Where can trenches be found?

Where can trenches be found?

Trenches are found on the floor of the sea; however, their common name is deep ocean trenches because they are more often found in the deepest areas of the ocean. Trenches are formed in subduction zones where tectonic plates collide. There are many known trenches that scientists continue to study.

Where are the majority of trenches located?

Trenches are long, narrow and very deep and, while most are in the Pacific Ocean, can be found around the world. The deepest trench in the world, the Mariana Trench located near the Mariana Islands, is 1,580 miles long and averages just 43 miles wide.

Where are most of the oceanic trenches located?

the Pacific
Most ocean trenches are in the Pacific. The loss of the earth’s crust at ocean trenches is made up for by seafloor spreading elsewhere, which is when tectonic plates are pulling apart. Underwater earthquakes at subduction zones can set off dangerous tsunamis.

What are trenches geography?

A long narrow and steep-sided depression on the ocean floor is called a trench. They are deepest parts of the ocean floor and usually 5500 metres deep. The trenches are formed due to tectonic forces—either by down faulting or by done folding.

What are trenches?

A trench is a deep and narrow hole, or ditch, in the ground, like the kind soldiers on frontlines might dig to give themselves shelter from the enemy. The verb trench means to dig or to cut into, but you will most often hear the word as a noun, particularly relating to soldiers.

Were there trenches in ww2?

Trenches (fighting holes, slit trenches, etc) were indeed used in World War II by all major combatants. Their main purpose is to provide fighting cover for troops on the front line from enemy fire, and to fight without providing your troops the ability to gain some kind of cover will quickly diminish your forces.

What were trenches used for in ww1?

Trenches were common throughout the Western Front. Long, narrow trenches dug into the ground at the front, usually by the infantry soldiers who would occupy them for weeks at a time, were designed to protect World War I troops from machine-gun fire and artillery attack from the air.
