The geologic column is a composite stratigraphic column that represents the relative sequence of geological events and is created by correlating strata from millions of locations around the world. It is not the complete record of Earth's history preserved in the rocks at any given location (A), nor is it a portrayal of the spatial distribution of rock units at the Earth's surface (B). It also does not refer to a specific interval of strata composed of a particular rock type or group of rock types (D).
