A valley and a trench are both elongated depressions in the Earth's surface. They typically form through geological processes such as erosion or tectonic activity. While valleys are often found on land and can be shaped by rivers or glaciers, trenches are usually associated with oceanic tectonic plate boundaries and are much deeper. Both features can affect local ecosystems and water drainage patterns.
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.

The Great Rift Valley in Africa is a geological trench that extends approximately 3500 miles. It is known for its distinctive Y shape and is formed by the movement of tectonic plates, creating a diverse landscape and supporting unique ecosystems.
That is a subduction trench.

the parados was at the back of the trench and was similar to the parapet as it provided shelter and absorbed the impact from exploding artillery from behind the trench preventing it from entering and injury soldiers inside the trench
