What are Ocean Trenches and How are They Formed?

WebThe distance between the trench and the arc, known as the arc-trench gap, depends on the angle of subduction. Steeper subduction zones have relatively narrow arc-trench gaps. A basin may form within this region, known as a fore-arc basin, and may be filled with sediments derived from the volcanic arc or with remains of oceanic crust. http://www.visualdictionaryonline.com/earth/geology/ocean-trenches-ridges.php#:~:text=Trench%3A%20very%20deep%2C%20elongated%20cavity%20bordering%20a%20continent,a%20zone%20where%20two%20plates%20are%20moving%20apart.
