What is the purpose of a trench?
In the civil engineering field of construction or maintenance of infrastructure, trenches play a major role.

A similar use for higher bulk would be in pipeline transport.
What is an example of a trench?

What is the deepest trench on Earth?
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep.
How does a trench work?
TRENCH: An excavation in which material removal forms a narrow opening in the ground. Unlike large excavations, a trench is generally deeper than it is wide. All soil, equipment, and material surcharge loads are no closer in distance to the top edge of the excavation than the excavation is deep.
Why are the trenches so disgusting?
They were actually quite disgusting. There were all sorts of pests living in the trenches including rats, lice, and frogs. They made the soldiers’ itch horribly and caused a disease called Trench Fever. The weather also contributed to rough conditions in the trenches.
Why are trenches zigzag?
The trench system had a main fire trench or front line. All the trenches were dug in a zig-zag pattern so the enemy couldn’t shoot straight down the line and kill many soldiers. If a mortar, grenade or artillery shell would land in the trench, it would only get the soldiers in that section, not further down the line.
What killed thousands of soldiers in trenches?
Approximately 10-15 percent of all soldiers who fought in the First World War died as a result. While the main cause of death in the trenches came from shelling and gunfire, diseases and infections were always present, and became a massive burden for all sides as the war progressed.
