✦ Ecosystem Despite the fact that it occupies mere 7 percent of the total ocean floor, the continental shelf accounts for a considerable chunk of the marine life. One of the best examples of the same is the Bering Strait connecting North America and Asia, which was used by early humans to crossover into the New World. When a coastal states continental shelf extends beyond 200 M, the state may establish the outer limits of its continental shelf by submitting particulars of. As a result, there were several land bridges that connected continents, which are today separated by the sea. ✦ History Though it lies underwater today, much of the continental shelf was exposed during the glacial period. The Continental Shelf Programme is coordinated by GRID-Arendal in Norway and was established to assist developing States and Small Island Developing States. This was eventually followed by the layer-by-layer deposition of organic (i.e., primarily made of plant and animal remains) and inorganic matter (i.e., sediments in the form of soil brought in by rivers and other agents of erosion) over the course of millions of years. It submerged in water when sea levels began to rise at the end of the glacial period. Back then, this part of the crust was not underwater as it is today. ✦ Formation The continental shelf was formed when the super-continent began to disintegrate and smaller continents started to drift apart. Interestingly, the shelf is steeper along the Pacific coast as compared to the Atlantic coast. It is the name for the collective area that encompasses the continental shelf, continental slope, and continental rise. The average slope of the shelf is about 10 ft per mile, while the gradient of the slope is around 0.5°. continental margin, the submarine edge of the continental crust distinguished by relatively light and isostatically high-floating material in comparison with the adjacent oceanic crust. On this page youll find 9 synonyms, antonyms, and words related to continental shelf, such as: continental platform, continental slope, land bridge. The characteristics of the various continental margins are shaped by a number of factors. It is the name for the collective area that encompasses the continental shelf, continental slope, and continental rise. This map is a bathymetric or hydrographic map of the North Atlantic ocean floor as it exists today. The Antarctic continental shelf, with a depth of 350 m (1,150 ft), is one of the best examples of the same. continental margin, the submarine edge of the continental crust distinguished by relatively light and isostatically high-floating material in comparison with the adjacent oceanic crust. In some regions, however, a depth in the range of 300 – 400 m has also been recorded. ✦ Depth The continental shelf has an average depth of 60 m (200 ft).
