The shelf usually ends at a point of increasing slope [3] (called the shelf break).The sea floor below the break is the continental slope. [4] Below the slope is the continental rise, which finally merges into the deep ocean floor, the abyssal plain. [5]

It is the largest known ocean canyon off the East Coast of the United States, and one of the largest submarine canyons in the world. The canyon is located near the 100 m (330 ft) isobath on the continental shelf and is 2.2 km (1.4 mi) deep at the base of the continental slope. Over an 80 km (50 mi) distance, the average slope of the canyon ...

[52] Seven main areas are given as: [citation needed] Gulf of Mexico basin contains the Sigsbee Deep and can be further divided into the continental rise, the Sigsbee Abyssal Plain, and the ...
The continental shelf is the relatively shallow water area found in proximity to continents; it is the portion of the continental margin that transitions from the shore out towards to ocean.
