تعريف abisal düzük في التركية الإنجليزية القاموس.
- abyssal plain
- a large expanse of very flat and smooth ocean floor, usually found at depths of 4,600 to 5,500 meters (15,000 to 18,000 feet)
- flat plains on the ocean bottom created by sediment from the continental shelves and slopes filling in the hills and valleys on the ocean floor
- The flat, deep ocean floor It is almost featureless because a thick layer of sediment covers the hills and valleys
- Flat seafloor area at a depth of 10,000-20,000 ft (3,000-6,000 m), generally adjacent to a continent. The larger plains are hundreds of miles wide and thousands of miles long. The plains are largest and most common in the Atlantic Ocean, less common in the Indian Ocean, and even rarer in the Pacific Ocean, where they occur mainly as small, flat floors of marginal seas or as long, narrow bottoms of trenches. They are thought to be the upper surfaces of land-derived sediment that accumulates in abyssal depressions
- Flat areas of the ocean basin floor which slope less than 1 part in 1000 These were formed by turbidity currents which covered the preexisting topography Most abyssal plains are located between the base of the continental rise and the abyssal hills The remainder are trench abyssal plains that lie in the bottom of deep-sea trenches This latter type traps all sediment from turbidity currents and prevents abyssal plains from forming further seaward, e g much of the Pacific Ocean floor See Fairbridge (1966)
- The flat, gently sloping or nearly level region of the sea floor
- The ocean floor offshore from the continental margin, usually very flat with a slight slope
