13. For this question, please load the Plate Tectonics.n-file in Google Earth. The file shows the location

of volcanoes represented as triangles.

Look at Pacific coast of Guatemala, El Salvador, Honduras, and Nicaragua (see image below). Would

you expect the volcanoes here to be shield or composite (strato) volcanoes? Why? Would you expect

the volcanoes to be effusive (i.e. calm) or explosive? Why?

(Hint: Look at the type of plate boundary along the Pacific coast. Recall that we discussed how this

type of boundary creates volcanism.)
