The Geological Evolution of the Earth
This document presents in a vertical time line images of the Earth's geologic evolution from 510 million years ago to the present -- roughly the last 10% of the Earth's existence. The crust has already solidified and the atmosphere has accumulated oxygen from 300 million years of algal growth in the Earth's vast oceans.
