![]() ![]() ![]() It is a habitat for a vast number of marine organisms, including fish, crustaceans, and mollusks. It plays a critical role in the oceanic environment. Limited human activity due to harsh conditions, some scientific research and deep-sea mining possible in the future Home to unique species adapted to extreme pressure and darknessĮxploitation of natural resources such as oil, gas and minerals, and fishery resources Generally flat with no significant relief Large, flat area of the deep ocean floor beyond the continental riseĮxtends from shoreline up to a distance of 200 nautical miles Shallow underwater platform that extends from shoreline up to 200 nautical miles into the sea Overall, the formation of continental shelves is likely the result of a combination of these geological processes.Ĭomparison between the Continental Shelf and Deep-Sea Plain Feature Over time, these deposits accumulated to form the broad, shallow shelves we see today. ![]() Erosion and Deposition: This theory suggests that continental shelves were formed by the constant erosion of continental landmasses and the deposition of eroded material along the continental margins.As the continental crust subsides, it allows the shelf to form around it. Subsidence: This theory suggests that continental shelves were formed by the sinking of the continental crust due to geological processes like thermal cooling, compaction, or subsurface loading.As the water receded, the continental margin was exposed, and rivers deposited sediment, eventually creating a broad, shallow shelf. According to this theory, continental shelves were formed when sea levels fell during glacial periods. Eustasy: Eustasy refers to changes in global sea level.Meanwhile, the other plate is pushed up, c reating a shallower area around the continent. When two plates collide, one may be forced under the other, creating a deep ocean trench. Plate Tectonics: This theory suggests that continental shelves were formed by the movement of tectonic plates.However, there are various theories that explain the formation of this feature. Over time, the sediments accumulated and formed a layer that gradually increased the width of the continental shelves. These sediments were transported by rivers and ocean currents, which deposited them on the continental shelf. The continental shelf is mainly composed of sedimentary rocks and sediments like sand, gravel, and mud. It is formed due to the erosion and sedimentation processes that took place over millions of years.
