GEOLOGY

Detailed explanation-1: -The Ring of Fire surrounds several tectonic plates-including the vast Pacific Plate and the smaller Philippine, Juan de Fuca, Cocos, and Nazca plates. Many of these plates are subducting under the continental plates they border.

Detailed explanation-2: -One such area is the circum-Pacific Ring of Fire, where the Pacific Plate meets many surrounding tectonic plates. The Ring of Fire is the most seismically and volcanically active zone in the world.

Detailed explanation-3: -It traces boundaries between several tectonic plates-including the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.

Detailed explanation-4: -The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
