Answer:
It gave the North a military advantage
Step-by-step explanation:
Thanks to the number of factories in the North, the Union could easily produce the weapons and ammunition needed for their military. The South, on the other hand, struggled with this due to their lack of factories. At this time, the South's economy relied on the production of cash crops like cotton and tobacco. This is why the South was forced to trade with countries like Great Britain and France in order to get the materials they needed.
