Answer:
The geologic record is the history of Earth as recorded in the rocks that make up its crust. Rocks have been forming and wearing away since Earth first started to form, creating sediment that accumulates in layers of rock called strata.
The geologic record in stratigraphy, paleontology and other natural sciences refers to the entirety of the layers of rock strata deposits laid down by volcanism or by deposition of sediment derived.
