Here's why:

* Steep descent: The continental slope is the steep, relatively narrow zone that marks the transition between the continental shelf (the shallow, gently sloping area near the coastline) and the deep ocean floor.

* Angle: It typically has a slope of 4-5 degrees, which is much steeper than the gentle slope of the continental shelf.

* Erosion and deposition: The continental slope is often carved by submarine canyons and is subject to various geological processes like erosion and deposition, which contribute to its steepness.

Therefore, the continental slope is characterized by a sharp drop-off rather than a gentle slant.
