A basin is a depression, or dip, in the Earth's surface. Basins are shaped like bowls, with sides higher than the bottom.
A couple of specific examples of river basins include the Amazon, Mississippi, and Congo River basins. The Amazon River basin is the largest in the world, is found in South America, and flows into the Atlantic Ocean. The Mississippi River basin covers nearly 40% of the lower 48 states and flows into the Gulf of Mexico.
A drainage basin is an area of land where water from rain or snow melt drains downhill into a body of water such as a river, lake, wetland or ocean.
Rivers form large drainage basins by eroding mountainous areas through tentacle-like systems of incising tributaries. The MISSISSIPPI-Missouri River and the Ohio River basins are examples of this basin type. Glaciers create basins by plucking (quarrying) huge chunks of rock as they move over underlying bedrock.
The basin of a river or body of water is the land that surrounds it and the streams that flow into it. A basin is also a sheltered area of water deep enough for boats, or an area of land that is lower than all the surrounding land.
A catch basin is a buried container for receiving and redistributing surface water. The open top is covered with a slotted grate to allow water to pass through while blocking leaves and other debris. On the sides of the basin are holes for attaching pipes that move the water away from the basin.
Regions of deeper water are referred to as basins, trenches or troughs (indicated in blue). Basins and troughs are large areas of relatively uniform depth, much like plains on land, while trenches have much steeper sides, more like river gorges.
The Colorado River flows for approximately 1,450 miles and provides water to seven states in the Western U.S. that are part of the Colorado River Basin. Divided into two regions; the Upper Basin includes Colorado, New Mexico, Utah, and Wyoming; and the Lower Basin includes Arizona, California, and Nevada.
Even though there is one world ocean, it has traditionally been divided into four major ocean basins: the Arctic, the Atlantic, the Indian, and the Pacific.
The five ocean basins from largest to smallest are: the Pacific, Atlantic, Indian, Southern, and Arctic. The Pacific Ocean is the largest and deepest ocean in the world.
The Mississippi River is the largest drainage basin in the United States and the second-longest river in North America. It is also the 15th largest river by discharge in the world. This schematic map of the Mississippi and its major tributaries shows the extent of this watershed.
About 48.71% of the world's land drains to the Atlantic Ocean. In North America, surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern Seaboard of the United States, the Canadian Maritimes, and most of Newfoundland and Labrador.
Arapahoe Basin (/əˈræpəhoʊ/ ə-RAP-ə-hoh; often shortened to A-Basin, or simply The Basin) is an alpine ski area in the Rocky Mountains of the United States, in the Arapaho National Forest of Colorado.
There are 78 major river basins, or watersheds, in the lower 48 states. As water moves from the sky to the land to the ocean it travels overland and through the ground in bounded basins called watersheds.
The valleys forming the Las Vegas ground-water basin are broad structural depressions surrounded by mountains. The climate of the region is arid, and precipitation in the basin lowlands rarely exceeds 5 inches per year.
As of 2021, the Amazon basin, located in northern South America, was the largest drainage basin in the world. The Amazon River and its tributaries drain an area nearly seven million square kilometers.
Lawrence basin, the Pacific basin, the Arctic basin, the Hudson Bay basin, and the Great Basin. Together, the principal basins span the continent with the exception of numerous smaller endorheic basins.
The Great Basin is the largest area of contiguous endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California.
There are five major ocean basins, coordinating with the major oceans of the world: the Pacific basin, the Atlantic basin, the Indian basin, the Arctic basin, and the Southern basin. Many smaller basins are often considered oceanic basins, such as the North Aleutian Basin, between the Pacific and Arctic Oceans.
The Sacramento River Basin is the largest watershed in the state of California, covering 27,000 square miles and carrying approximately 30% of the state's total surface water.
As discussed above, the basic difference between a sink and a wash basin lies in their area of installation or application. The sinks are mostly used in kitchens and pantries and the basins are used in toilets and washrooms. Apart from this, both the sink and the basin have similar functions and purposes.
What we call sinks are in fact 'basins' from which the water 'sinks'. The term sink likely comes from the old English term 'sincan' – to become submerged, go under, or subside. Originally it referred to the place to where the contents of your basin would sink.
