Are epochs part of periods?
Yes, epochs are subdivisions of periods in the geological time scale. Periods are further divided into epochs based on distinct changes in Earth's history, such as significant shifts in climate or the emergence of new species.
How are eras and periods of the geologic time scale named?
Eras and periods on the geologic time scale are often named based on significant geological events, key fossil groups, or regional stratigraphy that characterize that time interval. For example, the Triassic Period is named after the three distinct rock layers found in Germany. The Cretaceous Period is named after the Latin word "creta," meaning chalk, due to the abundant chalk deposits from this time.
What determines the divisions of eras and periods on the geological time 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.
Why are the time periods of the paleozoic and mesozoic subdivided into early middle and late instead of named epochs as they are in Cenozoic?
The time periods of the Paleozoic and Mesozoic are subdivided into early middle and late instead of named epochs as they are in Cenozoic periods is due to the basis of the occurrence of particular fossils. It is also based upon the absence or appearance of geological horizons.
What are subdivisions of a geological eras?
Subdivisions of geological eras include periods, epochs, and ages. These subdivisions are used to further categorize and study the complexities of Earth's history and the events that have shaped it over time. Each subdivision represents a distinct span of geological time with its own unique characteristics and defining features.
