Question

describe the primary economic activity for each of the three colonial regions:the New england colonies,the middle colonies, and the southern colonies explain how the geography of each region helped determine its economy

Answer 1

The New England Colonies looked to their natural resources as a way to make a living; the environment forced them to look for other ways to make a living other than farming. 

The Southern Colonies didn't develop all their natural resources as a way to make a living; there was excellent soil for farming income, so there was no need to develop natural resources for manufacturing.
 
The differences in manufacturing occurred between the Southern Colonies and the New England Colonies:

The Southern Colonies developed their main natural resource, their farmland, and not much manufacturing; the opposite occurred in New England.

Answer 2

Answer:

The climate and geography of the New England colonies had short farming seasons and long and cold winters, with rocky lands and forests. Since the small farms could only provide food and support a family, economy was based on hunting in the forests and fishing. Thus, the primary economic activities were lumbering, fishing, whaling, fur trading and ship building.

The Middle colonies had longer farming seasons and very fertile land, which allowed them to grow grain and livestock.Besides, the colonies were near lakes, rivers and the Atlantic ocean, so they sometimes traded raw materials for manufactured goods.

Finally, the Southern colonie's weather was warm and sunny, with coastal plains and forests, which permitted large tobacco, rice and corn plantations.
