The smallest unit of geologic time is a "stage," which is typically defined by specific rock layers or fossils that mark distinct intervals of time within a geological period. Stages are further divided into ages, which correspond to even smaller intervals of time.

What are the two basic units of the geologic time scale?
The two basic units of the geologic time scale are eons and eras. Eons are the largest units of time, while eras represent subdivisions within eons.
What is the next smaller division of geologic time after era?
The next smaller division of geologic time after era is period. Periods are further divided into smaller units called epochs.
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.
From smallest to largest geologic time is divided into?
Geologic time is divided into eons, eras, periods, epochs, and ages. These divisions help scientists organize and study the Earth's history over billions of years.
How is geologic history divided?
Geologic history is divided into four main eons: Hadean, Archean, Proterozoic, and Phanerozoic. These eons are further divided into eras, periods, and epochs based on significant events and changes in Earth's geology and life forms. Each division represents a distinct time period characterized by specific geologic or biological features.
What is the smallest unit of time on the geologic time scale?
The smallest unit of time on the geologic time scale is an epoch, which typically lasts millions of years. It is used to divide periods into smaller segments based on significant changes in Earth's history.
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.
What are the basic unit of the geological time scale?
The smallest unit of geologic time is an age, followed by epoch, period, era, eon, and super eon.
What is the smallest division of geologic what time?
epoch
Which is the smallest division of time on the geologic scale?
Epoch
What is the major unit of geologic time?
Era
What are the two basic units of the geologic time scale?
The two basic units of the geologic time scale are eons and eras. Eons are the largest units of time, while eras represent subdivisions within eons.
Which geologic time unit includes the largest amount of time?
Eon.
A unit of geologic time that includes two or more periods?
Era
What is the shortest piece of geologic time?
The shortest recognized unit of geologic time is a "millisecond" which is one thousandth of a second. Geologic time is typically measured in much larger units like millions of years.
What is the next smaller division of geologic time after era?
The next smaller division of geologic time after era is period. Periods are further divided into smaller units called epochs.
What unit of measurement would a geologist use for time?
Geologists measure geologic time in years.
