Geological Timeline

The geological timeline is a way scientists organize Earth's history into vast periods based on significant events, like the appearance of life, major climate changes, and mass extinctions. It spans billions of years, starting from Earth's formation about 4.6 billion years ago to the present. The timeline is divided into eons, eras, periods, epochs, and ages, helping us understand how the planet has evolved over time. Fossil records, rock layers, and radiometric dating are used to piece together this history, revealing the dynamic processes that shaped the Earth's surface and its diverse life forms throughout Earth's history.
