It is an epoch.
One million years on the geological time scale represents one million years of Earth's history. It is a unit of time used to measure and discuss long-term geological events and processes.
A geological unit is an identifiable - "mappable" volume or layer of rock where the relative age can be determined. The link below gives more detail.
The geological term "ka" stands for "kiloannum," which is a unit of time equal to 1,000 years. It is often used in geology and archaeology to describe dates and time intervals in the context of Earth's history, such as the age of geological formations or the timing of significant events. For example, a date expressed as "100 ka" would refer to 100,000 years ago.

Geological time is typically divided into units based on types of rock layers, fossils, and major events in Earth's history. The primary units of geological time are eons, eras, periods, epochs, and ages. These divisions help scientists organize and study the Earth's long history.
Eons
The smallest unit of geologic time is an age, followed by epoch, period, era, eon, and super eon.
One million years on the geological time scale represents one million years of Earth's history. It is a unit of time used to measure and discuss long-term geological events and processes.

The Precambrian is the geological era about which we have the least information, as it covers an extensive period of time from the formation of the Earth to the beginning of the Paleozoic era, and much of the evidence from this era has been altered or eroded over time.

The geological time scale organizes a long period of time.
It means years x 10 to the power of 9. It is the unit that the age of of the earth is measured in. It stands for Giga Anum Giga = 10^9 and Anum = 1 year
The measurement of Earth's history divided into time periods is called the geological time scale. It is divided into eons, eras, periods, epochs, and ages, with each unit representing a significant change in Earth's geological and biological history.
No, I don't think so at least I've never heard of it.
IT encompasses all of the geological time period that have happened since the begin of time
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.
