What does the geological time scale represent?

The geological time scale serves as a comprehensive framework that organizes the history of Earth into distinct intervals, making it easier to understand the evolution of our planet and the life forms that have inhabited it over billions of years. It is divided into various segments, including eons, eras, periods, epochs, and ages, which reflect significant geological and paleontological events. This scale encompasses everything from the formation of Earth, the emergence of life, major extinction events, and significant geological transformations like continental drift and climate changes. Thus, it captures a vast array of Earth's history, including rock formations, fossil records, and changes in the Earth’s environment over time.
