In subduction erosion, sediment and rock are scraped off the bottom of the overriding plate and transported into the mantle by the subducting plate.

Question

Quizplus · Accepted Answer

This is the correct definition of subduction erosion. As the subducting plate moves beneath the overriding plate, friction and pressure cause material to be scraped off the bottom of the overriding plate and carried down into the mantle with the subducting plate. This process can lead to changes in the shape and composition of the overriding plate, as well as affecting the geology and dynamics of the subduction zone.
