Answer:
The locations of the volcanoes tend to be close/on the earthquake lines/zones and this is because earthquake activity forms mountains/volcanoes and also causes those volcanoes to erupt. The reason the earthquake zones are long lines is because earthquakes usually happen on fault lines, or where two tectonic plates are next to each other. These plates are like a jigsaw puzzle, as in, they are everywhere making up the pieces of the surface of the globe. So that's why they are long lines.
