Which division of geological time was the longest?
The geologic time scale that represents the longest time span is the eon. It is a unit of time that is equal to a billion years.
How do you order the geologic time intervals to longest to shortest?
The order of the geologic time intervals is Eon, Era, Period, Epoch.
What is the longest subdivision in geologic time?
Eons I believe. Hope that helped! =)
when was the era of geologic time was the longest?
The Precambrian ... about 3 billion years.
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.)
What is the longest segments of geologic time called?
Precambrian Era.
Which division of geological time was the longest?
The geologic time scale that represents the longest time span is the eon. It is a unit of time that is equal to a billion years.
What types of evidence do scientist use in dividing geologic time into smaller time segments?
Iron precipitation is a chemical formula that scientists use in dividing geologic time into smaller time segments. They also use C14 dating to determine this.
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 order of the geologic time intervals is Eon, Era, Period, Epoch.
What era of the geologic time scale was the longest?
precambrian times

Which series of words describes length of geologic time from longest to shortest?
eon>era>period
How paleontologists use trilobites fossils as index fossils for various geologic time periods?
Trilobites were rapidly evolving and widespread marine organisms that spanned a number of geologic time periods. Certain types of trilobites only appeared in specific segments of geologic time; therefore, when one of these trilobites is found, you can be certain that the rock layer it is found in is of a certain geologic age.
