In the structural classification of ocean floor topography, which zone represents the steep descent connecting the outer edge of the continental shelf to the deep ocean floor?

💡 Solution & Explanation

The continental slope marks the boundary between the shallow continental crust and the deep oceanic crust, characterized by a steep gradient ranging from two to twenty degrees. The continental rise lies at the base of the slope where sediment accumulates in a gentler gradient before meeting the flat abyssal plain. Trenches are narrow, deep depressions formed at subduction zones. Continental shelves are gently sloping submerged margins extending from the coast.
