Final answer:
Cities were built on the fall line for several reasons, including the hydroelectric potential, break-in bulk points for river navigation, and excellent farmland.
Step-by-step explanation:
Cities were built on the fall line for several reasons:
- Hydroelectric Potential: Waterfalls on the fall line provided a key source of power for industry, attracting workers and encouraging manufacturing.
- Break-in Bulk Points: Cities formed on the fall line because it served as a break-in bulk point for river navigation. This allowed for efficient transportation of heavy cargo over long distances.
- Excellent Farmland: River soil on the fall line provided excellent farmland, leading to urban growth and increased agricultural productivity.
