D)Continental rise

Question

Quizplus · Accepted Answer

The continental rise is the part of the passive continental margin that is built up by repeated deposition from turbidity currents. Turbidity currents are underwater sediment flows that can carry large amounts of sediment down the continental slope and deposit them on the continental rise, creating a buildup of sediment over time. The abyssal plain is a flat, featureless part of the ocean floor that lies beyond the continental rise. The continental shelf is a relatively shallow, submerged part of the continental crust that extends from the shoreline to the slope. The continental slope is the steeper part of the transition between the continental shelf and the deep ocean floor.
