Answer:
In the southern colonies, economic activity was primarily centered in the plantation areas, where crops such as tobacco, rice, and indigo were grown for export. These crops were grown on large plantations, which were often worked by enslaved Africans. The plantation economy was the dominant economic system in the southern colonies, and it shaped the social, political, and cultural development of the region.
The plantation economy was centered in Virginia, Maryland, and the Carolinas, but it also extended into Georgia and parts of Florida. The major port cities in the southern colonies, such as Charleston, Savannah, and New Orleans, were also important centers of trade and commerce, as they served as the primary points of entry for the export of plantation crops and the import of European goods.
In addition to the plantation economy, the southern colonies also had small-scale agriculture and trade in local markets. Some areas, such as the Appalachian Mountains, were more focused on self-sufficient farming and trade in local markets, rather than large-scale export crops.
