WebThese trenches form the deepest points in the ocean and are the lowest points on earth. These trenches are formed at a particular place of plate boundary which is known as subduction zone. It happens to form when a plate in ocean hits another ocean plate or it strikes with continental plate. WebWhen a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction. Subduction causes deep ocean trenches to form, such as the one along the west coast of South America. The rocks pulled down under the continent begin to melt.
