What word represents the broadest division on a geologic time scale?
Eon is the broadest division on the geologic time scale, representing the longest time span. Eons are further divided into eras, which are then subdivided into periods, epochs, and ages.
Is A geologic era is a shorter unit of time than a geologic period?
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.
How would you rewrite the following sentence to make it true Geologic subdivide periods into eras?
To make the sentence true, it can be rewritten as: "Geologic eras are subdivided into periods." This accurately reflects the hierarchical structure of geological time, where eras are larger divisions that contain multiple periods.
In the divisions of the geologic time scale the largest units are eons which are divided into eras. Eras are then divided into .?
Eras are then divided into periods. Each period represents a significant span of geological time characterized by distinct geological and biological events. Periods can be further subdivided into epochs and ages, providing a more detailed framework for understanding Earth's history.
What list places the divisions of the geologic time scale in order from longest to shortest?
The order of geologic time from smallest to largest is Phanerozoic, Proterozoic, Archean and Hadean (Deep Time). These four periods are called Eons which can be further subdivided into Eras, Periods and Epochs. Most people are more familiar with the periods such as Cambrian, Permian, Triassic, Jurassic and. Cretaceous and many more to numerous to mention. To learn more, Google geologic time scale.
What is a long span of geologic time called?
A long span of geologic time is called an era. This is a major division of geologic time that is further subdivided into periods. Examples of eras include the Paleozoic, Mesozoic, and Cenozoic.
Eras of geologic time are subdivided into?
Eras of geologic time are subdivided into periods, which are further subdivided into epochs. These divisions help geologists categorize and study Earth's history and the changes that have occurred over millions of years. Each subdivision represents a distinct period of time with unique geologic events and characteristics.

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.
What is an era in geologic time?
an era is a very long span of geologic time

What are the major time intervals represented by 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.
How many years are in an eon?
An eon is the longest geologic time period, typically lasting billions of years. It is subdivided into eras, which are further divided into periods, epochs, and ages.
What time periods fit the concept of geologic time?
Geologic time consists of eons, eras, periods, epochs, and ages. These measure periods of billions or millions of years.
The largerest division of time on the geologic time scale is?
The largest division of time on the geologic time scale is an eon. Eons are subdivided into eras, which are further divided into periods, epochs, and ages. The current eon, the Phanerozoic, began around 541 million years ago and is divided into the Paleozoic, Mesozoic, and Cenozoic eras.
What division of geologic time is smaller than an era?
A period is smaller than an era in the geologic time scale. It is further subdivided into epochs and ages.
How many geologic time periods did the dinosaurs live?
The Dinosaurs lived in 3 Geologic time periods-The Triassic, Jurassic, and Cretaceous. These 3 time periods where the three periods of the Mesozoic Era, which is also known as the Age of Reptiles.
