Definitions:

Trench

A narrow, steep-sided, elongate depression of the deep seafloor, formed by bending down of a subducting oceanic plate at a convergent plate boundary; includes the deepest parts of the ocean.

Trench Rollback

Process by which a dense oceanic plate subducts into the asthenosphere, sinks, and tends to bend or roll away from the island arc.

Back-arc Rifting

A geological process occurring behind a volcanic arc, involving the stretching and cracking of the Earth's crust, leading to the formation of a new ocean basin.

Island Arcs

Curved chains of volcanic islands that are usually situated along the edge of a tectonic plate, created by the subduction of an oceanic plate beneath another plate.
