geological time chart

A geological time chart is a timeline that outlines the history of Earth, spanning billions of years. It divides this vast period into different segments, including eons, eras, periods, and epochs, each characterized by significant geological and biological events, such as the formation of mountains, the rise and fall of species, and mass extinctions. This chart helps scientists and the public understand the sequence of life and geological changes on our planet, illustrating how long processes like evolution and continental drift occur over time, and providing context for the current state of Earth.
