A steep underwater canyon is called a "submarine canyon." These canyons are typically formed by the erosion of sediment and rock by underwater currents and sediment flows. They are often found on the continental shelf and slope, leading to deeper oceanic areas. Submarine canyons play a significant role in marine ecosystems and sediment transport.
An ancient under sea valley carved in the ocean floor is known as a canyon, usually given the name of the contributory river on the land. such as the Hudson Canyon, or the Clutha Canyon.

It is The Marianas trench it is the deepest underwater canyon and i believe the longest at 1580 miles.The mid atlantic ridge stretches 10,000 miles!
They are created in a process known as, subduction.
A valley underwater is called a submarine canyon. These can form through a variety of geological processes, such as erosion by underwater currents or the collapse of underwater sediment. Submarine canyons can be important habitats for a diverse range of marine life.
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.
