WebContinental Slope. The continuously sloping portion of the continental margin, seaward of the continental shelf and extending down to the deep sea floor of the abyssal plain, is known as continental slope. It is charactersied by gradients of 2.5 degrees. It extends between the depth of 180 to 3600 metres. In some places, for example, off the ... WebLarge-scale continental slope/rise deposits are called flysch. These consist of many superimposed turbidites. Submarine canyon: Continental shelves, be they narrow or wide, are characterized by these enigmatic features. These canyons typically start on the continental shelf above 120 m but may extend 3000 m deep. No consensus on their origin.
