The two true statements about the Fall Line are:
- It makes the northern edge of the Piedmont Region.
- Many cities have developed along it.
The Fall Line is known for being a significant geographic boundary where rivers descend from the harder rock of the Piedmont to the softer sediments of the Coastal Plain, creating waterfalls and rapids. This has historically led to the development of cities and industrial sites along the Fall Line due to the availability of water power.
