Where Is The Hadal Zone Located?
The hadal zone (separated from the bathyal by the even darker abyssal zone) starts at the ocean floor around six kilometers below sea level. It consists only of trenches formed by the movements of the earth’s tectonic plates. At the deepest (in the Mariana trench) these stretch to 11km below sea level.

Why is the hadal zone called that?
The hadal zone named for the Greek god of the underworld begins somewhere around 6 000 meters below the surface and ends wherever life ceases to exist in the sediment at the bottom. For decades scientists presumed these depths were a desert in the middle of the seafloor.
Which two zones make up the hadal zone?
They are epipelagic (0–200 m) mesopelagic (200–1000 m) bathypelagic (1000–3800 m) and abyssopelagic (greater than 3800 m) zone [2]. Organisms living in marine biota can be classified into planktons and nektons surviving in the pelagic environment whereas benthos lives in the benthic environment.

The Hadal Zone starts 19 000 feet below the surface and extends to the ocean floor. … The temperature in these deep waters is extremely cold ranging between 1 and 4 degrees C (33.8 to 39.2 degrees F). Sunlight is unable to reach these depths which means the zone exists in perpetual darkness.
What are the three main zones of the ocean?
The importance of light in the ocean is reflected by the description of the ocean’s vertical zones of the water column in terms of how much light these zones receive. The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic dysphotic and aphotic zones.

Is there anything deeper than the hadal zone?
We scientists like to categorise things and the ocean depths are no exception. Depths from the surface to 0.2km is known as the “littoral zone” from 0.2km to 3km the “bathyal zone” and from 3km to 6km the “abyssal zone”. Anything deeper than that is the “hadal zone”.
