The geologic column was created by globally correlating small columns and filling in the gaps. No single location records all of Earth's history, but by piecing together information from multiple locations and using relative dating techniques, scientists were able to create a general timeline of Earth's history. This involved identifying and correlating rock layers of similar age from different locations and using fossils and other markers to determine the relative ages of those layers. The resulting geologic column is a composite of information from many different locations and provides a framework for understanding the sequence of events in Earth's history.
