n: 1. a body of coarse, poorly sorted sediments formed by the coalescence of alluvial or detrital fans along the flanks of a mountain range. 2. a similar body of turbidite sediments formed by the coalescence of submarine debris fans along the base of the continental slope.

n: the transition zone between the continental slope and the oceanic abyss.

n: a zone, adjacent ot a continent, that extends from the lower waterline to the continental slope, the point at which the seafloor begins to slope off steeply into the oceanic abyss.

the shallow area out from shore to a water depth of about 450’.

n: a zone of steep, variable topography forming a transition from the continental shelf edge to the ocean basin.

n: a type of rock consisting of thinly bedded sandstone and shale, thought to be the result of the action of turbidity currents;a succession of turbidites originating in marine depositional basins, usually near the base of the continental slope. Flysch deposites are especially common in the Alpine region of Europe.

n: a dense mass of sediment-laden water that flows down the continental slope, typically through a submarine canyon. It carries clay, silt, and gravel quickly and turbulently downslope in a narrow tongue. When it reaches the more gradual slope of the continental rise, its energy is dissipated rapidly by friction, and the sediments settle out, largest particles first, to form a thick graded bed called a turbidite.
