Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. [1] Historical geology examines the vastness of geologic time, measured in billions of years, and investigates changes in the Earth , gradual and sudden, over this deep time .

The history of the Earth can be organized chronologically according to the geologic time scale, which is split into intervals based on stratigraphic analysis. [2] [21] The following five timelines show the geologic time scale to scale. The first shows the entire time from the formation of the Earth to the present, but this gives little space ...
The geological history of North America comprises the history of geological occurrences and emergence of life in North America during the interval of time spanning from the formation of the Earth through to the emergence of humanity and the start of prehistory.
After the Huronian glaciation came to an end, the Earth entered a long period of geological and climatic stability known as the Boring Billion. However, this long period was noticeably euxinic , meaning oxygen was scarce and the ocean and atmosphere were significantly sulfidic , and that evolution then was likely comparatively slow and quite ...
