Information on time periods in earth's history and the events that happened in those time periods, all based on the study of fossils and rock layers.
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
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.
Scientists first developed the geologic time scale by studying rock layers and index fossils worldwide. With this info. (information if you forget!), scientists placed Earth's rocks in order by the relative age.

The geologic time scale.
Geologic Time. It's called the Geologic Time Scale.

Phanerozoic is the eon which geologic time scale means visable life.
The Precambrian
in the scope of geologic time, how significant is the presence of humans?
Cenozoic
On a geologic time scale, yes. On any other time scale, no.
The geologic time scale provides a timeline of Earth's history, dividing it into periods based on significant events and changes in the planet's environment. The major divisions of geological time are eons, eras, periods, epochs, and ages, each reflecting different intervals of time with distinct characteristics and geological events.
Eon The largest expanse of time on the geologic time scale is the eon. An eon would encompass at least two eras.
