A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water. [2] Most are naturally occurring geographical features, but some are artificial. There are types that can be either.
In practice, a body of water is called a pond or a lake on an individual basis, as conventions change from place to place and over time. In origin, a pond is a variant form of the word pound, meaning a confining enclosure. [12] In earlier times, ponds were artificial and utilitarian, as stew ponds, mill ponds and so on. The significance of this ...

A stream refers to water that flows in a natural channel, a geographic feature that can contain flowing water. [2] A stream may also be referred to as a watercourse. [2] The study of the movement of water as it occurs on Earth is called hydrology, and their effect on the landscape is covered by geomorphology. [2]
Earth's approximate water volume (the total water supply of the world) is 1.386 billion cubic kilometres (333 million cubic miles). [24] Liquid water is found in bodies of water, such as an ocean, sea, lake, river, stream, canal, pond, or puddle. The majority of water on Earth is seawater. Water is also present in the atmosphere in solid ...
Despite the overwhelming abundance of ponds, almost all of Earth's lake water is found in fewer than 100 large lakes; this is because lake volume scales superlinearly with lake area. [21] Extraterrestrial lakes exist on the moon Titan, which orbits the planet Saturn. [22] The shape of lakes on Titan is very similar to those on Earth.
The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard , which is a bed of low permeability along an aquifer, and aquiclude (or aquifuge ), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could lead to the formation of a ...
The Grand Canyon, Arizona, at the confluence of the Colorado River and Little Colorado River.. A canyon (from Spanish: cañón; archaic British English spelling: cañon), [1] gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales.
