The largest expanse of geologic time is the "supereon," which is an informal term used to describe intervals of time longer than an eon. It encompasses the entire geologic time scale, which includes eons, eras, periods, and epochs. The current supereon is the "Hadean" or "Azoic" eon, which began with the formation of the Earth around 4.6 billion years ago.
The largest expanse of time on the geologic time scale is the eon, which is further divided into eras. Eons are the longest subdivisions of time, representing billions of years of Earth's history.
Eons are the largest division of geologic time, typically lasting hundreds of millions to billions of years. They are used to represent the greatest expanse of time in Earth's history.
Geologic time refers to the vast expanse of time over which Earth's history is recorded, characterized by different eons, eras, periods, and epochs. The geologic column, on the other hand, is a hypothetical representation of the Earth's rock layers and the fossils they contain, arranged in chronological order based on relative dating principles. Geologic time provides the framework for understanding the sequence of events in Earth's history, while the geologic column is a visual representation of this history based on the rock layers and fossils found in stratigraphic succession.
The presence or absence of fossils has been used to compare the relative ages of rocks around the world and to arrange sedimentary rocks into a geologic time scale. Eons are the largest intervals of the time scale and range from 540 to 2,050 million years in length
The longest subdivision in geologic time is the eon, which is further divided into eras. Eons represent the largest interval of time in the geologic time scale, such as the Phanerozoic eon which encompasses the last 541 million years.
Eon The largest expanse of time on the geologic time scale is the eon. An eon would encompass at least two eras.

The Precambrian
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 third largest division of geologic time is an era. The eras are further divided into periods, epochs, and ages.

Human existence is a mere blip in geologic time, which spans billions of years. While our time on Earth is relatively short compared to the age of the planet, human activities have had a significant impact on shaping the environment and the Earth's geological processes.
The current age of the universe - about 13.5 billion years - and getting longer.
No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
