Question

What is a Fall line? What is it's use/uses?

Answer 1

Answer:

The fall line is the point at which boats traveling upriver usually cannot continue any further. It is also the point at which hydroelectric power generation may be possible, taking advantage of the energy of the waterfalls.

Rivers were generally navigable below the fall line so towns and cities were established for trade at the point at which a river could be used to transport goods.

Answer 2

Answer:

A fall line is the imaginary line between two parallel rivers, at the point where rivers plunge, or fall, at roughly the same elevation. Fall lines are often located where different elevation regions, such as coastal and piedmont, meet. They are important to people and businesses.
