A gap in the geologic time scale refers to a period during which there is a lack of rock layers or fossil evidence, making it difficult to understand the geological or biological history of that time. These gaps, also known as unconformities, can occur due to erosion, non-deposition, or tectonic activity. They highlight intervals where significant geological events may have occurred, but the evidence has been lost or remains undiscovered. Such gaps can complicate the reconstruction of Earth's history and the evolution of life.
Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.
Phanerozoic is the eon which geologic time scale means visable life.
Eon is the broadest division on the geologic time scale, representing the longest time span. Eons are further divided into eras, which are then subdivided into periods, epochs, and ages.
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.

Geologic Time. It's called the Geologic Time Scale.

in the scope of geologic time, how significant is the presence of humans?
The Precambrian
Cenozoic
On a geologic time scale, yes. On any other time scale, no.
Eon The largest expanse of time on the geologic time scale is the eon. An eon would encompass at least two eras.
