What term describes the steep drop-off of the ocean floor?

The term that describes the steep drop-off of the ocean floor is "continental slope." This area is characterized by a steep incline that occurs after the continental shelf, which is the more gently sloping part of the ocean floor situated close to the land. The continental slope marks the transition from the shallow waters of the continental shelf to the deeper parts of the ocean, and it can be hundreds to thousands of meters deep.

The continental slope is significant because it plays an important role in oceanography and marine ecosystems, serving as a habitat for various marine species and influencing ocean currents. Understanding this geographic feature is essential for studying oceanic processes and marine biodiversity. Other concepts associated with the ocean floor, such as the continental shelf, oceanic trench, and submarine canyon, describe different structures and formations that do not specifically refer to the steep drop-off aspect.
