Body of water
Encyclopedia
A body of water or waterbody (often spelled water body) is any significant accumulation of water
, usually covering the Earth
or another planet
. The term body of water most often refers to large accumulations of water, such as ocean
s, sea
s, and lakes, but it may also include smaller pools of water such as pond
s, puddle
s or wetland
s. River
s, stream
s, canal
s, and other geographical features
where water moves from one place to another are not always considered bodies of water, but there is no other term in English comprising "stationary" bodies of water as well as rivers and canals etc., and such moving bodies of water are included in this article.
Some bodies of water are man-made (artificial), such as reservoir
s or harbor
s, but most are naturally occurring geographical features. Bodies of water that are navigable
are known as waterway
s. Some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans.
The term body of water can also refer to a reservoir
of water held by a plant, technically known as a phytotelma.
