3. It is said that we know more about the surface of the Moon than the floor of the oceans. Older references (e.g., Littlehales 1930)[1] consider the oceanic basins to be the complement to the continents, with erosion dominating the latter, and the sediments so derived ending up in the ocean basins. Hydrologically some geologic basins are both above and below sea level, such as the Maracaibo Basin in Venezuela, although geologically it is not considered an oceanic basin because it is on the continental shelf and underlain by continental crust. a long, deep depression in the ocean floor. The Amerasia Basin covers the Canada Basin, and the Beaufort and Chukchi Seas and Eurasia Basin includes the Amundsen and Nansen Basins and the Bar- ents and Laptev Sea. In hydrology, an oceanic basin may be anywhere on Earth that is covered by seawater, but geologically, ocean basins are large geologic basins that are below sea level.
