Geologists designate different time periods in Earth's ancient past using the geologic time scale, which is divided into eons, eras, periods, epochs, and ages. These divisions are based on significant events in Earth's history, such as mass extinctions, major geological or biological changes, or the appearance of key fossils. The boundaries between these time periods are defined by specific markers in the rock record, such as changes in fossil assemblages or shifts in sedimentation patterns. Geologists use a combination of stratigraphy, radiometric dating, and fossil evidence to accurately assign ages to these time periods.
What else can I help you with?
Why do geologists and biologists refer to the same time scale when describing events in earth's ancient history?
Because these time periods had been pre recorded down before as soid proof to support that these events during the time periods had actually happened, this is why they both use them, its basically the international time scale used. Scienece homework? lol

How are geological time periods divided and classified in the field of geology?
Geological time periods are divided and classified based on the rock layers and fossils found in them. Geologists use specific criteria to determine the boundaries between different periods, such as changes in rock types, fossil assemblages, and major geological events. These periods are then grouped into larger units called eras and eons, providing a framework for understanding Earth's history.
