It could be called a gorge.

Colca Canyon is a tourist attraction which is located in Peru. The canyon is 4160 meters deep and is twice as deep as the Grand Canyon. It is also the third largest tourist attraction in Peru with over 120 000 visitors yearly.
I believe it is the Mariana Trench, about 7 mi deep, off the coast of Taiwan
A long, narrow valley between high cliffs is a canyon. Canyons within mountains, or gorges that have an opening on only one side are called box canyons. Slot canyons are very narrow canyons, often with smooth walls.
A general deep area of the ocean will be called an abyssal deep, but a canyon-like structure will also be called a submarine canyon. e.g. the Clutha Submarine Canyonoff the mouth of the Clutha River on the east of New Zealand's South Island.Off the Kaikoura Peninsula, however is the Hikurangi Trench, a cleft-like canyon which has a relationship with subduction processes, not riverine. This Trench is over 3000 m deep.This structure continues broadly northwards to become the Tonga Trench in that vicinity.
Well, darling, that's what we call a gorge. It's like a fancy word for a deep crack in the earth with cliffs on both sides. So next time you find yourself in a tight spot between two towering walls, just remember you're in a gorge.
The Grand Canyon was formed by the Colorado River cutting through the rock over millions of years, creating a deep and expansive canyon. Erosion from water, wind, and ice also played a role in shaping the canyon's unique landscape.
The Grand Canyon mostly displays sedimentary rocks, such as sand stone. Though if you go deep enough, you can also see some pre-cambrian metamorphic rocks.
The deepest gully within the canyon is Barranca Urique, measuring a depth of some 1,879 meters (6,160.66 feet) of depth.See related links for some photos of Urique.
The purpose of the Grand Canyon is that it is a deep, giant tourist attraction, created from a river that has formed it over thousands of years. it also provides a good understanding of geographical history, based on the layers of rock that can be seen from erosion. This helps people like geologists learn.
probably desert that's what I think! googly goo
A canyon is a deep valley with steep sides, think of the grand canyon most famously to visualise what this is. A gorge is a deep ravine, which usually has a river running through it - though this doesn't have to be the case. Finally a valley is any depression, usually of a certain length, in the surface of the land and often contains a river. So, a canyon is a specific type of valley, with particularly steep sides. A gorge is a particularly deep depression, and will usually contain a river.
