It includes oceanic sea drainage basins which have hydrologically coherent areas (oceanic seas are set by IHO convention). The oceans drain approximately 83% of the land in the world. The other 17% – an area larger than the basin of the Arctic Ocean – drains to internal endorheic basins.
Nevertheless, and since ocean basins are interconnected, many oceanographers prefer to refer to one single ocean basin instead of multiple ones. Older references (e.g., Littlehales 1930) [4] 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 ...
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, [1] made up of a succession of elevated features, such as ridges and hills.
This is the category for geologic basins and geographical basins, including geologic oceanic basins, sedimentary basins, geologic depression basins, drainage basins (aka watersheds), and groundwater basins. Some of these are usually thought of in their two-dimensional representation as on a map, however they are all three-dimensional bodies.
Sedimentary basins are region-scale depressions of the Earth's crust where subsidence has occurred and a thick sequence of sediments have accumulated to form a large three-dimensional body of sedimentary rock. [1] [2] [3] They form when long-term subsidence creates a regional depression that provides accommodation space for accumulation of ...
The Amazon basin formerly flowed west to the Pacific Ocean until the Andes formed, causing the basin to flow eastward towards the Atlantic Ocean. [6] Politically the basin is divided into Peruvian Amazonia, Amazônia Legal of Brazil, the Amazon natural region of Colombia, Amazonas (Venezuelan state), and parts of Bolivia and Ecuador.
The endorheic basin that feeds water into Üüreg Lake, Mongolia NASA photo of the endorheic Tarim Basin, China. An endorheic basin (/ ˌ ɛ n d oʊ ˈ r iː. ɪ k / EN-doh-REE-ik; also endoreic basin and endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water (e.g. rivers and oceans); instead, the water drainage flows into ...
