What Are the Causes of Volcanic Eruptions?

There can be places where these upwellings of hot material occur justw in the middle of a plate. When there's sufficient pressure, and when there's enough of that material coming up, it can essentially burst throughand form a volcano. And so this is thought to be the origin of the hawaiian islands, which occur in themiddle of plate or middle of an oceanic plate. But ut this can occur over land as well. So those are some of the main causes or underlying causes of volcanoes.
