The attached diagram shows the locations of the accretionary prism, the oceanic trench, the island arc, and the subduction zone.
Description of these features.
- The Island Arc - This is where the eruption of magma takes places and spews magma from the mantle to the crust.
- Oceanic trench - This is formed when the oceanic plate is bent by pressure.
- Accretionary prism - This is formed when sediments and oceanic crust are scraped from the plate being subducted.
- Subduction zone - Here is where some melting occurs as a result of water being released from the subducted slab.
In conclusion, there are various processes going on at a subduction zone.
