What does one Ma on the geological time scale represent?
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.
What is a geological unit?
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.
What does the geological term ka mean?
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.

WHAT IS THE The geological era about which we have the least information called?
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.
What is a geological unit?

Which sequence of geological time represents increasing lengths of time?
The sequence of geological time that represents increasing lengths of time is: epoch, period, era, and eon. An epoch is the smallest unit, followed by a period, then an era, and finally an eon, which encompasses the longest spans of geological time. Each successive category includes multiple subdivisions of the previous one, reflecting a broader timeframe.
What era is divided into smaller unit time scale?
The era that is divided into smaller units of time scale is the "Geological Era." Geological eras are major subdivisions of geological time and are further divided into periods, epochs, and ages, allowing scientists to study Earth's history in more detail. The three primary geological eras are the Paleozoic, Mesozoic, and Cenozoic, each encompassing significant events in the planet's evolutionary history.
What does the geological term Ga mean?
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
What is geological scale?

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.
