A lunar trench is called a Rille (the German word for groove).

They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
The ridge of a trench is the parapet.

A deep ocean trench is a portion of the Earth's crust in which a tectonic plate is being subducted (pushed down) below another plate. At the border of the 2 plates there is a down turned portion of the uppermost plate along the uppermost edge of the subducting plate. Within this area a trench is formed and as correctly pointed out, this plate interaction does cause the deepest places on Earth.
The Deepest point on Earth is the Challenger Deep, which is in the Mariana Trench in the Pacific ocean. It has a depth of 10,971 m (35,994 ft) (6.82 miles).
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.
