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.
Jun 14, 2024 · Abyssal plain is a flat seafloor area at a great depth, adjacent to a continent. Learn about its formation, sedimentation, and biodiversity from Britannica's editors.
Mar 8, 2021 · Abyssal plains are flat expanses of sediment and debris on the deep ocean floor, formed by tectonic plate movements and river sediments. They cover about 40 percent of Earth's sea floor and host diverse microbial life.
May 1, 2020 · Learn about the different features of the ocean floor, from continental shelf to volcanic island, and how they are shaped by plate tectonics. Abyssal plains are the largest habitat on earth, covering 70% of the seafloor at depths over 10,000 feet.
The abyssal zone is the deepest part of the ocean, where water temperature is 4° C and pressure is high. Learn about its origin, sediment, fauna, and how it differs from the overlying bathyal zone and the hadal realm.
Learn about the vast, flat, sediment-covered areas of the deep ocean floor, underlain by basalt and covered by layers of sediment and manganese nodules. Find out how abyssal plains are formed, what life forms inhabit them, and how they are explored by deep sea dredges.
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.
