relative dating
The dating process that places geologic events in proper sequence is called relative dating. Relative dating relies on the principles of superposition, original horizontality, cross-cutting relationships, and faunal succession to determine the relative ages of rock layers and fossils. It does not provide an exact age in years but helps establish a chronological order of events. Absolute dating techniques, such as radiometric dating, are used to determine the actual numerical age of a rock or fossil.
An example of a sudden geologic process is a volcanic eruption. These events can release massive amounts of lava, ash, and gases in a short period, causing rapid changes to the landscape and environment.
Geologists construct the geologic column by analyzing the layers of rock exposed in different locations and correlating them based on their lithology, fossils, and relative ages. This process involves identifying key rock layers and their characteristic features to determine the sequence of geological events over time. The geologic column is a visual representation of Earth's history, with the oldest rocks at the bottom and the youngest at the top.
The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.

sequence of events...
That sequence of events involving the character and central conflict is typically referred to as the plot. It is the series of events that make up the storyline of the narrative and drive the story forward.
I think you mean chronological order or sequencing.
Events typically occur in a chronological order, one after the other, in a sequence. Each event leads to the next, creating a cause-and-effect relationship. Maintaining the sequence of events is crucial for understanding the progression of a story or process.

You call them 'sequence of events'.

Geologic events are recorded using relative dating techniques such as stratigraphy, which involves studying the layering of rocks to determine the sequence of events. Other methods include comparing the fossil content of different layers or using principles like the law of superposition to establish the relative timing of events. These techniques help geologists establish the chronological order of events without assigning specific numerical dates.
Constructing a geologic column is useful in Earth science because it provides a visual representation of the Earth's history and the sequence of events that have occurred over time. It helps scientists understand the relative ages of rocks and fossils, as well as the processes that have shaped the Earth's surface. By studying the geologic column, researchers can reconstruct past environments, track geological changes, and make predictions about future events.
