Historical geologists initially used relative dating for rock layer organization but later applied absolute dating techniques, like radioactivity, for precise dating.

It highlights significant geological transformations, the emergence of life through simple organisms like cyanobacteria that enriched the atmosphere with oxygen, and the resultant formation of the ozone layer.
