Explanation:

A deep valley that forms where an oceanic plate collides with a continental plate is called volcanoesVolcanoes have a two type of shape (a) Two oceanic plates impact (b) oceanic plate slams into a continental plate Through subduction, the more seasoned, denser Ocean plate sinks underneath the less thick plate at a profound sea channel into the mantle  At the point when an oceanic plate meets a maritime plate, the thinner, denser and increasingly adaptable oceanic plate sinks underneath the thicker, progressively inflexible oceanic plate.This is called subduction
