Geological features that can formed at a subduction zone is Mid-ocean ridges
Explanation:
Mountains on land are called mountains, which are formed due to tectonic events as learnt in books. But what about mountains underwater are known as ridges. Sometimes even as mid-ocean ridges. These are ridges which are underwater and formed with tectonic plates.
There are two processes come across in them called ridge-push and slab-pull. Under the seduction zone, slab pull is the process that comes into motion. Under this Weight of the heavy tectonic plates are being pulled in the process. Apart from mid-ocean ridge no other geological feature can be formed at the seduction zone.
