The Geological Time Scale (book)

"The Geologic Time Scale" is a book that organizes Earth's history into a chronological framework based on geological, fossil, and climatic data. It divides Earth's 4.6-billion-year history into hierarchies like Eons, Eras, Periods, and Epochs, helping us understand when major events—such as the appearance of life, mass extinctions, and the rise of different species—occurred. The book offers detailed explanations of these intervals, illustrating how Earth's surface and life have changed over millions and billions of years, providing a comprehensive timeline that contextualizes the planet's geological and biological evolution.
