It is the province in the east central Canada that borders the u.s
Leaders are greedy for more power and land, a large population requires more food, neighbors are becoming to strong
Glaciers shaped the landscape is the answer. Actually, in Nova Scotia near Halifax there is a glacial boulder or erratic of basalt which is deemed to come from about 130km away perhaps from the north or NW. Also, there are glacial striations there on the bedrock which can be used to determine the sense of the direction of flow of the ice. In New England, there are pro-glacial lakes. Both the Maritimes and New England were most likely covered by the Laurentide continental glaciation.
The minimum amount of states is 11, those states being California, Texas,Florida,Pennslyvania, Illinois, Ohio,Michigan, New jersey, Georgia, And North Carolina. Hope this helps!
