To help them interpret rock sequence .
Geologic column is an ordered arrangement of rock layers that is based on the relative age of the rocks. Geologic time is the time IN the geologic column.

Geologists use the geologic column to classify layers of rocks and fossils that make up the Earth's crust.
they serve as good geologic time markers
Slow geologic processes and catastrophic events
the geologic column is used for identifying the layers in a rock sequence.
Geologic time refers to the vast expanse of time over which Earth's history is recorded, characterized by different eons, eras, periods, and epochs. The geologic column, on the other hand, is a hypothetical representation of the Earth's rock layers and the fossils they contain, arranged in chronological order based on relative dating principles. Geologic time provides the framework for understanding the sequence of events in Earth's history, while the geologic column is a visual representation of this history based on the rock layers and fossils found in stratigraphic succession.
Geologists measure geologic time in years.
They will normally be located at the bottom, unless otherwise upset through geologic activity.
The geologic column is the result of the core sample showing layers of artifacts and material. Since some of these can be carbon dated, a relative time period can be established.
