I think you are going for plate tectonics.
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.
The shortest piece of Geologic time is the Holocene Epoch in the Cenozoic Era>
The three primary geologic forces that constantly change the Earth's surface are tectonic activity, erosion, and weathering. Tectonic activity involves the movement of Earth's plates, leading to earthquakes, volcanic eruptions, and the formation of mountains. Erosion, driven by wind, water, and ice, wears down rocks and transports sediments, while weathering breaks down rocks into smaller particles through physical, chemical, and biological processes. Together, these forces shape landscapes and contribute to the dynamic nature of the Earth's surface.
These 3 things usually happen to signal a change from one geologic time interval to another...rocks changeclimate changesdisappearances or appearances of life
uniformitarianism
The geologic principle that the same geologic processes that operate today operated in the past to change Earth's surface.
uniformitarianism
because new ideas are ideas that change they change the world because they do
It all happens suddenly
Well i think i may be a werewolf so i have a few ideas..... 1 you will tend to stare at the moon. 2 you will crave meat.3 you might change at moments when you are angry. That is all my ideas.
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.

True? xD
The 3 main ideas are, 1. The rock record provides evidence of geologic events and forms of the past. 2. Processes observed on Earth in the present also acted in the past. and 3. Earth is very old and has changed over geologic time.
