- Continental shelf — the gently sloping, submerged edge of a continent extending from the shoreline to the point where slope steepens. It is relatively shallow (usually to about 200 m), well-lit, and biologically productive, and it contains many marine resources (fisheries, oil, gas).
- Continental slope — the steeper slope that drops from the outer edge of the shelf down toward the deep ocean. It marks the boundary between continental and oceanic crust, often contains submarine canyons, and feeds sediments downslope to the deep sea.
- Abyssal plain — very broad, flat regions of the deep-ocean floor typically found at depths of about 3,000–6,000 m. These plains are blanketed by fine sediments, are among the Earth’s flattest surfaces, and may be interrupted by features such as seamounts, abyssal hills, and deep-sea trenches nearby.
