Question

The map shows an island arc in Alaska named the Aleutian Arc. What does the arc suggest about its surrounding geographic region?
A. The region lies on a transform boundary.
B. The region is affected by a subduction zone.
C. The region has a hot and humid climate.
D. The region might have active volcanos
E. The region is close to the convergent boundary.

Answer 1

The answer is B.

Reason:

The Aleutian Arc volcanism is the result of the active subduction of the Pacific Plate beneath the North American Plate.

Answer 2

Answer: Hello!

The region is affected by a subduction zone, the region may have active volcanoes, and that the region is close to a convergent boundary. From the map it can be seen that the region is close to the continents, therefore, it is possible that there is the boundary of tectonic plates surrounding it. One can also see the presence of islands, thus, it is quite possible that there lies a subduction zone close to them. This also demonstrates that the boundary is convergent, as transform boundaries do not result in elevation. Close to the convergent boundaries, one can witness recurrent volcanoes and shallow earthquakes.
