WebAug 25, 2024 · The first is a deep ocean trench that forms a line of the two colliding plates. One plate made of oceanic crust can slide down underneath another plate, forming this narrow, deep trench. 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.

WebMid-ocean ridges, trenches, and large faults mark the edges of the plates, and this is where earthquakes occur (figure 1). The lithosphere is divided into a dozen major and several minor plates (figure 2). The plates’ edges can be drawn by connecting the dots that mark earthquakes' epicenters. WebMar 6, 2024 · Ridges = crust formation Trenches = crust destruction Explanation: Mid-ocean ridges are areas of rifting where two tectonic plates are diverging from one another. Magma rises up through the rifts and forms mountain ranges. The largest is located in the middle of the Atlantic. Rifting creates new crust. flyte hcm employer login
