Which geographic feature contributed most directly to the development of factories in the Northeast United States?

Thin, rocky soil

because they didn’t have rich soil and long growing seasons like the south, northerners colonists had to find another way to prosper

they turned to manufacturing to make their living

Do you have more info about it ? i doubt this is the answer because i don't have all the information but if trouble was brewing in a clinic maybe it was an argument as to which clinic was better or smth of that nature
