GEOLOGY

Detailed explanation-1: -Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other. Volcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate.

Detailed explanation-2: -This water lowers the melting point of the mantle material, which increases melting. Volcanoes at convergent plate boundaries are found all along the Pacific Ocean basin, primarily at the edges of the Pacific, Cocos, and Nazca plates. Large earthquakes are extremely common along convergent plate boundaries.

Detailed explanation-3: -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-4: -Composite volcanoes, also known as stratovolcanoes, are found on convergent plate boundaries, where the oceanic crust subducts beneath the continental crust.
