I think you are going for plate tectonics.
There are technically more than three traits and those traits are distinctive, widespread, abundant and limited in geologic time.
There are four eons dividing the geologic scale. Three occurred during the Precambrian era.
No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
Geologic units of similar ages are typically shown on a geologic map using the same color or pattern to represent them. This helps to visually differentiate between different units and understand their distribution across a region. Stratigraphic relationships and relative ages may also be indicated to show how these units are connected in terms of geologic time.
uniformitarianism
The geologic principle that the same geologic processes that operate today operated in the past to change Earth's surface.

Ideas has three syllables.
Divergent
because new ideas are ideas that change they change the world because they do
It all happens suddenly
this question is not complete - what three of WHAT ideas - ideas not listed
These 3 things usually happen to signal a change from one geologic time interval to another...rocks changeclimate changesdisappearances or appearances of life
The event used to separate geologic eras is a significant change in Earth's environment or life forms, known as a mass extinction event.
The idea that geologic change can happen suddenly is known as catastrophism. This theory proposes that Earth's geological features are mainly a result of sudden, short-lived, and violent events, rather than gradual processes over time. While some catastrophic events like earthquakes and volcanic eruptions can cause rapid geologic changes, most changes on Earth's surface are the result of slow and continuous processes such as erosion and sedimentation.
