Final answer:
The Fall Line in Georgia represents an important factor as it was an important source of power due to a change in elevation, which allowed for the harnessing of energy to power mills and factories.
Step-by-step explanation:
The 'Fall Line' in Georgia history represents an important factor because it was an important source of power due to a change in elevation. The line of the highest points in North America marks the separation between rivers flowing eastward and westward, creating a change in elevation that creates potential energy.
This potential energy can be harnessed to power mills and factories, making the Fall Line a significant economic and industrial location in Georgia history.
