Detailed explanation-1: -A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope.
Detailed explanation-2: -In nearly all instances, it ends at its seaward edge with an abrupt drop called the shelf break. Below this lies the continental slope, a much steeper zone that usually merges with a section of the ocean floor called the continental rise at a depth of roughly 4, 000 to 5, 000 metres (13, 000 to 16, 500 feet).
Detailed explanation-3: -A continental slope is the slope between the outer edge of the continental shelf and the deep ocean floor. The continental slope is cut by submarine canyons in many locations. The continental slope marks the seaward edge of the continental shelf.
Detailed explanation-4: -A continental shelf extends from the coastal area to the depths of around 100–200 meters (that is approximately 330–660 feet). They are gently inclined towards the sea at an average slope of approximately 0.1°.
Detailed explanation-5: -A continental slope is defined by the IHO as “the slope seaward from the shelf to the upper edge of a continental rise or the point where there is a general reduction of slope.
