The depth is less important than the proper shoring up of the trench sides. Even a shallow trench can collapse and trap a worker if the sides are not shored up properly.
Answer: 200 meters deep = 656.167 feet deep.
2 feet deep
30 inch's of water how deep
3.4 miles deep
An in-ground pool that is 40 feet by 20 feet with the shallow end being 3ft deep and the deep end being 9ft deep has a volume of approximately 35,900 US gallons. (The depth of variable depth pools is generally calculated by adding the shallow and deep ends and dividing by two).
Trenches
A process known as subduction creates deep sea trenches.
Giant squid primarily live in deep ocean trenches.
A process known as subduction creates deep sea trenches.
Deep ocean trenches are deep slits in the middle of the ocean. The pressure inside these trenches is unbearable. long, curved valleys along the edges of the ocean basin
Trenches, or deep sea trenches.
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
all most 7 miles
They live in deep trenches in the ocean.
a deep-ocean trench is a portion of the earth crust
Deep-oceanic trenches are most abundant around the rim of the Pacific. Deep ocean trenches are surficial evidence for sinking of oceanic lithosphere into the mantle at a subduction zone.
