The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. [1] Continental margins constitute about 28% of the oceanic area.

Major fractures zones of the Atlantic can be seen on this ocean depth map Active Atlantic Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region In the Atlantic Ocean most fracture zones originate from the Mid-Atlantic Ridge , which runs from north to south, and are therefore west to east oriented ...
The borders of the oceans are the limits of Earth's oceanic waters.The definition and number of oceans can vary depending on the adopted criteria. The principal divisions (in descending order of area) of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean.
The mass of the oceans is approximately 1.35 × 10 18 metric tons, or about 1/4400 of the total mass of the Earth. The oceans cover an area of 3.618 × 10 8 km 2 with a mean depth of 3,682 m, resulting in an estimated volume of 1.332 × 10 9 km 3 .
Trenches are found in all oceans with the exception of the Arctic Ocean and they are most common in the North and South Pacific Oceans. [2] There are three types of lithospheric plate boundaries: 1.) divergent (where lithosphere and oceanic crust is created at mid-ocean ridges), 2.) convergent (where one lithospheric plate sinks beneath another ...

These fracture zones displace the Mid-Atlantic Ridge a total of 350 km (220 mi) to the west. The section of the Mid-Atlantic Ridge between the two fracture zones is seismically active. [6] The flow of major North Atlantic currents is associated with this fracture zone which hosts a diverse deep water ecosystem. [7]: 3
