Question

What do you expect to find parallel to a trench

Answer 1

Answer:

Explanation:

Trenches were made because of plates that bumped or converged with one another along with mountains and other highland forms. So, we can see that Trenches are generally parallel to a volcanic island arc.

Answer 2

Mostly, a trench could be found parallel to a volcanic island arc.

• A volcanic arc is a collection of volcanoes that rise above a subducting plate and form an arc when viewed from above. When offshore volcanoes produce islands, they form a volcanic island arc. When one oceanic tectonic plate subducts beneath another, volcanic arcs emerge, and they usually run parallel to an oceanic trench.
• There are two types of volcanic arcs:  

1. Oceanic arcs emerge when one plate's oceanic crust subducts beneath the oceanic crust of another, generating a volcanic island arc. (Vulcanic island arcs aren't always volcanic.)
2. An arc-shaped mountain belt emerges when oceanic crust subducts beneath continental crust on another plate.
