Question

What statement correctly describes the fall line?

a) The fall line is where hilly terrain meets higher elevation terrain.
b) The fall line separates the blue ridge region from the piedmont.
c) Above (north of) the fall line, most of the rivers are deeper and wider, allowing navigation.
d) The fall line marks sharp elevation changes creating rapids and waterfalls on Georgia’s rivers.

Answer 1

The fall line marks where rivers create rapids and waterfalls as they descend sharply from higher elevation regions like the Piedmont to the lower coastal plain. The correct option is d.

Step-by-step explanation:

The correct statement that describes the fall line is: The fall line marks sharp elevation changes creating rapids and waterfalls on Georgia’s rivers. This phenomenon occurs at the boundary where the hilly or mountainous regions of the inland Piedmont plateau meet the flat coastal plain.

At the fall line, rivers drop abruptly, which historically provided water power for mills and factories and led to the rise of cities, but it also marks the head of navigation for rivers, due to obstacles like rapids and waterfalls impeding further travel upstream.

Hence, Option d is correct.
