Answer:
Crops and farming
Step-by-step explanation:
Agriculture was one of the main ways the people of both the North and the South were able to sustain themselves. Although the climates differed slightly and the colonists of both areas had different ways of doing things, cash crops powered their economy. While the Southern colonies were full of large plantations that required the use of slave labor, smaller and self-suffucient tobacco farms were grown in the North where agriculture was supported (meaning where it wasn't too cold and where the soil wasn't hard/rocky).
