How is an oceanic trench formed
Oceanic trenches are prominent, long, narrow topographic depressions of the ocean floor. They are typically 50 to 100 kilometers (30 to 60 mi) wide and 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor, but can be thousands of kilometers in length. There are about 50,000 km (31,000 mi) of oceanic trenches worldwide, mostly around the Pacific Ocean, but also in the … WebThe ocean trenches formed from oceanic plates subducting below continental plates are asymmetrical. The landward side is steep, but the oceanic side may have a gentler slope created by the bending of the oceanic plate as it subducts. Rock composition also differs on the two sides.

WebEarth Science Deep ocean trenches are formed when a continental plate descends underneath an oceanic plate. This is commonly a process of plate tectonics. The Earth’s lithosphere is divided into 17 large tectonic plates and about 20 smaller plates, all of which are continuously moving with respect to each other.

WebTectonic forces create landforms like mountain ranges, rift valleys, and oceanic trenches. When two tectonic plates collide, one plate may be forced beneath the other, a process known as subduction, which can lead to the formation of volcanoes and island arcs.
