The map shows the location of active volcanoes between the Pacific Ocean and the Bering Sea. What do these volcanoes indicate about plate tectonics in the region?
Understand the Problem
The question is asking about the geological significance of the active volcanoes located between the Pacific Ocean and the Bering Sea, particularly in relation to plate tectonics in that region.
Answer
Convergent plate boundary indicated by island arc.
The volcanoes form an island arc, indicating a convergent plate boundary.
Answer for screen readers
The volcanoes form an island arc, indicating a convergent plate boundary.
More Information
The presence of volcanoes in this region is due to the subduction of one plate beneath another, causing magma to rise and form a volcanic arc.
Tips
A common mistake is confusing the type of plate boundary. For island arcs, look for subduction zones, not divergent boundaries.
