"The Geological Timescale"

The Geological Timescale is a chronological framework that divides Earth's 4.6-billion-year history into manageable segments based on significant events and changes in Earth's crust, fossil records, and climate. It includes eons, eras, periods, epochs, and ages, helping scientists organize and understand Earth's development, such as the appearance and extinction of different life forms. This timeline allows us to trace the evolution of Earth's surface, atmosphere, and life, providing context for geological and biological processes over vast time spans.
