Step-by-step explanation:
The coastal city of Baltimore is a vital spot for trade and industry.
Being located on the Chesapeake Bay, Baltimore has good port facilities that make it a break of bulk point, where cargo is unloaded and reloaded for different modes of transportation. This attracts industries and leads to the growth of the city.
Additionally, Baltimore has a history of shipbuilding and maritime trade, with black-owned businesses such as the Chesapeake Marine Railway and Dry Dock Company playing a significant role in the city's economy in the immediate aftermath of the Civil War.
