continental rise
The slope is the steep incline at the edge of the continental shelf that descends into the ocean depths. The continental shelf is a gently sloping, submerged portion of a continent that extends from the shoreline to the shelf break where the slope begins.
The accumulation of sediment at the bottom of a continental slope is referred to as continental rise. This phenomenon occurs in oceans throughout the world.
The continental shelf, slope, and rise are all part of the continental margin. The continental shelf is the flat, shallow portion closest to the shore, followed by the continental slope, which descends steeply to the ocean floor. The continental rise is a gentle incline at the base of the continental slope. These features are connected and represent the transition from the continent to the deep ocean basin.
The continental rise is located at the base of the continental slope, where the incline lessens and sediment from the continent accumulates. It marks the transition between the continental margin and the deep ocean basin.
The continental shelf, slope, and rise combine to form the continental margin. The continental shelf is the shallow, submerged extension of a continent, the slope is the steep incline that leads to the ocean floor, and the rise is the gently sloping accumulation of sediment at the base of the slope. Together, they make up the transition zone between the continent and the deep ocean.
The continental shelf is basically an extension of a continent into an ocean. It is underwater during interglacial periods (such as today) but dry during glacial periods. The continental slope is the sloping area between the continental shelf and the continental rise (where the continental plate meets the oceanic plate). The continental shelf and the continental slope together are called the continental margin. The continental rise is located at the bottom of the continental slope and is formed by the accumulation of sediment from the continent. Past the continental rise lies the abyssal plain which is the flat ocean floor.
The area you are referring to is known as the continental rise. It is located at the base of the continental slope and consists of a thick accumulation of sediments that have been transported down from the continent. The continental rise marks the transition between the continental margin and the deep ocean basin.
continental slope
A continental rise forms where the continental slope levels off, and sediment accumulates due to gravity transporting sediments downslope from the slope above. This is a gentle accumulation of sediments deposited by turbidity currents, rivers, and other geological processes at the base of the slope.
The three parts of the continental margins are the Continental shelf, the Continental slope, and the Continental rise.
The great heaps of unconsolidated sediment at the base of the continental slope are known as submarine fans. These fans are typically formed by the deposition of sediment transported by turbidity currents that flow down the continental slope. Submarine fans are important features in understanding sediment transport processes in deep-sea environments.
