epoch
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.
Epoch
The shortest division in the geologic time scale is an Epoch. Epochs are subdivisions of a period and are typically tens of millions of years long.
The correct order representing units of geologic time in increasing order is B. Eon, era, period, epoch. This hierarchy reflects the largest to smallest divisions of geologic time, with eons being the longest intervals and epochs being the shortest.
The order of units of geologic time from longest to shortest is: eon, era, period, epoch.
We are living in the Holocene Epoch of the Quaternary Period in the Cenozoic Era of geologic time.
After an era, the next smallest division of time would be an epoch. An epoch is equal to around 10,000,000 years, where as an era is 100,000,000 years.
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.
We are living in the Holocene Epoch of the Quaternary Period in the Cenozoic Era of geologic time.
A period is smaller than an era in the geologic time scale. It is further subdivided into epochs and ages.
The shortest piece of Geologic time is the Holocene Epoch in the Cenozoic Era>
