The Ring of Fire

We know about the tectonic plates that make up the Earth's surface. These plates are strongly related to earthquakes and volcanoes. Earthquakes happen because of plate boundaries pushing up against each other. Volcanoes are also related to these plates because they take up magma and release it on the Earth's outer surface and cause the eruption of a volcano.
The type of plate boundaries that are associated with volcanoes include:
Ocean-continent convergent boundary
Ocean-ocean convergent boundary
Continent-continent convergent boundary
Ocean-ocean divergent boundary
Transform-fault boundary
