The geological time scale is a system of chronological dating used by geologists and paleontologists to describe the timing and relationships between events that have occurred throughout Earth's history. It is divided into eons, eras, periods, epochs, and ages, each representing significant intervals of time marked by important geological or biological events. The time scale provides a framework for understanding the history of the Earth and the evolution of life.
One million years on the geological time scale represents one million years of Earth's history. It is a unit of time used to measure and discuss long-term geological events and processes.

The geologic time scale is a system that organizes Earth's history into distinct intervals based on changes in the rock record. It helps geologists understand the sequence of events in Earth's history, the evolution of life, and the timing of major geological events such as mountain building and climate change. By providing a framework for dating rocks and events, the geologic time scale is essential for interpreting Earth's past and predicting future geological processes.
Some shortcomings of the geological time scale include the incomplete nature of the rock record, which may result in gaps or missing information. It can also be challenging to accurately date certain rock layers or events, leading to uncertainties in assigning precise ages to specific time intervals. Additionally, the geological time scale is constantly being refined as new data and techniques become available, so it is subject to revision.
The largest divisions of time on the geological time scale are eons, which are the longest units of time and are further divided into eras. The current eon, the Phanerozoic Eon, is divided into three eras: Paleozoic, Mesozoic, and Cenozoic. Each era is further subdivided into periods, epochs, and ages.
The geological time scale organizes a long period of time.

A geological time scale is best reconstructed using a combination of radiometric dating, fossil evidence, and stratigraphic relationships between rock layers. By utilizing these methods together, scientists can create a comprehensive and accurate timeline of Earth's geological history.
One million years on the geological time scale represents one million years of Earth's history. It is a unit of time used to measure and discuss long-term geological events and processes.
