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. They are all landforms, even if some of them are under water or under other overburden.
