Question

The "fall line" exists where rivers cross a geologic "cliff" where coastal plains meet higher-altitude uplands. Fall lines are typically characterized by rough river rapids and waterfalls. As such, early travelers were required to portage the river at the fall line. This required costly unloading and re-loading of one’s cargo on either side of the line. Small settlements often formed along fall lines to support the portage and minimize transportation costs.

- Use the transportation cost model discussed in class to explain the formation of settlements along the fall line.

- Modern travelers no longer need to portage waterfalls and rapids. We use bridges. So, why might it be that population density *today* still clusters along the fall line?

Expert Solution

Step 1

Dear Subscriber! Since there is no detail included in the question about the transportation cost model studied in class, we have taken the conventional model for transport costs and logistics as the basis for this answer. If you meant any other model, you can repost the question by including the details, for us to address it accordingly. Thank you.

1) use transportation cost model to explain the formation of settlements along the fall line

2) to explain why population density in modern times still clusters around fall lines in spite of there being bridges to portage waterfalls and rapids
