continental rise
continental rise A smooth-surfaced accumulation of sediment which forms at the base of the continental slope. The surface of the rise is gently sloping with gradients between 1:100 and 1:700. The width of the rise varies but is often several hundred kilometres. Two types of deposit lead to the formation of rises: turbidites laid down by turbidity currents flowing down the continental slope; and contourites laid down by contour currents flowing along the rise at the base of the continental margin.
