Answer
Continental Margins, Deep Ocean Basins, and Oceanic Ridges.
Work Step by Step
Continental Margins: include the continental shelf, the continental slope, and the continental rise. The boundary between the continents and the deep-ocean basin lies along the continental slope.
Deep-Ocean Basins: Much of the area of Deep-Ocean Basins consist of abyssal plains, which are very flat. Dotting this floor are submerged volcanic structures called seamounts. Seamounts occasionally form large plateaus of similar density to continental crust.
Oceanic Ridges: The most prominent features on the ocean floor, they consist of layers of igneous rock that have been fractured and uplifted from the ocean floor.
