Deep ocean pressures are to great for submarines. They do not need to go deep anyway, just to avoid detection by the enemy.
deep ocean currents.
January 23, 1960. The Trieste made it to the bottom of Challeger Deep which is the deepest point in all the world's oceans.
They go underground and see what there if it is deep they can use a submarine
A deep valley with steep sides under the ocean is known as a submarine canyon. These canyons are typically formed by underwater currents, erosion, or tectonic activity and can reach impressive depths comparable to those found on land. Submarine canyons provide unique habitats for various marine species and can play a role in the transport of sediments and nutrients on the ocean floor.
The place where the ocean floor suddenly plunges downward is called a submarine trench. These deep underwater valleys form at tectonic plate boundaries where one plate is being pushed beneath another in a process known as subduction. Submarine trenches can reach depths of over 10 kilometers and are some of the deepest parts of the ocean.
Deep trenches are most likely to be found in the western Pacific Ocean, generally the arc between Tonga and the Philippines.
The deepest submarine is built to go 10000 meters under water. This is so they can go to the bottom of the ocean floor.
The deep ocean floor and submarine sand reefs are all made up of limestone environment. Limestone is a sedimentary type of rock that can be found in many places. It falls to the ocean floor when tides rise and fall.

A submarine canyon is a deep, steep-sided valley cut into the seabed of the continental slope, often formed by underwater currents. It can be a conduit for sediment transport from the shelf to the deep ocean.
surface/ open ocean zone was warmer than the deep ocean. Sunlight can reach the open ocean so the temp. is warm.
