What are the major time intervals represented by the geologic time scale?
The Geologic Time Scale is divided up by four major intervals. In order from Largest to smallest: Eons are the largest time frame covering hundreds of millions of years. Eons are divided into smaller time intervals known as Eras. Eras are subdivided into Periods. Periods are broken into finer subdivisions known as Epochs.

What is a measurements of earth's history divided into time periods?
fossil record geologic time scale
What subdivisions make up the geologic time scale?
The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them. As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.
How are eras and periods of the geologic time scale named?

How is geologic time scale organized?
By eons, eras, epochs, and periods.
Which time scale divided the history of the earth into eras periods and epochs?
The geological time scale is the history of the earth. This is in the eras period and epochs.
What units divide the geologic scale?
The units that divide the geologic time scale are Eons, Eras, Periods, and Epochs. Eons are the biggest, Eras are the second biggest and so on and so forth. So it goes Eons, Eras, Periods, and then Epochs. I know this because i just took a test on it in science so i know its right.
Are epochs part of periods?
Periods are subdivided into periods of time know as epochs.

How were the periods divided in the geological time scale?
The longest periods of the geological time scale are eons. Each eon is divided into eras and each era is made up of periods, which are further divided into epochs. Each division ended when a significant geological event occurred, such as a major ice age ending or a meteor impact resulting in a mass extinction of animal life, etc.

What is the geological time scale?
The geologic time scale is the system of chronology that organizes the Earth's history based on stratigraphy, or the study of Earth's rock layers and their ages. The geologic time scale is divided into several spans of time. From longest to shortest they are: Eons, eras, periods, epochs, and ages.
