Volcano distribution
Most volcanoes occur at divergent (constructive) and convergent (destructive) plate boundaries
The majority of active volcanoes (approximately 75%) are located around the rim of the Pacific Ocean called the 'Ring of Fire'
Hotspots occur away from plate boundaries and are plumes/columns of magma which escape through the Earth's crust
