"A long and narrow deep trough in the sea floor; interpreted as marking the line along which a plate bends down into a subduction zone. "
narrow, depression of the deep sea floor, on average of 2 kilometers deeper than the surrounding sea floor and may be thousands of kilometers long.
a narrow elongate depression of the ocean floor with a crescent shape in plan view and usually parallel to volcanically active continental or island arcs.
a ditch dug as a fortification having a parapet of the excavated earth
a long steep-sided depression in the ocean floor
any long ditch cut in the ground

In drainage applications, temporary ditch excavated in the ground to install drainage system components.
Long, narrow arcuate depression in the seabed which results from the bending of the lithospheric plate as it descends into the mantle at a subduction zone.
A ditch that is excavated to CMP Construction Standards in which underground wires will be installed from one point to another.
Trenches are deep, linear zones that form where an oceanic plate sinks ( subducts) beneath another plate. more details...
A long, narrow excavation dug through overburden, or blasted out of rock, to expose a vein or ore structure.
A narrow excavation in the earth for the installation of footings, pipes, drains and electrical cables.
Long, narrow, shallow excavation which enabled the movement of reinforcements and provided a shooting position with limited protection from enemy fire.
A long, narrow excavation made below the surface of the ground. In general, the depth is greater than the width, and its bottom (floor) width does not exceed 15 feet.
a narrow excavation (in relation to its length) made below the surface of the ground.
a long cut in the ground, used commonly for water-main replacement and installation in place of capital street reconstructions
usually short for entrenchment, sometimes referring to the ditch of an entrenchment or to an auxiliary entrenchment in rear of a rampart.

A long, narrow excavation, commonly dug for drainage or to install pipe.

In plate tectonics, trenches are tremendously deep features on the ocean floor - deep valleys that reach as far as 11 km below sea level. These trenches are the edge of subduction zones, where one plate is diving beneath another.
