Deep Trench in the ocean floor. It can sometimes be mistaken for a mid-ocean ridge.
hard to say
Trenches are formed by divergent plates, Whereas Ridges are formed by plate in collision.
Abyssal Plain,Ocean Trench,Seamount,and Mid-Ocean ridge
At a distance of 4100 kilometers on the ocean bottom, you would encounter the Mariana Trench, the deepest known oceanic trench. This trench is located in the western Pacific Ocean, reaching a maximum known depth of about 11,034 meters (36,201 feet) at the Challenger Deep.
Both the ocean trench and mid-ocean ridge are features found on the ocean floor as part of the oceanic crust. They are formed by tectonic processes, with ocean trenches created by the subduction of one tectonic plate beneath another, while mid-ocean ridges are formed by the divergence of tectonic plates, leading to the upwelling of magma and the creation of new oceanic crust.
Would not be surprised to find 120 degrees of separation.
It could be called a trench, crevice, ocean ridge, or abyss.
usually a rift or trench
Yes, a large trench known as the Mid-Atlantic Ridge runs down the middle of the Atlantic Ocean basin. This underwater mountain range is where tectonic plates are moving apart, causing new oceanic crust to form in the process.
The further away a point is from the mid-ocean ridge, the deeper the sediment layer should be. Because the ocean floor is relatively new nearer the ridge, sediments have had less time to accumulate.
The ridge of a trench is the parapet.
