The longest eon in Earth's history is the Precambrian, which spans from the formation of the Earth about 4.6 billion years ago to the start of the Cambrian period around 541 million years ago. This eon encompasses approximately 88% of Earth's geological time and includes the development of the planet's earliest rocks and the emergence of simple life forms. The Precambrian is subdivided into the Hadean, Archean, and Proterozoic eons, each marking significant geological and biological changes.

what is the longest and oldest era of earths history?
The Longest Era of Earths History is Paleoproterozoic Eralasting 900 million years.The largest unit of time in relation to Earth's history is the super-eon. Super-eons are divided into eons. Eons in turn are divided into eras, eras are divided into periods, periods into Epochs and Epochs in Ages.Precambrian Super-Eon (4,600 - 542 Ma)Hadean Eon (4,600 - 3,800 Ma)Archean Eon (3,800 - 2,500 Ma)Eoarchean Era (3,800 - 3,600 Ma)Paleoarchean Era (3,600 - 3,200 Ma)Mesoarchean Era (3,200 - 2,800 Ma)Neoarchean Era (2,800 - 2,500 Ma)Proterozoic Eon (2,500 - 542 Ma)Paleoproterozoic Era (2,500 - 1,600 Ma)Mesoproterozoic Era (1,600 - 1,000 Ma)Neoproterozoic Era (1,000 - 542 Ma)Modern Super-Eon (542 Ma - Now)Phanerozoic Eon (542 Ma - now)Paleozoic Era (542 -251 Ma)Mezozoic Era (251 - 65 Ma)Cenozoic Era (65 Ma - Now)

What is the longest division of geologic time?
The oldest division of geologic time is the Precambrian, specifically the Archaean Eon from which the oldest rocks and fossils date. (The Hadean Eon preceded the Archaean, but no geologic records date from this time because the Earth was cooling from a molten state.)
Which eon did most of earths history occur in?
Most of Earth's history occurred in the Proterozoic eon, which lasted from about 2.5 billion to 541 million years ago. This eon saw the rise of early life forms, the formation of continents, and significant changes in the Earth's atmosphere and oceans.
How long is an eon of time?
The longest division of geologic time, containing two or more eras.Answer:Although usually taken to mean just a very long time, astronomy and geology use eon to mean a billion years.
What is the largest subdivision of geologic time?
The longest in geological time is an Eon eg. Archeozoic Eon . Edit: there is also the supereon, which is usually composed of 2-3 eons.
How do you order the geologic time intervals to longest to shortest?
The geologic time intervals from longest to shortest are eon, era, period, epoch, and age. This hierarchical sequence represents the largest divisions (eons) to the smallest subdivisions (ages) of Earth's history.
Which division of geological time was the longest?
The Phanerozoic Eon is the longest division of geological time, spanning approximately the last 541 million years and continuing to the present day. It is further divided into three eras: the Paleozoic, Mesozoic, and Cenozoic eras.
What is the largest time period in the history of earth?
The Eon. We are currently in the 4th Eon.
