What is a key characteristic of the Fall Line's geographic feature?

The Fall Line is a significant geographic feature in Georgia, noted for marking the point where rivers flowing from the higher land of the Piedmont plateau descend to the lower coastal plain. This descent creates a series of waterfalls and rapids, which are prominent in this area. The presence of waterfalls, which impede navigation along the rivers, historically played a vital role in the development of settlements and industries along the Fall Line.

This characteristic has shaped not only the landscape but also the economic and cultural growth of the regions surrounding it, as the waterfalls served as potential sources of hydropower and locations for mills. Thus, the defining feature of the Fall Line's geography is its waterfalls, making it a critical point of interest in understanding both the physical geography and the historical development of Georgia.
