Body Of Water

A body of water is a significant accumulation of water on the surface of the earth. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where accumulated water moves from one place to another are also considered bodies of water. Most are naturally occurring and geographical features, but some are artificial. There are types that can be either. For example, most reservoirs are created by engineering dams, but some natural lakes are used as reservoirs. Similarly, most harbors are naturally occurring bays, but some harbors have been created through construction. Bodies of water that are navigable are known as waterways. Bodies of water are affected by gravity, which is what may create the tidal effects.
