Supereon is the longest classification of time in geology. The Precambrian period is a supereon comprised of the Hadean, Archean, and Proterazoic eons.
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.
Eons are the longest subdivision of geologic time. They are typically divided into eras, which are further divided into periods, epochs, and ages. Eons represent the largest time divisions in the geologic time scale.
The correct order representing units of geologic time in increasing order is B. Eon, era, period, epoch. This hierarchy reflects the largest to smallest divisions of geologic time, with eons being the longest intervals and epochs being the shortest.
The eon after the Hadean Eon is the Archean Eon. During this eon, significant geological and biological events took place, leading to the development of early life forms on Earth.

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.
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.

An eon. There 5 eons of time.
Supereon is the longest classification of time in geology. The Precambrian period is a supereon comprised of the Hadean, Archean, and Proterazoic eons.
There are two: EON which is the first, and then the second EONA.
The longest span of time is generally considered to be the age of the universe, which is estimated to be around 13.8 billion years.
The order of units of geologic time from longest to shortest is: eon, era, period, epoch.
The longest segments of geologic time are eons, which are divided into eras, which are further divided into periods, epochs, and ages. The current eon, the Phanerozoic Eon, has been ongoing for approximately the last 542 million years.
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.
