Explanation

The correct sequence of their seaward appearance from the coasts is Continental shelf, Continental slope, Deep sea plain and Oceanic trench. The oceanic trenches are hemispheric-scale long, but narrow topographic depressions of the sea floor. They are also the deepest parts of the ocean floor. A continental slope is the seaward border of continental shelf. A deep sea plain is a broad, almost level area forming the predominant portion of the ocean floor.
