when was the era of geologic time was the longest?
The Proterozoic Eon, which lasted from about 2.5 billion to 541 million years ago, was the longest geologic time era. It was a time of significant biological and geological evolution, including the emergence of early multicellular life forms.
What was the longest era?
The longest era in geologic time is the Precambrian era, which lasted from about 4.6 billion years ago to 541 million years ago. It encompasses about 90% of Earth's history and is divided into several eons, including the Hadean, Archean, and Proterozoic.
What is the Order the units or geologic time from the longest to the shortest?
The order of units of geologic time from longest to shortest is: eon, era, period, epoch.
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 series of words describes length of geologic time from longest to shortest?
eon>era>period

What era of the geologic time scale was the longest?
precambrian times
What is the longest segments of geologic time called?
Precambrian Era.

What are the units of geologic time from shortest to longest?
The units of geologic time, from shortest to longest, are as follows: epoch, period, era, and eon. An epoch is the smallest unit, representing a subdivision of a period, which is a division of an era. Eras are then grouped into eons, the largest units of geologic time that encompass significant spans of Earth's history.
Which series of words describes length of geologic time from longest to shortest?
eon>era>period
Which prehistoric era was the longest?
The earliest era of prehistory was also the longest. The Stone Age lasted from around 25,000 years to ago to about 5,500 years ago.
How many years is the Precambrian era?
The Precambrian era spanned approximately 4 billion years, making it the longest geologic time period in Earth's history.
What is the longest Eon in the Geologic Timescale?
The oldest eon of geologic time is the Archaean Eon of the Precambrian period. The oldest rocks and fossils date from this time, about 3.8 to 2.5 billion years ago. (Prior to that, the Hadean Eon began with the formation of the Earth. No geologic record exists from the Hadean, during which the Earth cooled from its molten state.)
Which Roman era lasted the longest the Roman monarchy the Roman Republic the Western Roman Empire or the Byzantine Empire?
The Byzantine Empire lasted for a millennium.
