North america Geographic History

Early North america history was affected by the fact that the once the mega continent spread out, it  caused  the continent to separate into drifting islands. North america was affected by The Great Ice Age, which caused the glaciers over North America to diminish. Because of this , the North american continent was far away from Europe and Asia; therefore, a land bridge emerged linking Asia and North America together by the Bering Sea. The Bering Strait allowed for early people to migrate to the region.
