Final answer:
The economies of the northern and southern colonies in the early 1700s had distinct differences in terms of crops produced and reliance on slave labor.
Step-by-step explanation:
In the early 1700s, the economies of the northern and southern colonies in America had several main differences. In the New England colonies, farmers focused on self-sufficiency and engaged in whaling, fishing, and shipbuilding for the export market. The middle colonies grew grains, vegetables, and raised livestock, while also leading in iron manufacturing. The Chesapeake colonies primarily focused on tobacco production, but also grew other crops to offset bad tobacco harvests. The southern colonies exported goods like rice, indigo, and salt pork, relying heavily on slave labor.
