Areas settled by Northeastern American Indians had which of the following geographic features? the Appalachian Mountains and a coastal plain

A. the Appalachian mountains and a coastal plain

Explanation:
The northeast cultural areas extend to the provinces of the Quebec in Canada and the Ohio river valleys, and then down to the North Carolina coasts, thus are dominated by the Appalachian mountain and the presence of the hill and the predominant peaks.
Living east of the Mississippi River, and the great lakes in the north and the Tennessee River in the south. Earlier this region was known as the woodland border and thus considered a distinct cultural region due to the larger concentration of tribes.
These were a few hundred people that lived close to the tribes and the croplands.

That is an example of an idiom.

I hoped this helped.
