has the common properties of the continental shelf and the ocean. The middle ridge of the South China Sea has stopped growing, and the scale of ocean basin is basically stable.
From the periphery to the center, the seabed is the continental shelf, the continental slope, and the central sea basin. It has a slightly concentric three-layer ring structure, and the topography is like a rhombus.
The deepest part of the central subsea of the South China Sea is the central deep-sea basin. It is the basin base of the South China Sea basin. The average water depth is about 4,000 meters, and the deepest point is 4,577 meters (Manila Trench). The bottom is flat, which is in sharp contrast with the surrounding land slope.
