces to indicate their existence. Then, about 544 million years ago, during what is referred to as the Cambrian ... Super Eons contain several Eons in them and cover extremely large periods of time. There has only been one Super Eon in Earth’s history. This one was the Precambrian Super Eon. It could be having been technically said that we are at the beginning of the next Super Eon.

Each aeon is subdivided into three or four "eras" of a few hundred million years (> 100 Myr).

Life on Earth inhabits a shockingly diverse range of conditions, from deep cold to caustic, boiling pools, but all appear to require liquid water. Scientists expect water to be essential to life on other worlds as well. Venus, otherwise Earth’s twin in size and rocky composition, orbits too close to the Sun, just inside the inner edge of the ...Formal geologic time begins with the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day. Modern geologic time scales also include the Hadean Eon (4.6 billion to 4.0 billion years ago). Hadean The Hadean ( IPA: / heɪˈdiːən, ˈheɪdiən / hay-DEE-ən, HAY-dee-ən) [ discuss] is the first and oldest of the four known geologic eons of Earth 's history. The Archean Eon (4 to 2.5 billion years ago) During the Archean Eon, methane droplets in the air shrouded the young Earth in a global haze. There was no oxygen gas on Earth. Oxygen was only in compounds such as water. Complex chemical reactions in the young oceans transformed carbon-containing molecules into simple, living cells that did not ...
Earth’s Timeline and History. 4,567,000,000 years ago, Earth was covered in molten lava. Earth was completely unrecognizable. In its earliest stage of formation, it was uninhabitable as it clumped from a cloud of dust. About 1,000,000,000 years ago, Earth had its first signs of life. Single-celled organisms consumed the sun’s energy.The Phanerozoic eon is the interval of geologic time spaning from the appearance of abundant, macroscopic, hard-shelled fossils, roughly 542 million years ago (mya), to the present time. Preceding the Phanerozoic eon is the Proterozoic eon, with the boundary between the two eons being determined by the "sudden" appearance in the fossil record ...…

A Timeline of the Eons’s, Era’s, & Periods. The development o Earth’s history is divided into a hierarchical series of smaller chunks of time, referred to as the geologic time scale. These divisions, in descending length of time, are called eons, eras, periods, epochs, and ages. These units are classified based on Earth’s rock layers, or strata, and the fossils found within them. From examining these fossils, …rocks on earth. These, with the Proterozoic Eon are called the Precambrian Eon. The remainder of geologic time, including present day, belongs to the Phanerozoic Eon. While the units making up the time scale are called geochronologic units, the actual rocks formed during those specific time intervals are called chronostratigraphic units. ...

Geologists generally agree that there are two major eons: the Precambrian eon and the Phanerozoic eon. The Precambrian goes from the formation of the earth to the time when multicellular organisms first appeared – that’s a really long time – from 4,500 million years ago to just about 543 million 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 deep time of Earth's past is divided into units according to events that took place in each period. ... The largest unit is the supereon, composed of eons. Eons are divided into eras, which are in turn divided into periods, epochs and ages.

The Eons In geochronology, time is generally measured in mya (million years ago), each unit representing the period of approximately 1,000, years in the past. The history of Earth is divided into four great eons, starting 4,540 mya with the formation of the planet. Each eon saw the most significant changes in Earth's composition, climate and life.In Buddhism, an "aeon" or mahakalpa (Sanskrit: महाकल्प) is often said to be 1,334,240,000 years, the life cycle of the world.. Christianity's idea of "eternal life" comes from the word for life, zōḗ (ζωή), and a form of aión (αἰών) [citation needed], which could mean life in the next aeon, the Kingdom of God, or Heaven, just as much as immortality, as in John 3:16.
