Answer:
No Volcanoes are not uniformly distributed. Volcanoes are mostly concentrated on the edges of continents, along island chains, or beneath the sea forming long mountain ranges where two tectonic plates a join or shift. More than half of the world's active volcanoes above sea level form a circle around the Pacific Ocean to form the circum-Pacific of volcanoes named the "Ring of Fire. However what causes volcanoes to even exist is the fact the the tectonic plates have shifted allowing magma to come to the surface.
