Answer to Question 1

Active continental margins are located along convergent plate boundaries where oceanic lithosphere is being subducted beneath the leading edge of a continent.

Answer to Question 2

Along some subduction zones, sediments from the ocean floor and pieces of oceanic crust are scraped from the descending oceanic plate and plastered against the edge of the overriding plate. This chaotic accumulation of deformed sediment and scraps of oceanic crust is called an accretionary wedge. Subduction erosion is the process of sediment and rock being scraped off the bottom of the overriding plate and transported into the mantle by the subducting plate.
