2. Volcanoes and Plate Subduction In the tables below, write in the plates associated with the volcano ranges or arcs. Refer to an atlas or the physical map of the world on the inside cover of your textbook to locate the volcanic ranges. Refer to the map on p. 419 of your textbook, Figure 14-10, to determine which plates are involved. Hint: On convergent plates, the little triangles indicate the direction of submergence.
