Question

Several times a year volcanoes erupt along the Aleutian Island chain in southern Alaska. What geologic feature is responsible for these hazardous events? a. convergent plate boundary b. transform plate boundary c. divergent plate boundary d. continental collision

Answer 1

Answer: convergent plate boundary

Explanation: when a plate capped by oceanic crust is subducted under a continental lithosphere an accretionary wedge and fore-arc basin forms an active continental margin between the trench and the continent .the magma that is created by ocean-continent convergence forms a magmatic arc the surface expression of a magmatic arc is either a line of andesitic island such as Aleutian island .
