Which plate boundary and movement commonly create volcanoes that can result in the development of habitable islands? explain how islands can be created by plate tectonics

1:Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges. Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction. 

2:In areas where the plates come together, sometimes volcanoes will form. Volcanoescan also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate.

I hope this helps!
