Document Summary

Great fan-shaped deposit of sediment on the deep-sea floor at the base of many submarine canyons. abyssal plain. Very flat sediment-covered region of the deep-sea floor, usually at the base of the continental rise. active continental margin. A margin consisting of a continental shelf, a continental slope, and an oceanic trench. aseismic ridge. Submarine ridge with which no earthquakes are associated. atoll. A circular reef surrounding a deeper lagoon. barrier reef. A reef separated from the shoreline by the deeper water of a lagoon. continental rise. A wedge of sediment that extends from the lower part of the continental slope to the deep sea floor. continental shelf. A submarine platform at the edge of a continent, inclined very gently seaward generally at an angle of less than 1 . continental slope. A relatively steep slope extending from a depth of 100 to 200 meters at the edge of the continental shelf down to oceanic depths. contour current.
