Step-by-step explanation:
In the colonies of New England and the southern region from 1607-1754, one key difference in their economies was that New England had a diversified economy, while the South relied primarily on cash crops.
In New England, the long winters and rocky soil made agriculture difficult, so they focused on other industries such as whaling, fishing, and shipbuilding for the export market. They also engaged in manufacturing and iron production.
In the southern colonies, particularly the Chesapeake colonies, tobacco production was the main focus, but they also grew other crops and engaged in other industries like naval stores and deerskin trade. They also exported goods like rice, indigo, and salt pork to the Caribbean colonies in exchange for slaves.
