The Earth is 4.6 billion years old, and over this time, its complexion has changed dramatically. Geoscientists use remnant information from ancient rocks and sedimentary deposits to unravel the history of the planet. What were the heights of ancient mountains? What events created the stratigraphy seen underneath hillsides or within buried river valleys? What kinds of storms impacted shorelines and oceans? Hutton (1785) and others convinced us that the present is the key to the past, arguing that sediments accumulating in the sea (ie, the sedimentary sink) eventually become the land upon which we live (the source):“As it is not in human record, but in natural history, that we are to look for the means of ascertaining what has already been, it is here proposed to examine the appearances of the earth, in order to be informed of operations which have been transacted in time past. It is thus that, from principles of natural philosophy, we may arrive at some knowledge of order and system in the economy of this globe, and may form a rational opinion with regard to the course of nature, or to events which are in time to happen.”
