Mapping Earthquakes and Volcanoes

In my science class  we started a little project to see where volcanoes and earthquakes normally are.

The guiding question was, "Is there a pattern in the location of earthquakes and volcanoes"? My hypothesis was
" I think that volcanoes form on transforming, diverging, and converging boundaries because the ground would be weak". I think my answer was in a way correct, but I noticed that the earthquakes and volcanoes were also close to each other. My other guess now is that when there is an earthquake it sets of a volcano. I noticed that all the volcanoes and earthquakes are either on or close by a plate boundary.


The volcanoes and the earthquakes are close together and they are on or close to plate boundaries. Now I think that they are by the plate boundaries because when the plates move it makes the ground a bit more weak so the magma can get out and form volcanoes.Earthquakes happen there when the plates move apart, come together, and slide past each other which causes earthquakes. I also think that the volcanoes and earthquakes are situated by each other because an earthquake might set off a volcano or the other way around. If I added more earthquakes to the map I think the pattern would stay the same because it makes sense that the volcanoes and earthquakes are by the plate boundaries. The movement of them can set each of them off.
