∙ 14y agoThe geological time scale is the geologic history of the planet from formation to the present. It starts with large divisions of time called eons and is subdivided into successively smaller units of time based on dominant lifeforms, extinction events, even climate.

∙ 15y agoGeologic time spans the history of the planet Earth, from formation to the present, a period of around 4,600,000,000 years. The largest groupings of geologic time are eons, followed in descending order by era, period, epoch, and age.

∙ 13y agoVast stretches of time marked by broad changes in environment and biota delineate the various geologic epochs and eras.
For example, dinosaurs lived during the Mesozoic Era, which is further divided into the Triassic, Jurassic, and Cretaceous Epochs. We live in the Cenozoic Era, and the current Epoch is known as the Holocene. The Cenozoic is noted by a proliferation of flowering plants, as well as the terrestrial dominance of mammals.

Compare geologic time with geologic column?
a geologic time scale has eras, made up of periods, epochs, etc. hope this helps! :D
About 88 percent of geologic time is represented by the time span called what?
88 percent of geologic time is represented by the Precambrian time span.
How is the geologic time scale different from time scales that show human activities or accomplishments?
The units of geologic time are much longer
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 largest expanse of geologic time?
Precambrian Time extends from 4.6 billion years ago to 540million years ago. that's the greatest expanse of geologic time.
What do the relative geologic time and absolute geologic time combine to form?
The geologic time scale.
Diffrenciate geologic time with geologic column?
Geologic column is an ordered arrangement of rock layers that is based on the relative age of the rocks. Geologic time is the time IN the geologic column.

What is an era in geologic time?
an era is a very long span of geologic time
How do humans relate to geologic time scale?
in the scope of geologic time, how significant is the presence of humans?
What does geologic time have to do with eras?
Eras are subdivisions of larger units of geologic time called eons.
What do you called the scale of time that records the events about the history of the earth?
Geologic Time. It's called the Geologic Time Scale.
What is the shortest piece of geologic time?

88 percent of geologic time is represented by the Precambrian time span.
Is A geologic era is a shorter unit of time than a geologic period?
n

The units of geologic time are much longer
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.
