Question

where do subduction zones often occur?

Answer 1

Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced or sinks due to gravity into the mantle. Regions where this processoccurs are known as subduction zones.Subduction zones circle the Pacific Ocean, forming the Ring of Fire. An oceanic plate can descend beneath another oceanic plate - Japan, Indonesia, and the Aleutian Islands are examples of this type of subduction. Alternately, an oceanic plate can descend beneath a continental plate - South America, Central America, and the Cascade Volcanoes are an example of this type of subduction.
