Sir, when ocean-crust and ocean-crust collide, then the heavier plate will subduct.. In the figure the right side of the plate is subducting so the island arc is formed on the left side of the trench.. so if the left plate subducts, will the trench formed of the left side of the island arc? Am I thinking right? This means the ocean crust of the left side has origin from another oceanic-ridge?
