Drainage Basin
A river basin drains all the land around a major river. Basins can be divided into watersheds, or areas of land around a smaller river, stream or lake. Large river basins, such as the Neuse and Cape Fear, are made up of many smaller watersheds. The landscape is made up of many interconnected watersheds.
Impact crater is now more prevalently used for the term impact basin.
According to Wikipedia, the three largest river basins/watersheds by area in descending order are: the Amazon basin, the Congo basin, and the Mississippi basin. However, if you list rivers by drainage area, you get: Amazon - 6,915000 km2 Río de la Plata - 4,144,000 km2 Congo - 3,680,000 km2 Nile - 3,349,000 km2 Ob - 2,990,000 km2 Mississippi - 2,980,000 km2
Drainage Basin
Some major drainage regions in the US include the Mississippi River Basin, the Great Lakes Basin, the Columbia River Basin, and the Colorado River Basin. These regions are characterized by their networks of rivers, tributaries, and watersheds that drain into larger bodies of water such as rivers, lakes, and oceans.

Caloris basin is found on the planet Mercury. It is one of the largest impact basins in the Solar System, measuring over 1,500 kilometers in diameter. The basin was created by a large asteroid impact early in Mercury's history.
The Caloris Basin on Mercury was most likely created by a massive impact from a large asteroid or meteorite early in the planet's history. The impact caused the surface to fracture and form the distinctive concentric rings seen in the basin today.
The divides between watersheds in Russia are commonly referred to as "watershed divides" or "drainage divides." These geographical features separate different river basins and direct the flow of water into distinct drainage systems. In Russia, notable watershed divides include the Ural Mountains, which separate the Caspian Sea basin from the Arctic Ocean basin, and the various mountain ranges across the country that delineate different river systems.
The Caloris Basin is an impact basin. It is one of the largest impact craters in the solar system. It was created after the heavy bombardment period and is estimated to be 3.8 billion years old.
