An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 meters (9,800 ft) and 6,000 meters (20,000 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains are among the flattest, smoothest and least explored regions on Earth.

The Porcupine Abyssal Plain is a vast, relatively level stretch of seabed with a depth range of 4,000 to 4,850 m (13,120 to 15,910 ft). It has a muddy floor in the abyssopelagic zone and scattered rocky abyssal hills that rise into the bathypelagic zone forming seamounts and knolls. [2]
To find it again, researchers from Utrecht University used geological information from a deep ocean basin off western Australia—the Argo Abyssal Plain—to uncover clues about what could have ...
The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. The word abyss comes from the Greek word ἄβυσσος ( ábussos ), meaning "bottomless". [ 1 ] At depths of 4,000–6,000 m (13,000–20,000 ft), [ 2 ] this zone remains in perpetual darkness.
Madeira Abyssal Plain, also called Madeira Plain, is an abyssal plain situated at the center and deepest part of the Canary Basin. It is a north-northeast to south-southeast elongated basin that almost parallels the Mid-Atlantic Ridge .
The abyssal plain hosts life forms which are uniquely adapted to survival in its cold, high pressure, and dark conditions. [1] The flatness of the abyssal plain is interrupted by massive underwater mountain chains near the tectonic boundaries of Earth's plates. [2] The sediments are mostly silt and clay. [1]
