subduction - 2025 PACE NSC

Question

"Graveyards" formed by this process are a putative source of LLSVPs. Folds occurring at this process’s "hinges" can cause rollback or serve as (20[1])"anchors." Flux melting occurs within regions into which this (20[1])process introduces (20[2]0[1])volatiles like water. (20[3]0[1])Accretion is often paired (20[1])with this process, (20[1])which is the driving force behind ultra-high-pressure (0[1])metamorphism. (20[1])Deep-focus (20[1])earthquakes (20[1])can be driven by this process at the (*) Wadati–Benioff (10[5]0[1])zones (10[3]0[1])that it creates. (10[6])During slab suction, masses (10[1])undergoing this process contribute to mantle convection. (10[3])Volcanic island arcs are formed (10[1])by this process, (10[1]0[1])whose namesake "zones" (10[1])make up (10[1])the Ring (10[2])of Fire. For (0[1])10 points, name this process in which one tectonic plate slides beneath another. (10[2])■END■ (10[4])
