Zhemchug Canyon is the largest submarine canyon in the world, based on drainage area (11,350 km2) and volume (5800 km3).
What is the name of the largest underwater canyon?
Monterey Canyon, largest and deepest submarine canyon off the Pacific coast of North America. The canyon has three tributaries at its upper reaches in Monterey Bay, California: minor Soquel Canyon to the north, the main Monterey Canyon head aligned east-west off Moss Landing, and Carmel Canyon to the south.

How big is the Zhemchug Canyon?

Was the Grand Canyon once underwater?
The nearly 40 major sedimentary rock layers exposed in the Grand Canyon and in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old. Most were deposited in warm, shallow seas and near ancient, long-gone sea shores in western North America.
What is the difference between a trench and a canyon?
submarine canyon, any of a class of narrow steep-sided valleys that cut into continental slopes and continental rises of the oceans. Unlike deep-sea trenches, which are found in areas where one tectonic plate slides beneath another, undersea canyons are found along the slopes of most continental margins.
Where is the deepest underwater canyon system located?
Zhemchug Canyon is an underwater canyon located in the middle of the Bering Sea. It is the deepest submarine canyon in the world, and is also tied for the widest.
