in a way, they are both part of the process called sea floor spreading. the trench is where the ocean floor is subducted and the rift valley is where the molten material comes up and cools.
This iis a trench.Also ocean basin is the deepest part of the ocean.

a plateau
An abyss is intense cold, 0.6 C to 3.5 C, no light, and lots of pressure.A trench is a boundary between two lithospheric plates.
When two of Earth's oceanic plates collide, they can form a deep valley called a trench. Trenches are often found in subduction zones where one plate is forced beneath the other, creating a deep depression in the ocean floor.
Pacific, Atlantic, Indian, Southern, Arctic, Marian Trench, Puerto Rico Trench, Java Trench, Arctic Basin and Southern Ocean
The Mariana Trench is the deepest point in any ocean and is located in the Pacific Ocean.
well, its the ocean trench. a trench is like a giant ditch and it basically sinks in. while the ocean volcanoes converge and push up.
the answer i Izu the trench
Java Trench
The ocean trench is almost 7 miles deep.
It is the deepest trench in the whole ocean.
