Quizplus · Accepted Answer

The vast majority of volcanism occurs at plate boundaries where tectonic activity is high, making this the best choice. It is estimated that around 75% of volcanoes on Earth are located in the Ring of Fire, a zone around the Pacific plate where the edges of several tectonic plates meet. In addition, there are other significant volcanic zones associated with plate boundaries such as the Mid-Atlantic Ridge, the East African Rift, and the island arcs of Indonesia and the Philippines. Overall, it is estimated that about 90% of all volcanic activity is associated with the edges of tectonic plates.
