Detailed explanation-1: -Continental rises form as a result of three sedimentary processes: mass wasting, the deposition from contour currents, and the vertical settling of clastic and biogenic particles.
Detailed explanation-2: -The continental rise is located around the Earth’s continents, lying at the bottom of the seafloor. The continental rise is made up of sediment deposited by the Earth’s rivers and streams into the ocean and creates a long hill that leads up to the continental slope and then the continental shelf.
Detailed explanation-3: -The continental rise completely surrounds Antarctica covering 39.4% of the Southern Ocean (see Table), forming a halo of sediment surrounding the Antarctic continent. Example of continental rise (in yellow) and submarine fan (red) adjacent to the coast of southeastern Brazil.
Detailed explanation-4: -Continental slope – The slope is “the deepening sea floor out from the shelf edge to the upper limit of the continental rise, or the point where there is a general decrease in steepness” (IHO, 2008).
