GEOLOGY

Detailed explanation-1: -Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean.

Detailed explanation-2: -Along plate boundaries, either plates sink below another plate (subduction), heating and creating magma, or plates pull apart, allowing magma to rise to the surface. In both these conditions, when the magma reaches the surface it creates volcanoes. Thus, most of the volcanoes are found on the plate boundaries.

Detailed explanation-4: -Volcanoes at convergent plate boundaries are found all along the Pacific Ocean basin, primarily at the edges of the Pacific, Cocos, and Nazca plates. Trenches mark subduction zones. The Cascades are a chain of volcanoes at a convergent boundary where an oceanic plate is subducting beneath a continental plate.

Detailed explanation-5: -The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. It is largely a result of Plate Tectonics where massive Pacific Plate interacts with less-dense plates surrounding it.
