Plate Boundaries (earthquakes and volcanoes)
-Plate boundary: where two plates join
-Plates might move toward each other at boundary, away from each other or alongside each other
In other words, most of the world's active volcanoes are located along or near the boundaries between shifting plates and are called "plate-boundary" volcanoes. However, some active volcanoes are not associated with plate boundaries, and many of these so-called "intra-plate" volcanoes form roughly linear chains in the interior of some oceanic plates. You shouldn't see a expected result when looking for one in an experiment. Interpreting the results would leave you a negative. A prediction can come and go. Fault lines change, and so can mother-nature.
